Re: SVG Import issues

Hi,
You probably know this, but just in case, are you all using the same bounding box model in Inkscape ?
- Edit -> Preferences -> Tools -> Bounding box model to use -> Geometric (ignores stroke width) or Visual.

Re: Curves workbench

OK. Thanks.
But ... why would you call segment surface on this face ?

Re: Hidding a Slice

Slice_group = CompoundTools.Explode.explodeCompound(f) # Creation of "Exploded Slice" Here, Slice_group is a tuple : ( group_object , list_slice_objects ) Be careful, group_object can be None, if there is only 1 slice part. So you'd better use the slice objects from list_slice_objects . These are A...

Re: Curves workbench

JoinCurve is exactly aligned with the face border, on the left side : this is looking for troubles.
You should make trim curves that extend beyond the face to trim.

Maybe :

Code: Select all

s = Part.Shape()

Your tessellation values are probably too high :

Re: smooth airfoil

The name of the object has changed.
It should work by replacing "DWire" with "Wire" in the first line of the code :

Code: Select all

obj = FreeCAD.ActiveDocument.getObject("Wire")
pts = [v.Point for v in obj.Shape.Vertexes]
import Part
bs = Part.BSplineCurve()
bs.interpolate(pts)
Part.show(bs.toShape())

Re: Collision detection without cut or common

I assume there is no other way than a cut or a common to check if two objects are colliding and not adjacent? Because it also seems quite an expensive operation for what you want to know. (If you know that one point is inside of the other object you already know sufficient in fact). Maybe Shape.pro...

I think it's not G0,G0,G1, it's C0, C1, C2, where C stands for continuity.
Both G and C continuities exist.
Here is a pretty good explanation :
