Re: Santed: Workflow for two Parts

Many thanks papyblaze for your cool solution!

My Learnings:
  • Draw Sketches in the space not attached to faces (better for reuse)
  • Use Symmetry (here it would be interesting to make use of the XY-plane symmetry)

Wanted: Workflow for two Parts

Hello FreeCAD-experts, I want to create a mount that connects a tube to a rectangular rod with FreeCAD (0.18) as shown in the Picture. Beamholder.PNG My workflow is: Lower Body: (straightforward) Create a solid (cube) and make a bar. Convert it to a Body With Sketches create material takeaways under...

Re: How to get faces in two sides of a serpentine wall?

I would try the following: Let us assume: - all the line segment vectors of the center line (red dotted) are connected in the same direction (end point of a segment vector is start point of the next segment) - the unit normal vector of the center face of a wall segment be n (line segment vector dot ...

Re: Unlimited references to external geometry

DeepSOIC and triplus: many thanks for your investigation. I was not aware that I generated an redundant/overconstrained situation. I was on the wrong track with the orphaned edge assumption. So it is good that a fix could be done by simply removing some constraints. I am looking forward to see the d...

Re: Unlimited references to external geometry

One problem in FreeCAD is that sometimes the edge and vertex objects change if one adjusts the sketch geometry. Instead of changing only the size of the objects new ones are created leaving "orphaned" edges and vertices and the linkage get lost. In the example file: Changing the length of one side i...

Re: Unlimited references to external geometry

Does Assembly really help if one wants to make fully parametrized objects? I agree that it is sometimes very difficult to find a glitch with unlimited reference. Mainly due to the fact that the vertices or edges change sometimes. I also agree that objects with cascading references tend to get obfusc...
