How do I get split/comp rules to align properly with the world.y extrusion after having the building on the terrain slope?

Hi there,

I have been creating a cga rule for some buildings without aligning it onto the terrain. Therefore I was working on a flat slope and the buildings turned out great.
After it has been align to the terrain, the buildings started to look weird (see attachment) and I'm not so sure how I should get it nicely aligned again.

The extrude function has been changed to world.y but the components and splits still isn't right.

Hi,

the easiest solution is instead of projecting the shapes to the terrain, use the translate option in the same tool.

otherwise, you can also use

Shape -->

alignScopeToAxes(y)

s('1,0,'1)

to flatten the footprint before extruding.

and / or make sure you use extrude(world.y, height) instead of extrude(height) in such cases.

Cheers!
