Hi thanks for your reply.
It is a sloping rafter connected to a concrete wall. I would very much like to figure out how to connect the rafter to the wall like i would cope it to a another beam in the top
thank you

use either another beam embedded into the conc wall. then cut geometry. then delete the beam.
or make plumb cut roof forms in the shape of the rafters.
and BTW whats the reason to draw rafters? isnt it gonna be embedded into a roof assembly? no one ever sees framing.
also your facia is done wrong. see how it doesnt miter.?

TO BEGIN WITH, YOU DONT EMBED RAFTERS INTO CONC. IN REAL LIFE, YOU WILL USE A LEDGER ATTACH TO THE CONC. WALL THEN ALL YOUR RAFTER WILL CONNECT TO THAT LEDGER. DRAW A REF. PLANE ALIGNED TO THE INSIDE FACE OF THE WALL OR LEDGER (IF YOU DECIDE TO USE ONE) THEN USE THE CUT TOOL.

Yes, in real life, it was dangerous.. I usualy drew my steel rafter connected to the concrete column like attached picture..
So.. if only for computer solution, for me, I will use face opening to make the end of the rafter vertical aligned to the wall..
Warchitect, plumb cut used for roof model isn't it? if broigutt use structural beam for the rafter, I think you cannot use plumb cut, isn't it? CMIIW
Maybe Manny's keyboard got damaged on his Caps Lock.. :D

Hi thanks for your reply guys
I am not looking for construction solution on the matter. I am an experienced Constructing Architect and have been working as a carpenter many years before that. On the pic i posted is missing steel fastenings bolted into the concrete. The beams are glue lam beams. what i needed as i said was to know how to cope the end of the beam perpendicular with the concrete. I extended them in this project into the concrete until i found a solution on how to cut them.
cheers

OK, Have you found the solution, Broigutt?
If not, is the sample I attach is what you want? if so, I use opening by face to cut the excess structural beam going through the concrete..

Hi vicozio
Genius ..! Worked like a charm thank you. One problem with this though is that the length of the rafter will not schedule correctly.
But ill try to find a way past this
thanks for your help.

You're welcome Broigutt.. ^_^
To tell you the truth Broigutt.. for structure modelling in Revit.. I haven't done anything beyond modeling.. so, I haven't done scheduling work for any structural element before.. :D Sorry, I cannot help with the schedule then.. maybe other will give better solution until the scheduling..

Change your walls to structural and then create a beam system. Select pick supports from your beam sysstem and check the box 3d in the properties. Then select your walls in 3d view to sketch your beam system and then close the system and your beams should stop at your walls. See attached.
