Combining three windows as one family

[Anonymous]

Hi,

While I was looking for triple windows,

I realized it is better to combine three windows that I have.

Two fixed windows and one operable casement window.

And I wanted to use this combination in the future projects.

Is there anyway to combine two or more families? 

I tried nesting families but could not get one.

Please advise.

All right

I found this help text from autodesk and I did it, finally

It's not so easy, but I hope it help me in my work time!

@ToanDN thank you so much once again
