My buildings extent are not exactly rectangular (static shapes)

ThibaultThibault

Hi,

I imported some buildings extent interpreted by CE as static shapes, but they are not perfect rectangles.

So every time I attempt to use a split(x/z) or a comp(f) followed by some t(x,y,z), it is all messed up.

Example using split :

General view	CGA
	version "2014.0" @StartRule A -->     extrude(6)     B B -->     split(x){         0.5:P|         ~1:M|         0.5:P} P -->     color("#FF80C0") M -->     color("#00FF00")

Example using comp(f) :

General view	Issues
The yellow face is the "front" face of the ground floor, translated backward.	On the left it overshoots On the right it undershoots

I guess my problem is that all my operations are based on the scope of my model, which is rectangular, but my shape, so my model, are not.

What would be the best way to handle this ?

Thank you.

I see whats happening - your Transformation command t(0,0,-corridorWidth)is shifting along the Z-axis of the shape - so straight back, but that "straight back" is not aligned with your object since - like we know - your shape isn't square.

What I have done with the code below is isolated your ground floor - then split off the corridorWidth with a NIL so its gone. The result should be what you are looking for - on the left...
