Revit corner mullion issue

[526996629]

Any way to create the corner mullion to the red region in the image?

Can you provide a little bit more information?

[526996629]

Mullion 2 is connecting the straight curtain wall and the curved curtain wall and it is supposed to be in the middle of the connection location of the curtain panels. So I am wondering if there is a quick way to directly adjust it. Not sure if this is clear

Why don't you disallow joins and overlap them?

Thanks mate. But this is not a good choice for me to overlap them cuz we need a model to calculate all materials and I would prefer to make the model more accurate rather than making it 'look good'. If there is no good ways at the current Revit version, I would just delete the mullions at the corners and manually model a component.

HUH? I'm just calling it like it is in your screenshot, Mate. The mullion is clearly overlapping.  No?

Maybe posting a screenshot of what the actual condition looks like in real life would be better.

I'm guessing like this? Real life & shop drawings

When curtainwall is at the edge, the rectangle mullion will always placed at the end and will not placed in the middle of the mullion. If you want to force the mullion to go into middle, you have to create custom curtain panel family with built in mullion that will placed in the center or you use one of the system corner mullion.

There are a couple of approaches. 

Create a Solid Mass that shape, Divide the Vertical Surfaces (no U grid) and use a Rectangular Pattern-Based Curtain Panel that includes glazing and Mullion geometry. 

or Basic Wall by Mass Face for the Glazing and 3D Beams for Mullions.

What's the issue with overlapping mullions? I did the math using your dimensions and it's a 1/8" ± overlap. Minuscule at best. 

 

Reference:

The minuscule overlap can be removed by simply cutting it off. If you used Structural Framing to create those curved Mullions, you can quickly and easily cut back the ends of those Mullions to the Ref. Planes where the Curtain Walls begin/end. Press Cut Geometry, select Mullion and then select the Ref. Plane.  Bada bing.
