Subdivide Polygon by Given Value
-
Hello. I am looking for a script that can split a flat polygon into a given number of equally-sized 'sub-polygons.' So, the script would take a flat rectangular polygon that and use an input to break the original polygon up into the input's number of equally-sized smaller polygons. I've seen the DivideByMaterial sript (http://sketchucation.com/forums/viewtopic.php?t=37719) and its close but not it.
The rationale behind this is that we have land parcels that have the potential to be subdivided (based on density, site constraints, zoning, etc) and we want to chop them up into their subdivision potential. Any help is appreciated. Thanks!

Hi Andrew,
Something like this? http://sketchucation.com/forums/viewtopic.php?t=42460

Thanks for your help Gai. (And apologies for the small font). That was close but not exactly it. TIG's tools are great but after installing them (including the Split Up) and the Quadralizer, I think the problem is that the polygons that I am working with are all irregular shapes (they represent land parcels). Hence the Split Up script isn't working on them properly. In the enclosed image
, for instance, I need to split this up into 9 equally-sized polygons. I can draw lines to divide them but we are going to be dealing with hundreds of polygons and that is not a time-efficient means. Any help is and has been appreciated. -
(Just to clarify) - In the above image - the red polygon is to be split into 9 equally-sized smaller polygons.

Since its for planning, I'm guessing there are lots of restrictions though? Does each parcel need to have access to the outer edge of the existing parcel (road access?) or maybe that would be covered by an access easement? Or is there a restriction that the dimensions should try to be fairly similar on a length x width - ie no parcels that are all 200' long by 2' wide.
Its the subtleties of the script that make it a little more difficult. But if you can define your needs more precisely, it would be a good script to write.

Chris,
You are indeed correct there are various restrictions, setbacks, and access requirements that make the desired end-product less than perfect. However we are going for something rough here -- We have the mother polygons and the subdivision potential for each - we need to divide the polygon into even sized by the subdivision potential.
Our thought is that if we have equally-sized polygons for each 'mother' parcel (original polygon), we can use a Greeble script (or other) to plop a simple 3d house structure into each parcel, export to Google Earth, and have a rough visual image of what agricultural/forest land could look like if subdivision proceeded. Right now, we have used fly-overs in Google Earth just showing highlighted polygons (exported from ArcGIS) that have the potential to subdivide. It would be better if those polygons were split and a simple house was there in its place.Any help is appreciated.
