CAM: Strange behaviour while generating the gcode for pocket milling

The DXF was drawn in Fusion 360 and then imported to SketchUp for combining the lines to polylines - please don’t ask why I did it this way. ;-). When I then generate the operation with these dxf paths, it takes less than 2 seconds (Ellapsed: 00:01.558).

But when I do the combining job in Inkscape, then it takes ages until it’s done (if ever). Also no better result when I draw the rectangle and the circle directly in Inkscape.

So what about the SketchUp toolchain? Unfortunately importing DXF is a pro feature and plugins which added this function seem to disappear.

Any hints?

Edit:
With the native Inkscape shapes it took: Ellapsed: 21:09.680
With the imported and combined shapes : Ellapsed: 11:05.045

Here you can get the different DXF files: https://we.tl/C5L8wnUiMU

Did you add a segment value?

@Ariel_Yahni_UniKpty Yes and I imported all versions (SVG and DXF) and replaced the shapes. This way I was able to provide identical conditions.

So all this coming from inkscape? I know I wrote it somewhere an option to fix that on inkscape but I can’t find it

@Ariel_Yahni_UniKpty With both Inkscape variants it took between 11 and 21 minutes. The “SketchUp” pocket was generated in less than 2 secondes…

There something in inkscape that improves that I just can find that post

@enhydra Try this open inkscape and select all and ungroup, the go to extension / modify path and choose a very tiny value for example 0.1 ( this should not change anything on the design but pay attention )
Save as SVG and load in inskcape

@Ariel_Yahni_UniKpty Perfect, that solved the issue. Thank you very much. :slight_smile:
