Hi everyone,

I’m having an issue importing the IG for the design shown below, where the middle glass is not at the same height as the interior and exterior glass. How can I add the glass and extend the middle lite upward?

I have attached the file here for your reference. Please let me know. Your help would be greatly appreciated.

Thank you.

You can edit the glazing system once it is inserted into THERM, and change the length of individual glass layers in the glazing system. 

In the Options menu / Preferences choice, go to the Drawing Options tab. 
Check the "Allow editing of IG polygons" box.

This will allow you to then select each polygon in the glazing system, and you can move points just as you can any other polygon, to change the length of each individual glass layer or cavity polygon.
