welcome to the world of Revit curtain wall madness

there is no reason to create a curtain wall by face on a mass to get segmentation in plan. Revit does have it's idiosyncrasy's when creating curtain wall. The head section being continuous on the right is how Revit creates curtain wall when a profile is edited to have a sloped top. If what is shown on the left is what you want to end up with you have a long arduous path ahead of you. For 2D views I would use masking regions to fake the look you want. If you need the correct configuration in 3D views then you are going to have to create generic models of curtain wall mullions and head horizontals to replace the standard curtain wall results. It's a path to much pain I can tell you.

There seems to be some other funky stuff going on with your curtain wall, like vertical and horizontal mullions not created from profiles having the same shape/dimensions. I didn't look at your attached file so don't know exactly what's going on but it's not normal Revit curtain wall results that I'm seeing in your screen shot.

And, about the corner mullions for your segmented divisions, there are a lot of threads here about this subject. My preferred method is to use a parametric generic model for a corner mullion. Revit doesn't like to make curtain wall segmented corners from standard mullion profiles.

Tnx for your answer.
About your 1st answer. Now I draw a standard curtain wall (flat part, beneath) and the top with "edith Profile" on the curtain wall to create the top.

But how can I to replace the highest transoms with generic model transoms? The generic model transoms don't snap at the highest point the transom.

Kind regard,

curtain wall terminology 01: the curtain wall part that you are describing is referred to as a "head" (at least in the USA). A "transom" is a horizontal member over a door that has glass/panel above. To your question: make a work plane based generic model of the profile of the curtain wall head and have parametric length and end angles (different for each end while you're at it to cover all situations for later), then create ref planes in your project where you need them to be and create an instance of your GM using the Place on Workplane option. Adjust the length and end angles as required. Making the GM family correctly will take some time and an understanding of family creation. If you are a beginner you are apt to be worrying about appearances a bit to much. Just out of curiosity why is the look that you want so important to you? What is your end result to be used for?
