Re: Sweep from BSpline + Sketch

… after scratching with the left hand over the head on right ear - that's too difficult for PartWB Sweep because of the complex curve. You must split it into sections and remove the sharp turns. Is there a (python)-prog behind this 3D-curve? like: https://forum.freecadweb.org/viewtopic.php?f=3&...

Sweep from BSpline + Sketch

Hello, I want to create a solid from an BSpline and an sketch consisting of an circle. I experimented with BSplines and generated this curve and now I want to create an solid so I can tesselate and 3d print it. Can someone link some posts that could help me? I think the sweep function is what I am l...

Re: Remove unwanted faces from face extrusion

@ickby thanks for your comment. Is it however possible to delete the unwanted faces after an extrude. For eg. if the face area is smaller than a particular value, the face edges can be deleted. Thanks. Hello, you can try to defeature the smaller faces. https://www.freecadweb.org/wiki/Defeaturing In...

Re: Face graph - implemented in FreeCAD?

how does FreeCAD handle connections between different objects? Each object has "InList" and "OutList" properties. They reflect connections made by "PropertyLinkxxx". The connections between Faces in the same object can be checked by looking for shared Edges in the Topo...

Re: Face graph - implemented in FreeCAD?

This looks similar to FAG concept (face adjacency graph). You can find a description (with some references) here: http://analysissitus.org/features/features_aag.html. The sources are also available, so you can pick them up and do whatever you want (e.g., why not to add this stuff to FreeCAD's workb...

Re: Open document without showing in GUI

Sorry for gravedigging :)

Did anything change on this matter?

I want to use

Code: Select all

App.ActiveDocument.ActiveObject.Shape.defeaturing
without the document. I didn't find a way to use the defeaturing without the document, so maybe one can open documents without GUI by now.

Greetings brst

Re: Face graph - implemented in FreeCAD?

I want a graph that shows how faces are connected to eachother for analyzing it. I mentioned the dependency graph as one could say that faces that have a common vertex / edge kind of depend on eachother. I don't know if there already is something I could build on or if I need to find out which and h...

Face graph - implemented in FreeCAD?

Hello, how does FreeCAD handle connections between different objects? Is there an internal graph between the objects or do I need to build it myself? (I thought there might be an internal graph for the faces as there already is another, totally unrelated graph, "App.ActiveDocument.DependencyGra...

Re: Shape.BoundBox wrong but right when Part.show() is used before

Is FreeCAD optimized in a way that it won't tesselate a shape again if the shape is unchanged and the tesselation parameters are the same as before?
Is the tesselation operation expensive?
