LightBurn Demo 03 – Usability Features

0:00 so I thought it’d be fun to show off

0:02 some of the new LightBurn usability features that

0:04 I’ve been adding to lightburn so here

0:07 we go

0:12 one of my favorites is this

0:17 drag-and-drop so you can pull files out

0:20 of your desktop drop them on to lightburn

0:22 they will import as appropriate for

0:25 the format so this is an AI file I can

0:27 do the same thing with bitmaps it’s a

0:32 small thing but it’s actually kind of a

0:34 big thing we also have cut and paste now

0:37 so I can create duplicates of things

0:39 easily

0:43 of course there’s still full undo so

0:47 yeah cut copy and paste all work the new

0:52 preview is kind of cool you find a file

0:56 it’s appropriate for previewing this one

1:04 alright so this is a fairly complicated

1:06 vector file if I set this to just cut as

1:11 it is here and I run the preview you can

1:14 see you just get cut out lines here and

1:20 I can rewind the preview and watch

1:22 basically how it’s going to cut in what

1:25 order everything is going to cut so this

1:29 is kind of a way to check your work to

1:30 see what the cut planner chose to do

1:33 with your stuff when you’ve got things

1:35 that are arranged a little differently

1:51 okay so here we’ve got six pumpkins

1:54 they’ve got small inner vectors and

1:58 outlines little things inside that kind

2:00 of thing so the way that you would want

2:02 these to cut would be obviously the

2:04 inners first and then the other curves

2:06 you don’t want you cutting your outside

2:09 first and then the small stuff in the

2:10 middle

2:10 so in this case

2:12 if we look at the preview we can see

2:14 it’s doing all of the inside curves

2:16 first then following with the outside

2:18 curves and it’s also trying to optimize

2:20 the path travel to reduce rapid moves so

2:24 again a small thing but it’s a useful

2:27 thing some navigation stuff for people

2:32 who are used to working on a Mac got

2:34 dragged the view what else frame the

2:40 current selection will frame everything

2:43 or it will frame whatever you currently

2:46 have so if I don’t have stuff in my

2:50 earthly so I don’t have a selection and

2:52 I hit frame will frame everything that’s

2:54 currently on the page in fact if I don’t

2:57 have any selection at all it will just

2:5 frame the page for me I’ve also made

3:03 some changes to the offsetting tool so

3:05 it performs a lot better the results are

3:08 considerably cleaner so if I make sort

3:11 of weird arbitrary shape here and I run

3:16an offset of that first of all the

3:19 offset is quite a bit faster don’t

3:23 really notice it on small stuff but you

3:25 do notice quite a bit on big stuff this

3:26 is the important one here though this

3:28 optimizer simplify results if you leave

3:30 that off if I look at the output that

3:34 this generates you can see that these

3:35 points are all for these curves so they

3:38 are all very very fine points if I run

3:43 an offset width if I run an offset width

3:50 that simplification enabled so we’ll

3:53 push this curve out just a little bit so

3:56 you can see both select both of these

4:00 curves and look at the node outputs and

4:02 so you can see this one generated nice

4:05 splines this one generated tons of

4:07 points the two curves are equally

4:09 accurate I’m running explain fit

4:12 algorithm or a curve fit algorithm over

4:15 the resulting points after it’s

4:17generated the shape and it does a good

4:19 job it also means that if you offset an

4:23 offset

4:25 the results don’t get full of points

4:27 like they used to and so that’s kind of

4:28 a big deal I wanted I wanted it to be

4:31 able to handle offsetting an offset of

4:33 an offset of an I said and you know

4:36 recurse infinitely in that curve and so

4:43 now you can see even the offset of the

4:46 offset is still quite clean there’s a

4:48 few extra points but it’s not bad so I’m

4:52 happy with the result and finally one

4:58 last thing again it’s a small feature

5:01 but it’s a useful feature I didn’t have

5:04 it before and I’m sorely missed we now

5:06 have the ability to aspect lock so if I

5:08 use the numeric editor to change this to

5:11 be narrower this is what you used to get

5:14 if you enable the aspect look and I type

5:18 that in you can see it maintains the

5:19 aspect ratio correctly the drag still

5:21 works the way it used to so you can

5:23 still drag from corners and all of that

5:26 however those can be constrained as well

5:29 by holding the shift key and if you hold

5:32 the shift and control keys it does the

5:33 scaling from middle out so you can do

5:37 scale from middle or lock the aspect

5:40 ratio when you’re holding these corners
