Constraints and Links


I have tried to model a retaining wall. the retaining wall consists of a slab and a wall. I want to do a temperature analysis later.

Can someone help me by telling me how to choose the boundary if it is Line link or Line constraint or something else, and how to draw it.

If there is anyone offering or working as personal assistant, please contact me through my email:

Do you work with Revit, SOFiPLUS or…?
And what it the itention? Should only vertical loads be transferred from the wall onto the slab? Should the slab be supported by the wall? …?
