Generating TopoSurfaces

Tried creating toposurface by specifying point elevations. It seems the surface is always created from a certain absolute level irregardless of how I try to move or respecify the Project Base Point.  Am I missing a certain setting?

 

Thanks for your help.

That's fine, I got that.  My problem is:  a point elevation of say 20000.0 should generate a point on a surface that is 20000 from the Project Base Point elevation of 0.0.

 

My problem is, no matter how I move the project Base Point, the 20000 will always generate a surface at the same level if I move the Project Base Point.

 

 

Thanks.

Did you clip the Project Base Point?

Yes, I tried both moving the PBP and SBP clipped and unclipped to see the effect on the generated surface.  The surface is always generated on the same absolute level.  Also, when I start creating a surface, I'm getting only the 'Absolute Elevation' option.

 

As a work around I mark this position (0.0) and physically move the surface to where I want it after.  That's not ideal or correct.

 

 I've been generating surfaces before without any problem,  I thought there may be some settings I'm not aware of that changed that I'm not aware of.

 

 

Thanks.

I asked you about the clipped PBP because I thought you need to move the PBP without moving the topo surface.  But it wasn't the question.

 

It's always been as you described as far as I know.  When you create the surface, if you don't select a Work Plane, it will default to the View's Level.  So, you can add a Level and the level's View prior to creating the surface and draw the surface on that View.

 

The recommended workflow would be create the topo surface in a separate Site file, establish Shared Coordinates, and linked in the model file.  Then the model file acquires the Shared Coordinates from the Site link.

Thanks,



I agree with the link file.



This particular one was a small surface created on a site level off several meters from the PBP. When I generated the surface it didn't went to the correct level so I started several trials moving the PBP(unclipped), still it went back to that level no matter where the PBP is. I thought there was a reason for it to do that.



Thanks for the help.
