No push pin

[silverlance360]

I'm trying to put a curtain wall door in a curtain wall..
For this you gotta unpin the glass panel where you want to make the door right? (as i saw in an instructional video)
The pin button is not even on the modify ribbon as it should be.. a problem with my software?
Thanks

When you select the panel or mullion, it should have a push pin at the end of a leader attached to the panel/mullion (if the panel/mullion is defined in the type properties of the curtain wall).  If it's unpinned, you will be able to swap it out in the type selector (as it appears you can in the image you posted).
