Corner window - Help required!

[Zack2016]

I could not find a similar thread. Sorry if this is a duplicate.
I am in the need for a simple corner window family that has these requirements.
I cannot make families yet. Sorry...

Width of two sides adjustable independently of each other.
Single glazed nothing fancy.
Glass joins in the corner without a frame, simple silicone joint.

I have tried several. Either the width is missing or the corner silicone frameless joint is missing.

OR

I have one that is very close from revit city. <Attached below> It has a simple join and adjustable width on both sides.
However the void it cuts on the wall is adjustable for one side the other side is fixed.
I need the void cut to be adjustable or make it such that it can cut a 250 wall on both sides.

Any help would be immensely appreciated.
Thanks

You have a few options Zack:

1 - use one family, but place it twice, with a fixed offset (probably from the internal face of the wall) and the mitre cut/joint as part of the family. This is potentially messy, but if you need to schedule the window as two separate elements, by far the most straightforward for documentation.
2 - check the cuts with voids when loaded box and add a void to your family that has the corner window fully modeled. Less messy than option 1, but scheduling may be an issue.
3 - use curtain walls. Again, not ideal and you'll run into issues with tags etc, but by far the simplest solution from a modeling pov.
