at the moment I have created an extrusion along the path of 2 profiles that are parallel to each other (see image 1)
Is it possible to create in Revit an extrusion along the path between 2 inclined profiles to create a figure like image 2 ?
Thanks in advance
Yes it is possible : you can create a surface with
Surface.BySweep2Rails and then give it a thickness.
(and you can try some nodes which used a polysurface too)
