I see. Thank you for your help.

The code should reproduce things as the posted image. Works for me... Thank you, Carlo and edwilliams16. Once I restarted FreeCAD, it worked. I don't know what was wrong. Am I right in understanding that this method is equivalent to the workaround in my post below except that it is automated? https...

The animated gif shows the steps to take ... Thank you for posting the animated gif. It works quite well as long as boundary curves are independent curves. Once the boundary curves become a part of another surface, it causes an error without any error message as shown below. Do you have any clue wh...

Hi snow54, greetings to the Community! Using the Wb "Surface" the result in the attached image, but I don't know if that's what you were hoping to get, in any case the modeling flow file is attached. Hello! The result looks very promising. I have been trying to reproduce what you have don...

Probably found a solution. https://forum.freecadweb.org/viewtopic.php?p=618994#p618994 Thank you for finding the solution. I have downloaded the script you created but I have been struggling to reproduce the upper geometry in the capture you have in your post. Do I have to do something other than r...

Thank you all for your additional replies. The only way to do this (from what I know) is by degree elevation and knot insertion. This will compute new sets of control points without changing the shape of the curves. This will guarantee that the ruled surface matches exactly the input curves. But thi...

Thank you, Chris_G and Carlo for the additional advice. I understand it is not possible to change the internal parameterization of the curve itself without changing its shape. However, I don't understand why a ruled surface has to follow that. There could be many algorithms to connect two curves. Fo...

Thank you for your quick reply. The method you suggested worked nicely to create a surface but alters the original curves. I need to use the original curves because those are the edges of another surface that I use to create a solid. Altering the original curves voids watertightness of the geometry ...

How can I create a smooth ruled surface between two spline curves with different control point spacing? When spline curves have varying control point densities along each curve and are used to create a ruled surface, FreeCAD tends to connect parts of the curves that have denser control points. It so...

Thank you for pointing that out. I was still using v0.19. That explains.
