Maybe I’m doing something wrong, but in curtain walls, when I use fixed cells for mullions + frame, the cells at the ends always end up being different sizes; the difference is equal to half the width and/or height of the frame. This doesn’t happen with supports.
Hi @XDGA can you share that file? Which is the Division type of your cell component?
The distribution of cells and muntins when the division type is set to Fixed number of cells, is done in a way to ensure the glass panel has the same size all over the curtain wall.
If your division type is “Fixed Cell Size”, then check the alignment. If the alignment is set to Bottom Center, the glass panels on the sides should have the same size, while the inner glass panels should have the same size too. I can’t appreciate from your screenshot from where are you taking the measurements.
Hi @fsalla
It appears wrong when using mullions and “fixed cell size, alignment center”, correct when using supports.
The measurement is taken in the axis of the mullions/supports. Glass appear to be different sizes indeed
attached a test file.

Hi @XDGA Thanks for the file. I see now the error. The two cells in the edges have different size and they should be the same. I’ll report it and get back to you when we fix it.
