Create form from Mass intersecting line

[jagostinho]

Hello,


I was looking on how to create a vertical Form that would pickup from a waving line both horizontally and vertically.
I would rather to use a Reference Line so that I can change the Form shape easily in the future but whenever I select Pick Lines the RefLine ends up flat on the 2D workplane.


I was wondering if there was a way to create a form by selecting an intersecting line as a result of a main mass cut by 2 void forms.


Please see image attached. Target line highlighted in yellow.
I also send project file attached with mass.


Any feedback is mostly appreciated as I am a begginer in massing.

Yes, you can obtain the projection of that line on another plane, and use that resulting line (spline, actually) to generate another form. Set a workplane. Then use the spline tool, and the pick lines tool, and click on that edge. You will get a projection of this edge on the plane.

That could work, but the intersecting line waves in 3D, meaning, in all X, Y and Z axis.
