Curves workbench

[MechaMecca]

Need the file to investigate.

Attached a more simple example.

Indeed the shape sould be hollow. Maybe because OCC cannot be able to do that directly?

Thanks for the file.
I have found the reason of the face creation failure.

Map Sketch on surface not working (on MacOS)
Following the post from another user I tried to Map a sketch on a surface and got errors, they are different for PartDesign

Code: Select all

unexpected EOF while parsing (<string>, line 0)
Failed to get the face support of the sketch

and for Part workbench:

Code: Select all

list index out of range
Failed to get the face support of the sketch

The attached model shows both errors on recompute.

Few short but nice videos on working with Curves WB https://www.youtube.com/playlist?list=P ... igKw1nzS1d

I see no bug, but 2 errors in the use of the tool :
The Mapped_Sketch must be attached to the target face (through the Support property, MapMode has no incidence)
The geometries that must be mapped on the target face in the Mapped_Sketch must be contained in a blue Construction rectangle that represent the face bounding box.

I am not very satisfied with this rather convoluted workflow.
I am working on a new version, that I hope will be more straightforward.

I can't watch this right now (my son is eating all the bandwidth while downloading "yet-another" video game ) but that looks great.

... you are not the only one, whose family is eating bandwidth.
Even with glass fiber and 100Mb.
Especially when also doing homeschooling => Corona go to hell!

Thanks, I will study this later. I don't remember having done this before, perhaps I got it by mere accident right.

Sorry for the noise. I did now what I recommend to others and it is all written in the docs .
