This are 2 tests that I made and I notice that B and T values are the values that I put on zshift and height... But this don't indicates nothing about the plane... how can I reference the sea level plane? I am a little lost here haha.Tnks,Alec

What does v.info say?

'as 3d' is selected. I have 83 boreholes and all of then have their base on the same plane, and it shouldn't be.Tnks,Alec

Hi,
there is a switch in the 3D view vector gui to switch between displaying as 3D and on a surface. You might check if that could be the problem.

Hello folks, I am trying, again, to draw some 3d boreholes, I was able to draw then but when I was analizing my results I notice that all my boreholes was all with the same z value, which is strange since I have different zshit and height values for each of my boreholes. So I guess i missundestood the zshit value. I need 3d boreholes that are draw from different levels (different Z coordinates) and of course with different sizes (heigths). Is there a way to do this? what I am missing here? I was back to Gene implementation:

But then I realize that they boreholes are at same plane too, just don't appear to because of perspective.I appreciate any help.[]sAlec Ventura.
