Summary0001976: Error when sweeping a ruled surface
DescriptionWhen sweeping a ruled surface, an error occurs. The first time I encountered this error, it wrote something like "Error when writing {adresses}". Then I re-launched FreeCAD and the error occured again, but without anything written in the error box.
Steps To Reproduce-Defining a ruled surface (in my case: a pipe cross section)
-Defining a path
-When making the sweep, the ruled surface appears in the column Vertex/edge/wire/face.
-Selecting the rule surface as the sweeping section
-Selecting the path
-Clicking "OK"
-It should fail
Tags#pending, sweep

Can you please provide your OCCT version.

The sweep is not the problem. The Sketch001 is fails the BOPCheck and there should be a better way to get a planar face, than a ruled surface.

There seems to be a problem with the ruled surface damaging the vertex tolerances

@shoogen is this an upstream issue?

@JPouX I know this is ancient history but is there any possibility you can reupload your attachment to this ticket?

@NormandC can you recreate this issue from scratch?

I think I did, based on what I could understand. But as shoogen wrote back in 2015, it does not make sense to create a ruled surface from a sketch. 3 years later, the PartDesign workbench now has an additive sweep tool that can sweep a sketch made of two closed profiles inside one another (like a pipe section).

In the attached file FC_Issue1976_Sweep_Ruled_Surface_Error_nc1.fcstd, trying to generate a sweep using Ruled_Surface as profile and Sketch as path produces a BRepFill_Sweep::BuildEdge error.

I believe we should ignore this issue and close the report as it's not a proper work flow anyway.

As suggested by normandc the PD workbench offers a proper workflow to do this the right way.
