Curves workbench

To avoid self-intersection, it is generally better to choose the steepest and shortest Sweep path possible.

Your AdditivePipe should use the green binder as Sweep Spine.

I'll do that. It makes sense - create line then bind it into model and then use link in model.

However, the generated sweep still self intersect.

Both inside and outside surfaces look fine in my version of FC, and my Slicer accepted it as all clear. I'll see what the printer makes of it.

Updated Wb, and Curve On Surface is vanished?

[Chris_G]

It was only used by BlendSurface.
And BlendSurface has been totally rewritten, so that it takes directly Edge1, Face1, Edge2, Face2 as input selection.
But I only removed it from Gui toolbar; old project files can still load CurveOnSurface objects.
Did you use it for another purpose than BlendSurface ?

[Vincent B]

you mean curves on surface?
It was usefull: "ribs" (bordure ou rebord en français), offset a curve on a surface....
not only for blend surface.

[Chris_G]

OK, then I'll restore it in the toolbar.

EDIT : OK, Done. Funny enough, it seems you use the workbench more than I do myself

[Vincent B]

Thanks, I will show two examples.

i work on win 10.
Glad if anyone would help. Thanks in advance

Hello,
What result do you get if you type this in the python console ?

Code: Select all

from scipy.optimize import minimize

Also, please post you FreeCAD info.
