surface by two rail and one profile

[paolo.campana]

Hi all, 

I have some trouble to define this kind of element,

It's a simple surface generated by two rail and a profile.

It's pretty simple by other software but revit seems not agree too much with this,

Which is the best way to define this kinf of surface in revit?

Thanks

If you insist on working in Massing Environment, you will need more than those 2 paths (circles) and that Profile (arc)...otherwise, you would be better of if you use a simple Revolve

having your elements as base I'd use the two circles from the bottom and from the top to create a Form and then to obtain the curve (generative) by creating an intermediate Profile , as shown in my screencast:

in fact what matters is to obtain the desired  result not the used method....

@paolo.campana  It does not work that way in Revit. You need two things: a) one reference line that works as the center of revolution, and b) the arc that you want. Then select elements a & b, and do Create Form.

Adaptive environment is different from the traditional loft with 2 profile tool. In this case you can try revolve as mentioned above or you define another circle in the middle and select all three profile to create your shape.

A simple revolve using an arc and an axis of revolution is also possible in massing environment...the question is though what is the ops intent...just a revolved profile or a little bit more than that
