Sometimes there are errors if the parts have faces in the same plane.
Maybe this is the reason.

Re: Making Sweep using Bezier Curve
in inflection points of splines where the curvature becomes zero the normal and the binormal vectors can flip by 180°.
possibilities:
1. split ypur curve into subcurvs without inflection points.
2. insert extra ribs to these tricky places.
3 use other methods than Part.Sweep

Re: GeoData Workbench
yes they are all needed, but it seams gdal is only needed for the some special import geodat import AST (gdal) It should be possible to run GeoData without it. microelly2 should now any better ping Yes, gdal is only used for this special case. The same is for cv2 - it is not needed for the core dow...

Re: node editor - pyflow
It would be very helpful to do this parameter based as it would give much more and easier control in case of variation. Would it be possible to have control about the "unfolded" width and height of each triangulated quad by the node editor pyflow? Yes we can. This is the construction of an offset c...

Re: node editor - pyflow
approximate a curve by a simple bezier curve (4 Poles) with tangent constraints at the endings.

Re: node editor - pyflow
Find a curve with these constraints:
start and endpoint
tangent direction at start and endpoint
curvature at start and endpoint
result is a 6 poles bspline degree 3.

Re: Krümmungsstetigkeit
Ich habe mir nochmal Gedanken gemacht, wie man die Krümmungen und Tangenten als Randwerte für eine Kurve hinbekommt.
Mit 6 Polen kann man eine solche Kurve berechnen lassen.

Re: GeoData Workbench
the use of urllib instead of requests would be another option, as urllib is included in FreeCAD LibPack, but it seams this could be some crucial question. This should not be a problem. Another idea is to download the whole osm database or a country and store it into a local database and implement t...

Tiller empfehlen. Der letzte Teil Deiner Aussage hat mich etwas irritiert. Du sagst, wenn die beiden Abstände de...
