I’ve been using Lightburn and my OMTech AF-2028 together for several years now. We use Adobe Illustrator to create SVG files then import. I updated to 2.1.01 to find my cut line in pink is importing with different rounded corners. I rebuilt the SVGs, same result. I downgraded back to 2.1.0, and curiously, received the same result. All lbm2 files I have made prior to this show the correct cut line when loaded into LIghtburn.
In Illustrator, this is simply a rounded rectangle shape and does not appear to be any sort of compound object or stacked shape. But Lightburn does not see the rounded corner arc in the same way as Illustrator intends to to be seen.
Thanks, took your advice and the SVG looks correct in Chrome. So this helps me at least start looking deeper in Lightburn to see if there’s an option or checkbox that I might not have set correctly.
If this sparks recognition in anyone, I’d love more insight. I’m sorta going to go through the menus blind until I figure it out.
Feel free to email privately to support@lightburnsoftware.com (include a link to this forum topic) and happy if you want to remove the bulk of the content and just leave the two border shapes with the radius issue.
Hello, I am having the same issue as described above. Windows 10.
Rather than create a new post, I will add what I was about to post.
My issue has appeared since version 2.1 and all versions onwards.
When I import certain rectangular shapes with radius corners from old project files I have saved, or when importing SVGs from my workmate’s AI files, the shape seems to change once it lands in the workspace.
If I open the files instead of importing, the shapes appear normally and correct.
Have a look at the example in the attached picture. The shapes on the right in green are correct, as per old saved projects I have been using for months, even years. The shapes on the left in red, are what the imports turn out like.
I can work around this by opening instead of importing, otherwise I can rollback to version 2.0.05 to continue working like I am used to.
At this point in time, I can’t seem to identify why this is happening. If I save what’s in the attached picture as a new project, it will still change the shapes when I import it again. The thumbnail preview in windows explorer shows the correct shapes.
Anyone have any insight as to why this is happening, and why it began after version 2.0.05 ? Does how my workmate supplies their SVG’s have something to do with it? I imagine that is the case.
This is likely from new code that tries to fix a different sizing issue. If you draw a rectangle that’s 10 x 10, then group it, and scale the group down 50%, you’re applying a scale to the group itself, and “by proxy” to the shape it contains.
If you ungroup, we used to bake that group scale onto the objects, but the rectangle would still have “10 x 10” as the size, even though it was half the size, because the scale isn’t exposed.
Changes were made to push the scaling back onto the object when possible, so that 50% scale would get applied to the 10x10 instead of scaling the object, so now the object scale would still be 100%, and the rectangle would be 5x5, as people expect.
The dev who wrote the code appears to have missed updating the corner radius property.
While I’m not familiar with the technicals behind the scene that Oz mentioned, and I can’t recall my exact steps, I can confirm that all my affected project files did involve a lot of grouping/ungrouping, scaling and offseting of rectangular shapes with round corners in their preparation.
In response to RalphU’s request to upload an SVG, I’m terribly sorry, but after reinstalling forward and back between version 2.0.05 and 2.1+ several times for testing and restarting the PC several times, the SVGs are now importing correctly. As such, I can’t confidently upload an SVG that had the issue without guessing, and I’ve tested all my SVG files from the last few months and they are ok now. It was actually only a few SVGs that were affected upon import, my main persisting issue is with my old saved project files when importing into version 2.1 onwards. I’m sure Oz has honed in on the issue for now.
Just in case it matters, all my work originates as SVGs created and exported from Illustrator.
Actually I spoke too soon. My workmate just handed me a new SVG today and upon importing it into Lightburn, and then ungrouping all of it, it altered the rectangle shape with small corners to having a full oval shape. Im working in Lightburn 2.1.00
As a test, I asked my workmate to specifically ungroup the object first then export it back to me, however it still alters the shape when I ungroup it myself in Lightburn.
Not sure what my workmate can do to fix this, or whether it remains fully a Lightburn issue.
It’s the act of ungrouping it that’s messing it up, but we have a fix already, and I’ll talk to Adam about timing for the next patch. We try to space them out a little so people don’t freak out.
