Binding a Beam to a Roof
You can bind a beam to a roof using a coincidence constraint. The beam will then follow the changes of the roof pitch. First, bind the beam's sideward location using a distance constraint, for example.

- Select Modeling | Connection |  Distance Distance   Coindidence. Coindidence.
- Select the roof.
         
- Select the roof surface.
         
- Select the beam.
         
- Select the beam line.
         
Note: 
    
  - The column under the beam will follow the beam, when a joint has been formed between them.
