Converting numbers to geometry

I have a data set with numbers in x y z sequence separated by "," representing 3D geometry polygons and points. It was originally WKT and had been formatted to work with Dynamo (Revit).

 

Here is a sample of a point:

841.99951171875 678.6250000000001 -132

 

Here is a sample of a polygon:

409.000000000001 473.499999999999 372,409.000000000001 797 372,487 797 372,487 871 372,1275 871 372,1275 476.286679607417 372,1275 461.500000000111 372,409.000000000001 461.5 372,409.000000000001 473.499999999999 372

 

My hunch is to chop everything up into x y z attributes and then reconstitute into points/polygons. Using two AttributeSplitters, I can create a list, but then, how do you assign these numbers to x y z in sequence? It is so close to WKT, maybe there is an easier way?

 

Thanks,

@larue​

Hi @larue​ 

You could try using an AttributeCreator or AttributeManager to format your data as WKT and then use a GeometryReplacer.

 

For example, with the point data, insert POINT ( in front of the data and ) after to create

POINT (841.99951171875 678.6250000000001 -132)

 

This value can then be used in the GeometryReplacer with the geometry encoding as OGC Well Known Text.

Nice job @debbiatsafe​
