Bug: Wrong scaling when import dxf files #2024

Open Obicom opened 1 year ago

Obicom commented 1 year ago

Bug report If I import a dxf file in Luban 4.6.3 it is always with the wrong scaling. It is shown as a very small object and I have to resize it manualy. If I open the file in Fusion360 or Inkscape the scaling is fine.

Expected behavior If I import a dxf file in Luban I would expect the right scaling of the objects.

My Environment Snapmaker Artisan with latest firmware Luban 4.6.3 (Windows version)

Can you provide the wrong file and point out its correct size. This problem seems to be caused by the units.

I was able to reproduce this with a very simple square exported from OpenSCAD. It seems broken both an SVG and DXF. The OpenSCAD script saw just square(100); and then I exported as SVG and DXF and imported into a 3-axis laser job where they showed up as 10mm.

I forgot to mention that this was with Luban 4.10.1 on Windows.

The reason I believe this should work is when I generate an stl from an OpenSCAD file with cube(100); in it and import it into a 3d-print project, it imports as a 100mm on a side cube and is what I expect.

I have the same problem. When I import a simple rectangle, the mass times 10 works. I have a project with connectors. The general dimensions are correct, but the connectors do not line up. The dimensions in Fusion 360 are correct. Also when I load it into Adobe Illustrator the connectors line up. I think this is a rounding issue as Luban only supports one decimal place. The only possibility is to put all my parts on one DXF. Unfortunately this makes Luban almost useless for laser cutting. I used Luban 4.10.1.
