Splitting 3d polygons

[BenLeslie1]

Hello.

I have polygons in 3d.  I want to split them using a grid that is not 3d - is this possible?

Where splits are generated I'd like the z-value of the vertices to be interpolated between the z-values of existing vertices..... is this possible?

Thanks in advance....

Hi Ben,

As far as I know, it is not possible to perform overlay operations on features with different number of dimensions (2D vs 3D). If you need to preserve your 3D values, you'll need to convert your 'grid' to 3D features.

I haven't got ArcGIS at hand now to give you an example, sorry. Hopefully somebody else can.

Filip.
