I posted a week or so ago about this issue. However when I linked the file that file had two nodes in the point which made it a flat spot. I think I have narrowed it down to the angle being less than something. Lets say I use a 1mm offset on a triangle and one of the corners of the triangle is a tight angle less than 45. I don’t know the exact angle it starts happening. The offset will clip the corner off the shape it creates making the point a bevel. This is with corner selected in offset. I don’t recall this being an issue in the past. I am not sure what changed or what I need to change to get the desired results. I can work around this by editing nodes and such but how do I just get the shape to exactly offset the same shape at the desired distance?
The offset tool has an internal “miter limit” - if a corner will extend more than 3x the offset distance from the generated shape, it is beveled. That limit isn’t exposed to the user anywhere, so it’s not something you can override.
Inward offsets don’t do it, so if you start with the largest shape you need and offset inward, it should do what you want.
I don’t exactly know the end size for my shapes to figure out what the outer size would be. I am making complex geometric patterns to then turn into a stepped multi layer work. I have been making them from the top down using the both offset but I guess I hadn’t gotten triangles with such sharp angles before to run into this. When I had run into it it didn’t end up mattering as the shape I had issues with ended up being inside another that was getting merged together where they overlapped. Attached is a quick sample of where I start. I don’t use Inkscape or Procreate because I am not too familiar with those. I do however have a lot of AutoCAD experience like 20 years ago so LightBurn flows best for me.
