I'm trying to create an interlinked star geometry with FreeCAD. I'm using this (Solidworks) tutorial as a "guide": https://learnsolidworks.com/solidworks_ ... solidworks
Currently, I'm stuck at this step:
Here, the top blue surface was cut out of a sphere, so it is curved. The bottom blue surface is planar. With Solidworks, they selected the two edges and applied a surface loft with tangent constraints.
After exploring the Surface/Part/Curves workbenches, I think this step requires a bit more of manual work to be done with FreeCAD. What approaches can I try? I'm attaching my current file if someone would like to give it a try and then explain the process.

Re: Surface Loft with tangent constraints
Solidworks and FreeCAD have different workflow, and different "3d engines" so probably workflows are not matching.
And probably different "3d engines" mean also different "3d concepts", did you see:

Probably there are problem, but maybe posting directly on:
https://forum.freecadweb.org/viewtopic. ... start=1350
Will result in a more quick response.
Kind Regards.

Re: Surface Loft with tangent constraints
hi, did you finished the challenge? I've got a self Intersection here.

Re: Surface Loft with tangent constraints
Would you please upload the model? also, were you able to fix the overlaps and self-intersection that you mentioned? I would be very happy to see FC successfully handle a project such as this.

Re: Surface Loft with tangent constraints
I'd like to try this but need to know if it is possible to get this result using FC. I believe it should be.

Re: Surface Loft with tangent constraints
here my file. but something is wrong, it need to remake it from scratch.
