0:00someone in one of the facebook groups
0:01that i’m a member of asked if anyone had
0:04a
0:05rattan pattern that they could share
0:08and i looked up a picture of it and
0:10thought that doesn’t look too
0:11complicated i could probably draw that
0:14and as an exercise i decided to do so
0:18i shared the pattern in that group and
0:20the response was kind of surprising most
0:22people
0:23didn’t know
0:25that they could do such a thing or how
0:28and so i thought it would be useful to
0:30sort of show what i did and how and
0:34hopefully you’ll learn a few tricks
0:36about
0:37how to draw your own designs in light
0:38burn along the way
0:40so first i’m going to switch out of
0:43filled rendering mode so i’m hitting the
0:45hotkey that is alt shift w you can also
0:48do that from the window menu and just
0:50say toggle wireframe or filled
0:54the retan pattern is actually just this
0:57repeated
0:58and this is actually just three lines
1:01really it’s this vertical line here
1:04this horizontal line here and this
1:06diagonal line here
1:08in a square so i’m going to draw a
1:10square around it just to show you the
1:13part of the pattern
1:15this
1:16section repeats and it rotates 90
1:19degrees for here and another 90 degrees
1:22for this corner and another 90 degrees
1:23for this corner so it is just this piece
1:26rotated and placed here and then rotated
1:29in place here and rotated and placed
1:31here so we’re just going to draw this
1:33piece and i’ll show you how to do that
1:36so first i’m going to draw a rectangle
1:40using one of the tool layers so i’m
1:41going to select my rectangle tool click
1:43t1
1:45and drag this out until it snaps to the
1:47grid
1:48i’m also going to draw
1:50guidelines here that i can use so i’m
1:53going to use the pen tool
1:55and
1:56draw a line
1:59pardon me
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
2:01from
2:04right here
2:05across
2:06and from the same spot
2:09and down until it snaps and this is
2:12important it has to in order for this
2:14pattern to repeat properly
2:17you’ll notice that i counted three grid
2:18squares in from the top here and i
2:21counted three grid squares in from the
2:23side here so these have to line up when
2:26this rotates
2:28and so they have to be the same distance
2:30from the top edge and the side edge in
2:33order to line up correctly and then
2:35i’m going to draw a diagonal line across
2:38this grid square so this is the basic
2:40pattern
2:41and if you take this and duplicate it
2:44and rotate it
2:46and do that again
2:49now i’m not going to cover the hotkeys
2:51that i’m using right now i’ll cover
2:53those later
2:54but it’s basically this pattern repeated
2:57over and over again
2:59so we’ll remove the duplicates that we
3:01just made so this is
3:03essentially our guide for how to build
3:06this shape
3:07now
3:08i’m going to make this middle line a
3:10little bit longer
3:12i want it to actually go out far enough
3:14that when i start overlapping these i
3:17can use it to
3:18slice the other parts of the patterns
3:20and i’ll show you what i mean by that
3:22later
3:23all i’m doing to expand that is holding
3:25the control key so that the scaling
3:27moves from the center instead of
3:30just me dragging it from one corner so
3:32it’s duplicating the scaling that i’m
3:34doing from the middle out
3:37these other lines here these are okay
3:39the way they are
3:40so now we’re going to offset them to
3:42make
3:43the
3:44bars wide effectively
3:47so i’m going to
3:49select a line
3:51choose my offset tool
3:54say outward i want it corners
3:57and i’m going to play with the size a
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
4:00little bit so at one millimeter that’s a
4:02fairly wide line
4:05at
4:060.5 millimeters it’s probably a little
4:09bit too narrow
4:10so we’ll try 0.75 and see how that looks
4:15so i’ll do that one
4:16now a trick with
4:18the offset tool is if you
4:21want to repeat the same offset multiple
4:23times you can hold your control key or
4:26the command key on the mac and just
4:28click the offset button again and it
4:30will redo whatever the last offsetting
4:32operation was
4:35um one thing to note
4:37i am
4:39setting it to corner mode here not round
4:43because i actually want these ends to be
4:45blunt and sharp if you set it to bevel
4:48it’ll offset from the end if you set it
4:50to corner it basically just caps the
4:51line right at the end of the line so
4:53that’s what we’re doing with this
4:57i’m going to do
4:59these three
5:02in black so these are going to be the
5:04actual pattern that gets repeated
5:07but i want gaps in between them so that
5:10you can tell that this line is going
5:12over or under the other lines and those
5:14gaps need to be cut out
5:17and so to do that we’re going to make
5:19another pair of lines
5:21and i’m going to use the t1 layer again
5:23for this and do another offset
5:26and this offset will say
5:29try 0.9 maybe 0.95
5:33that looks like enough maybe
5:36maybe we’ll even go just to a full
5:37millimeter
5:39so i’ll do that one and then using the
5:41control offset trick again i’m going to
5:43repeat that to get these three
5:46and so now these are what i’m going to
5:49use as guidelines for when i’m cutting
5:52the black shapes here
5:55so you’ll notice that in this little
5:57square
5:58this horizontal line goes under the
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
6:01other two
6:03and this vertical line goes over the
6:05other two
6:06so in order to make that happen
6:09for the horizontal line to go under we
6:12need to snip out the part that is here
6:16and here
6:17and you can do that in a couple of ways
6:19and i’m going to show you a couple
6:21different ways to accomplish this so the
6:23first
6:24way to do it is to use the boolean tools
6:26so i’m going to select this rectangle
6:29hold my shift key and select the second
6:31rectangle and then just say boolean
6:34difference or boolean subtract if i
6:36click that it cuts the second thing that
6:40i selected out of the first and so you
6:42can see now
6:44that
6:45my
6:46cutting tool was consumed it’s no longer
6:48available for me to use and it snipped
6:51itself out of these shapes
6:54so i’m going to undo that for the moment
6:56and i’ll show you the other way to do it
6:59and if i go to
7:01edit nodes
7:03and hover here so in between existing
7:06shapes if i hit the t key it will trim
7:10the section of that shape away
7:14and so
7:16now i can just select these bits and
7:18delete them now the one bad thing about
7:20doing it this way is that it doesn’t
7:23close these lines up so i will now have
7:25to use the pen tool
7:27and snapping to draw
7:30black lines it’s important that they be
7:32black
7:34in there and so i’m just clicking on the
7:36ends dragging out a line and then right
7:38clicking to cancel when i’m done and so
7:40that would be the second way you can use
7:41the trim tool
7:43and then add new lines now i’m going to
7:46back all of this up with the undo
7:49because what i really want to do is use
7:51the boolean tools because they’re
7:52quicker
7:53and so
7:54going back to my reference here i want
7:57this one to be over
7:59both of the other lines
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
8:02so i’m going to select this shape
8:05in order to do this i’m actually going
8:07to need to make a copy of this one
8:08because i need to cut twice
8:10so i’m going to duplicate this
8:13select this line
8:14that one
8:15and then
8:16alt and the minus sign on the number pad
8:20is the shortcut for boolean subtract
8:23and so now i’m going to do it again from
8:25here
8:26i’m also going to duplicate this one
8:28duplicate is ctrl d
8:30so i select this line
8:33that one
8:34boolean subtract and so now this
8:37main black center line goes over the
8:41other two
8:42and now i need this horizontal line to
8:44go under the other two which means that
8:47i have to snip
8:48this piece away from it so i’m going to
8:51duplicate this one
8:53select this
8:54and this
8:55and boolean subtract again
8:58or alt minus
9:01and now i have
9:03the basic pattern
9:04i still need to correct this upper
9:06corner however
9:08the bottom corner here if you look
9:12this
9:12reference shape
9:14basically the bottom corner is just as
9:16it is
9:17the top corner however has a cut out and
9:20so that’s the part that we’re going to
9:21do next
9:22um for the bottom
9:24it’s relatively easy for me to just snip
9:27this off and i’m going to do that using
9:30node editing and the trim feature so
9:32i’ll ungroup this because it was grouped
9:34from doing the boolean operations
9:38i will go to node editing
9:40and then i’m going to trim
9:42by hitting t
9:43to trim that line
9:45in this line
9:47and now i can delete that one use my pen
9:50tool
9:51to
9:53again in black
9:54draw from here
9:56to here to here and i’m just using node
9:59snapping to make sure that it snaps to
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
10:00the ends and to the corners
10:03so that is
10:06this shape completed
10:09now i have to do the upper one
10:12so to do that i’m going to select all of
10:15this and actually i’m going to select it
10:16using the crossing selection so
10:19if you drag from
10:21left to right you get a red rectangle
10:24and this is called an enclosing
10:25selection it captures everything inside
10:28it and nothing outside it
10:30if you drag from right to left it’s
10:33called a crossing selection and it will
10:35capture anything that touches it or
10:37anything inside it and so for an
10:39enclosing selection i would have to
10:41capture all of this for a crossing
10:44selection i just have to make sure that
10:45it’s touching
10:46so it’s a little easier sometimes to use
10:48the crossing selection they both have
10:50their uses so i’m going to duplicate
10:52this whole thing
10:53move it over rotate by using my greater
10:56than and less than keys
10:58and
10:59i’m going to group this whole thing just
11:01so it’s easier for me to delete when i
11:02need to later
11:04but now i have a guide here
11:07and you can see this line
11:10right
11:11if i undo that or ungroup that this line
11:15i actually want to extend up like this
11:17so that i can use it as a cutter
11:20or as a guide
11:22and so
11:23now i’m going to select this piece
11:26go to node editing hover over the piece
11:29that i want to remove and hit t to trim
11:31and again over here
11:33and
11:35now i can delete
11:37this
11:38and this which i’m doing by just hitting
11:40the delete key after selecting them
11:44i also need to trim this shape and
11:47actually turn it into just a little
11:49rectangle in the corner there
11:51so i’m going to again go to node editing
11:54and i’m doing this with the hotkey
11:55control tilled
11:57on the keypad
11:59and i’ll trim that little section there
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
12:01and that little section there
12:04and now i can delete this piece
12:07now i’m ready to delete all of this
12:10and
12:12i can do that
12:13by just selecting
12:15deleting those
12:17i don’t need that and now i need to
12:20finish off this little triangle and
12:21finish that line there so i’m going to
12:23do that with the pen tool again
12:27wait until my cursor changes to a snap
12:29cursor
12:34and that’s pretty much it
12:36at this point
12:38i can
12:40hide the other layers that i have here
12:42oops i don’t need to be in pen mode
12:46select this
12:47and if i duplicate it move it over and
12:50rotate it
12:52i’ve done that wrong
12:55i have a tiny little bit out there and
12:57that’s why that rotation didn’t work
12:59correctly
13:01so try that again
13:05so that time i captured that corner bit
13:08so we’ll do this
13:09using crossing selection so i don’t
13:12screw that up again
13:15let me undo
13:18okay
13:19so
13:21grabbing just the parts that i care
13:23about
13:24and rotating there now it’s all lining
13:26up and you can actually see that it all
13:28lines up um if i flip to filled
13:31rendering right now if i go to toggle
13:33filled you’ll notice that not everything
13:35is filling and that is because these
13:38shapes aren’t closed yet so
13:41this line i drew manually
13:44this corner i drew manually and so on so
13:46i’m going to select these
13:48and then go to
13:51edit auto join selected shapes or just
13:53alt j
13:54and when you join shapes
13:57it will
13:58close them up for you
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
14:00so it’s basically select all of the
14:02lines you want to connect together and
14:03hit alt j to join them
14:07and i’ll do
14:09these three up here
14:12alt j
14:14and there’s still a line here that’s not
14:17connecting
14:27there so i just used the
14:29node editing tool
14:31and dragged that one manually into place
14:33to get it to do what i wanted
14:35and so now i have my
14:37shapes filling correctly so if i grab
14:40the whole thing
14:41and group it all
14:45now i can duplicate with control d move
14:48it over and rotate with the greater than
14:50less than keys
14:51duplicate again move it down rotate it
14:54once duplicate again move it over rotate
14:57it and so on and now if i copy this
15:04and change this to filled we now have
15:06our retan pattern and it’s properly
15:08woven
15:10so this will get you
15:13a return pattern that you can fill
15:17it will not cut out properly because
15:19it’s got these vertical lines in it if
15:21you wanted to score it for example or
15:23cut it out
15:24those vertical lines
15:26here where the the breaks are would
15:28cause you some problems
15:30so
15:30this version
15:32of the shape
15:34works well for
15:36filling
15:37but it does not work for scoring and so
15:40we can make
15:41a copy of it
15:43we’ll move it over here
15:44and
15:46remove the
15:47extra pieces that are screwing this up
15:49for when we want to score
15:51and so if i ungroup all of this again
15:55go to
15:56node editing mode
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
16:00i’m going to hit d
16:02while hovering over these lines that i
16:03want to remove so i just want to remove
16:06anything on a border edge of that square
16:09so the outer square that kind of
16:11encompasses this whole thing
16:13is where these lines are going to meet
16:15each other when we tile the pattern and
16:18so any lines
16:19on that outer square need to be removed
16:23and so this version
16:26now is correct for
16:28tiling
16:29with scoring pardon me so if i move this
16:32and rotate move this and rotate you’ll
16:35see that all of these lines meet up
16:37and
16:39it’s a nice seamless pattern
16:41so
16:42that
16:43version right there if i group this is
16:46now what we need for a scoring version
16:49of this pattern
16:51so i’m going to create a copy of this
16:54one
16:55and do the
16:57duplicate and move trick
17:00to get it like this
17:02so this version right now if you were to
17:04group this whole thing not just the
17:07corner but this
17:09this version of the pattern is useful
17:11for filling
17:13and if i take this one
17:15oops not save
17:21and group that
17:23this version is useful for scoring and
17:26i’ll show you what both of those look
17:28like as grids
17:29so we’ll use the grid array tool now and
17:32because the pattern is just a square
17:35it tiles seamlessly and if you zoom in
17:38you can see that it’s tiling nicely so
17:40this if you were scoring the pattern
17:43onto material would give you the nice
17:45weave
17:46and
17:48if i move this one out of the way and
17:50grab this one
17:52flip over to filled rendering mode
17:55and
17:56do the grid array with that one
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
18:00this one gives us
18:02a perfect fill and again tiles easily
18:06you basically set your
18:08x spacing and y spacing both to zero and
18:11that’s padding between edges and because
18:14it is a square pattern it just butts
18:17properly and you get a nice tile
18:21that’s pretty much it
18:25there is a third version of this pattern
18:28that i’ve made that is meant to be both
18:30scored and cut
18:32and
18:34that one
18:35basically you draw cutting lines around
18:38the inside
18:40here very much like
18:46here if i take
18:49this one
18:51we’ll move it back up here
18:55snap it
18:59there
19:01so
19:06ungroup this i’m going to remove
19:08these other pieces of this
19:15so that i have something clean to work
19:16from again
19:19to do the scoring version
19:21scoring with cutting you basically want
19:25to draw cutting lines
19:28along
19:30the outside edges of the black lines
19:33so i’m going to use
19:36uh
19:36switch to the green pen just because
19:38it’s nice and visible
19:40if i start here
19:42and i draw a perfect horizontal line
19:45to there
19:47and then a vertical line to there
19:50and i do the same
19:54let’s do
19:55from this point
19:57perfect horizontal line until we get to
19:59there
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
20:00and then a diagonal up to there
20:04then this one
20:06to there
20:08now this one’s a little bit tricky
20:09because this line you have to go
20:12horizontal
20:13to here so the way that i’m doing the
20:15horizontal line is i’m holding the shift
20:17key
20:18because the shift key will keep the line
20:19horizontal but i can still use the edge
20:22snap
20:23when i get to this line
20:26and then vertical line i’m just using
20:28the corner snaps um and technically i
20:30don’t want this green line across the
20:32top i don’t need that one
20:34and so i just deleted that by hovering
20:36over it and hitting the d key
20:40so i’m going to draw
20:41another line from here snapping
20:45holding the shift key until i get to
20:47that edge
20:50i’m going to draw one this one is a
20:52perfect diagonal and the shift key will
20:54also snap to diagonals
20:57and now i can snap to that point that i
20:59made up there
21:02and then from here
21:05diagonally until i snap to that edge and
21:08down
21:11and now this one i’m going to go from
21:14here across to there
21:18down diagonally to here
21:20down vertically to there
21:24i also want to cut out this inside
21:27triangle
21:28and so this one is a little trickier
21:30again because we need to do a line here
21:33to there
21:36and then one to here
21:38and now i’ll go from this corner
21:40horizontally to here and then vertically
21:42down to there
21:45and we need one from here
21:50and then up to that corner
21:53so if i just
21:54see
21:55the green lines or highlight the green
21:57lines by turning the other layers off
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
22:01or even hiding the other layers
22:03completely you can see that there’s a
22:04green cut out
22:08here
22:09and one here
22:11and one here and one here and one here
22:14and so on and so these green cutout
22:16lines are going to meet
22:18each other when i tile this pattern and
22:21so that is
22:22that is what you want you want those
22:24green lines to meet one another
22:26and so the green lines are your cuts
22:29the black lines become fills
22:33and
22:34the orange lines are guides and you can
22:37simply remove those so i’m just going to
22:41remove my guidelines now because i don’t
22:43need them anymore
22:49and
22:50technically i don’t need most of the
22:52black lines anymore either if i hide the
22:55green lines you can see that there are
22:57still black lines there
22:59and
23:00most of those black lines aren’t needed
23:03anymore i really only need the black
23:05line
23:06here and here to show that this shape
23:08has been scored
23:10so i’m going to
23:12set the green lines not to output just
23:14so that they are
23:15subtle
23:17select my black shapes here
23:22and go to node editing mode
23:24i’m going to hover over this corner i
23:26want to leave this section of the black
23:29line here
23:30so i can do that in a couple of ways i
23:32can
23:34trim
23:35and trim will snip away the line
23:37anywhere
23:38between intersections so that one works
23:41you can also hover over a point and hit
23:44i to insert a node
23:47and so that also works i can hover over
23:50where these intersection points are and
23:51just hit i
23:52to insert new nodes in these lines and
23:56then i can just delete the sections i
23:58don’t want
23:59and so again hit i

24:01hit d
24:03i want to delete that line
24:05i’m going to hit i here delete that one
24:10move over to this shape i don’t need
24:13that line or that one or that one or
24:15that one
24:17on this shape up here i don’t need
24:21any of these three
24:24on this shape i don’t need those two
24:28on this shape
24:30i need to keep these two sections here
24:33in the diagonal and so those ones i’ll
24:35need to insert new points so i’m going
24:37to do that
24:38just wait until the crosshairs show up
24:41to show me that i’m hovered over a point
24:43and insert
24:45and then i can
24:46delete the other points i don’t want or
24:48the other lines i don’t want by hovering
24:50and hitting d
24:54and this one
24:55just delete those two
24:59this one i can delete all three of these
25:02so i need to node edit
25:07and so you can see i’ve now left scoring
25:10lines just to sort of
25:13highlight
25:14where the rattan pattern is supposed to
25:17look like it ends or crosses things
25:21and the green lines are going to be the
25:23cutouts and so the green lines are the
25:25ones where the laser will actually cut
25:26through your material and cut holes
25:29so from here if i group this
25:31duplicate it move it over and rotate
25:33duplicate it
25:35rotate duplicate it rotate i’m just
25:38using the cursor keys or the arrow keys
25:39on my keyboard to move the pattern and
25:41because i chose
25:44a 10 millimeter square to do my work
25:47each cursor movement here moves five
25:49millimeters so it’s just two keystrokes
25:51to move it over the right amount
25:54if you weren’t using a perfect grid snap
25:57like that you can also just hover over
Transcript for LightBurn Projects Drawing a Rattan Weave Pattern (Cont…)
26:00the point like this hover over a point
26:03and drag and when you get to another
26:05point on your design it’ll snap for you
26:07and so that works as well if your
26:09pattern is not nicely grid aligned like
26:11mine is
26:13and so now if i were to group this
26:15pattern
26:17this is ready to go
26:19these lines the green lines will cut and
26:21the black lines will score i would
26:23obviously have to
26:25change my pattern here so that the black
26:27line was also line mode set my speed and
26:30power appropriately
26:32but this pattern if i repeat it
26:37will do what i want
26:42and that’s pretty much it
26:44um hopefully you’ve learned something
26:46from this
26:48you can once you have created something
26:51like this you can save it as a file that
26:53you can then import later or load later
26:56you can also add it to your material or
26:58to your pardon me to your art library
27:01so i
27:02have a library running right now of a
27:05couple of other patterns that i’ve made
27:08and so after you’ve opened your art
27:09library and said new to create a library
27:12give it a name
27:14you can select a section like this and
27:17just say import graphic from project
27:21give it a name and if i call this
27:25new return
27:28it’s now in my art library and then if i
27:30want to use it later
27:33let’s say that i’ve wiped everything out
27:35i can just drag it out of my art library
27:36into my project and it’s ready to go
27:53you
