Hi everyone!

I have several building models in WGS84 and heights relative to WGS84. How can I clamp those buildings down to WGS84 so that they can be visualized on the surface of WGS84? In other words I need to get rid of the heights!

Thanks in advance!

IF you have a 3D feature and you need it to be 2D then the 2DForcer is what you need.

Maybe 3DForcer with an elevation value of 0 would be better ?

I do not want it to be 2D, I need my 3D model to "land" on WGS84 surface instead of hanging several meters above the surface.

3D Forcer it is, thanks dude! But not with elevation value of 0, but I have feature's elevation as an attribute. So by using arithmetic functions it is possible to do that.

Now I am gonna use 3DForcer to reduce Z values of all points of a feature.

I have a MARK_Z value attribute and need to use Arithmetic Editor so that resulting z value becomes as z - MARK_Z. (z value of every single point of a feature minus MARK_Z attribute of that feature)

But I cannot get current z value in Arithmetic Editor. Any suggestion?

you can try the @ZValue() function in the Arithmetic Editor
