modelling in archicad

[keily]

hey everyone! im wanting to make an earthquake looking crack in archicad, any suggestions or thoughts on how to do this

thanks a bunch :))

Use a slab or morph drawn with the polygon method and then use solid element operations to subtract the ‘crack’ from the surface. Make sure the original surface and the crack are on different layers.

You could also use the OPENING TOOL, but it depends on the receiving Element type if you can apply it.
