Catia V5 Thicken surface no assembly


I am trying to get a solid from a surface with thick surface and apply constraints in assembly workbench. The problem is that those constraints are not allowed.

1- I revolve an edge around an axis and then I apply thick surface. Now I can apply constraints. (The pictures upside)

2- I make 4 sketches. Blend, blend, blend, Healing + join + thick surface
Now I can't apply any constraint in assembly workbench

What is the problem with the second option?

Blend is not mathematicaly circle or cylinder.

Good morning özgür kesebir,

Thank you very much for your reply.

I don`t understand really good. If I apply blend between those two circles, what I am building with blend? Am I not building a surface with circular form?

But then I can not use it with thicken surface in assembly?

Yeap you are correct. Blend and multisectionsurfaceturns surface Curvature mathematic. You must use Extrude for creating cylindirical surfaces with axis.
