Creating concrete and steel slabs

[Ferdissss]

Hi! 

In Robot Structural Analysis, I want to create a steel and a concrete wall/slab. I have heard that you can use contour to draw the area, and then change the thickness and material of it to what you want to create a concrete/steel wall. I tried this, but the mass of my structure and the deflection doesn't change, so I guess it is still a cladding? How do you then create a wall, can you only do it by changing the geometry to 'Building design', and choose wall?

No.

On panel geometry dialog ,click on parameters button and then mark it to be a "panel" instead of "cladding" or "opening"
