3d face go though object

Post by wbeppler »

hi,
my problem is that if i import a step-file (from grabcad) and want to make a cnc-program the path goes though the object lke in the picture.
i hope it is visible, there are green lines under the object. at the top the lines stop like the heigh gut under the top they go again.
why ?
what am i doing wrong ?

Hi,

Please could you post your FreeCAD version?

See here: https://forum.freecadweb.org/viewtopic.php?f=3&t=5236

There has been a significant amount of work done on 3D toolpaths recently.

Cheers,

Dan

Please can you post a link to the grabcad model or share your FreeCAD model?

I will try it on the development build.

Thanks,

Dan

The 3D Pocket OP fails for this use case, However the 3D Surface operation generates tools paths:

If the path could be contained to an area or surface more easily this would be ideal.

Thanks,

Hi,

You will need to install OpenCamLIb (OCL)

https://www.freecadweb.org/wiki/OpenCamLib

It should appear under the same menu as the 3D Pocket Operation.

Thanks,

Dan
