Beam placement and modelling on BEAM SYSTEMS

Hello everyone 

 

I'm modelling a whole bunch of different roofs and their wooden structures for an important project in my company and I would like to know why is it when I create a beam system the beams on the end corners are not created?

 

I can get around the problem by placing two extra beams manually but I don't like that. Am I doing something wrong?

My other question is relating to how the beams interact with walls and other geometry.

I recently learned how to cut geometry and model a single beam on whatever shape I like, but what about the beams that are created through Beam Systems? Would I be able to model the end corners of my Beam System to match the roof's fascia and walls?

Beam Systems are very nice but they have their limitations. For the end beams, simply draw your side boundary lines a little further out than the end of each roof, then place the Direction Line (when sketching the beam system boundary) where the first beam in the set will be located. If the roof length is a precise multiple of the spacing, the end beam should be located at the roof edge also; if not, the last beam will be placed near the end. Then you can adjust as necessary.

As for the front and back faces of each beam, place a reference plane parallel to the wall then use this reference plane to cut each beam element (or use a Grid if it's in the right location; the key is to find a datum element). There is no way to cut all of them at once, but selecting the Multiple check box when you are using the Cut tool can make quick work of this.

If the rafters are hung from a ledger board, which is fairly typical (if not code), then you could use the Coping tool (CP) along with a 0'-0" Coping Distance to cut the rafter flush with the face of the ledger.
