Can you weigh in on this PDN issue #3146 ?

[toughkrua]

Hello!
I have crash with sweep tool in another case. When I use FCSpring script with several pitch (distance between spire), sweep tool call crash in two version of FreeCAD if frenet option is disable. Another configuration of helix, for example, with different diameters, work well.

Can you validate this behaviour without using FCSpring? If it is a problem with that Macro - which isn't even listed in the Addon manager - it seems to be wrong to create a FreeCAD ticket.
Yet it should be discussed if FreeCAD should be robust enough so that any crash of FreeCAD justifies a ticket.

It is very difficult to create 2D view such a form without the macro, but the file which has been added to my first message, contains the finished 2D view object with B-spline.

It crashes here with solid=true frenet=false. All other combinations are ok.
As a side remark: the diameter of the section is too big, but FreeCAD crashes even with a smaller one.

Perhaps it's worth to mention: No crashes if I do the sweep in PartDesign!

I can`t do it at all with the elements from the file:( "TopoDS::Wire"

Only some of the "Orientation mode"s actually work, others yield errors, but FreeCAD doesn't crash. The errors seem due to OCC issues. You can see it, if you select Frenet and display in wireframe mode: The helix is distorted in the 2nd layer.

Hello again!
I cannot do anything with sweep by PartDesign.
