[Qgis-user] 3D dxf files

[Matt Boyd]

Wow,
thanks Zoltan, I just saw this email this morning and this is exactly what
I was thinking I'd have to do myself.
I did manage to get SAGA to load the dxf, however I'd only made it as far
as being able to apply a value to each polygon, not each node.

I'll get onto this now.

Many thanks and much appreciation.
Matt
