Hi,
Based on the picture it looks like that you have saved the diamond-shaped frames and the checkerboard patterned panels as a single custom panel. Since these panels are not properly GDL scripted (just static geometry), ARCHICAD can't trim it's edges (it has no instructions what would be the proper way to do so), it will just place it between whichever frames you place it between. This means, it will shrink them into the smaller areas (that's what happens where they are distorted), and they just extend over diagonal boundary frames (since ARCHICAD doesn't know to trim them, it can't override "user intentions").
I would suggest you to place the CW with a checkerboard pattern, and draw diagonal frames manually instead (so you can reach the same pattern with stock panels and frames).
