How to create a profile with several sealings as a structural member?

See steps

  1. Step 1:

    This double profile done with sweeping but we need convert these 2 segments of a curve in spline.

  2. Step 2:

    I tryed the same double profile across a LFP sketch and only one profile can be extruded

  3. Step 3:

    Maybe you can connect all profiles with a bridge to get just one profile LFP.

  4. Step 4:

    Maybe if you absolutely must get feedback during the drawing, you could connect all profiles with a bridge between them so as to make a single profile. What I call "cheating". So if your concern is only modeling tool you scan multiple profiles and LFP cheated! But if you need when drawing a nomenclature of each profile with lengths and miter cuts, you should add to your structure (path) each profile one after another. Each profile having a common outline point to facilitate positionnment of each of them on this unique way. The dimensions for cuts would not be correct for all profiles, if you were a single profile LFP cheated!
