Hi,
I am discovering pycam features and I like it. I want to use it to make gcode for my small cnc router, 2d wooden sheets milling.
The most used process for me is gravure. I am able to make pretty good gcode for closed contours, holes and shapes.
Now I met challenge how to create toolpaths for open curves. I mean how to move tool along for example single line or arc. Or line followed by arc, etc (not polyline librecad type).
I am looking for it because I need to interrupt outer part contour by several "bridges" to hold part in workpiece sheet after machining.
Is any way how to do it in pycam except manual gcode change?
Have been the similar topic discussed here? I didn´t find.
My pycam is 0.5.1.1.
Thanks for hints.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Regading open or closed curves: pycam does not treat open of closed curves differently. Thus just go ahead: open an SVG or DXG model in pycam and generate a toolpath.
(or use the intergrated single-line fonts - they are also open curves)
Enjoy!

Thank you Lars,
today I found your video regarding "bridges" maintained in Model extensions section. I tried and it works as I need :-).
But my different problem regarding open curves remains. I am sure, I do something wrong. When I use test file pycam_test3.dxf (attached) where all shapes are closed, pycam makes nice gcode for me (see pict. pycam_smooth.png).
When I use file pycam_test3_divided.dxf (attached) where I split outer shape into several open curves, pycam makes only internal shape toolpaths - see pict. pycam_divided.png.
My intention was to make "bridges" already in dxf file. I know, you implemented bridges feature just into pycam, as I noted, but I would like to be able to know mill open curves in similar cases.
I also attached log file where are logs when pycam_test3_divided.dxf was maintained.

I am glad, you have fun!

Is possible to ivestigate what do I wrong?
Thanks.
