Hi Efyx,
I think Path's a bit challenged on your model, and you may want to ask further on it. It looks like you mirrored it? For some reason, I can get PathPocket3D to work on the right side, but not the left.

PathSurface3D should work, but you need OCL installed, and experimental features enabled.

I didn't account for clamping or such, and I don't know your material, but I took your model:
*Rotated it onto the XY Plane
*created a Job
*set the Output file and extension
*Filled in Rapid feeds in the SetupSheet
*Deleted the default tool controller
*Added a 3D Pocket
*Added example of Surface3D too....
*Added a Contour cut.

Check out the Wiki--Chrisb has a nice simple walk thru there too ;) ... https://www.freecadweb.org/wiki/Path_Wa ... _Impatient

Best Regards,
Josh

The imported step file brings its own placement and the model is rotated -90 degrees around the X axis. Presumably you want to cut a profile of the shape so it needs to be lying flat on the XY plane.

I rotated the object 90 around X and then did a profile:

Will check all your steps with (essential as I think) positioning of model as

Works fine, thank! Do you know why only half of part can be performed? I cannot add symmetrical part.

No, but Path is still in process, and sometimes things don't work as easily as in others. Key things include getting good models to begin, and I think you''re OK there.

Also, sometimes with Pockets, things get weird about adding multiple faces . If, for example, your part was generated with no center line split it might be different.

Best,
Josh

Thanks, for previous posts. It helped but didn't solved all my problems.
Could someone look onto new attached STEP file and figure out what can be wrong - why path doesn't generate?

You should attach the FreeCAD file, not the Step.

FreeCAD file attached.


Edit: Is it even possible to mill half cylinder (mill goes through on round surface)?

I opened your file and it looks good: There is a path generated all around. I miss the mirror you are talking of

If you want to mill half cylinders you should model half cylinders.
