Integrate unique shape

TadeoSanabria2 — Wed, 05 Dec 2012 12:18:52 GMT

Hello
Try to model the regulations of the urban plan of a city, but I have two problems:

1. delimit public transfers of urbanization, if I use the rule:

Cession ->
s (side of the rectangle, 0, side of the rectangle)

Not how to become a complement to correspond to the footprint. I think it could subtract the original scaling the result of the rule, but not how.
Any idea?

2. if I use the rule:
Cession ->
setback (sideCession) {back = Lot | left = Lot | remainder: CessionEP}

CessionEP ->
extrude (1) color ("# 80FF00")

Lot ->
color ("# 80FFFF")
setback (AislamientoPosterior) {back: Post | remainder: Cuerpo0}

In this case I can´t integrate the lot in a single form. There are some instruction that allows me to do this?

Thanks. Insert Image

Hi !

Sadly, you can not split and the rejoin the resulting shapes yet in CE.

So you'll have to find a proper series of splits which results in the geometries you'd like.

This can indeed be tricky to code, I'm currently thinking about parcel subdivision in CGA a lot too !

Try working with setback(), shapeL() shapeO() shapeU() and split(), together with different aligns.

Let me know if you're stuck somewhere !

Thanks matthias

I Tryed to set the new geometry and follow your recommendations. excuse my bad English

can I use Boolean operations with shapes ?
eg intersection, union, subtraction. through which instruction?

Hi !

Sadly, also no booleans available. You really have to split the geometries in the order you need them.

Of course it can be that some things are not possible.

It' d be best you post a quick drawing of what the input geometry is and what your target geometry is. Then I may have some inputs for you.
