Extrude surface

How about exploding it (if it is a solid) and aquiring the bottomsurface (by z =0)?

 

 

 

If its not a solid, just extrude a bit, then explode then aqcuire bottom.

Hi,

 

 

You can use "Vector" mode as Extrusion Input By, and set an appropriate negative value to Extrusion Vetor Z.

Thanks, but cant find any way to extrude a TIN surface. Works fine with triangles etc but not surface

Combination of the GeometryCoercer (Geometry Type: fme_comoposite_surface) and the Deaggregator (Split Composites: Yes) can be used to decompose a TIN surface into individual triangle surfaces. And then, you can apply the Extruder.

Thanks Takashi,

 

It works to extrude them when they are splitted but still cant find a way to extrude them down to 0. The extruder only allows me to extrude to a value and since its triangles with 3 different z:s it still doesnt give me a fim base.

hmm, I was able to extrude the surfaces to negative direction in both these cases.
