Info tools seems give the legth of the circle instead the arc length. Geom Info was first intended to display Geom etry info. But since I already added a couple of topolgy info in the text (tolerance, 2d curves), it make sense to also display edge length. It now display : Edge Length (+ Geometry cu...

Indeed.
I just pushed a fix.
Thanks.

That's how it is. Most surfaces cannot be parametrized in real world units. The parametric space of a surface is a rectangle. So, I think that only the surfaces that can be developed to a rectangle can be parametrized in real world units. Spheres, cones, torus cannot. Cylinder is a very special case...

Code: Select all

f.check(True)

# Traceback (most recent call last):
# File "<input>", line 1, in <module>
# ValueError: Self-intersecting wire
# Unorientable shape

f.validate()
f.check(True) # No output = good
Part.show(f)

I can move objects in both directions. No problem here.
Does this code really puts the cylinder in (0, 0, 1) ???

Code: Select all

obj = Part.makeCylinder(5,20)
p = FreeCAD.Placement()
p.move(FreeCAD.Vector(0, 0, -1))
obj.Placement = p
Part.show(obj)

The idea was to use the same location computation for the Weight-text node, relative to the circle center, that is used for the Mult-text node, relative to the knot-point. And putting the weight text on the second line, puts it in a safe location, in case of a knot / pole coincidence. But it will st...

However, when I run this file with my python script through FreeCADCmd.exe, I get the following message: Exception while processing file: C:/FreeCADPrototype/tubegen.py ['NoneType' object has no attribute 'hide'] What does this error mean and how do I fix it? I think that Draft.Scale tries to hide ...

I am not that skillful with coin and generally struggle with these alignment issues. So maybe somebody has a good idea about how to best align these two pieces of information so that they do not interfere. A simple solution could be to put this text at the same location as the multiplicity, but on ...
