Ok... I have been racking my brains and can not figure this out. I've gone out and topo a site. Start carlson survey 2011 for CAD. Import the points. Build a surface through surface> Triangulate & Contour. Everything looks great. Simple site. But when I go to put in a new point, I don't get any elevation when asked for the Z value for my points. So I tried to do a spot elevation and come up with no elevation. What am I missing?
In ACAD, you have to turn on Elevations in the Point settings.
Maybe something similar?
:coffee:
I use 2011 with intellicad...
Under Points/Point Defualts, I check "Locate on Real Z Axis".
I thought I tried that, but I did it again. "Elevations" was checked and I checked "locate on Real Z Axis". Then went to points>draw-locate points>draw all. (I believe all that does is add elevations to the points and puts them on the actual Z axis instead of zero). So Then redid the surface from scratch under surface> triangulate and contour. Surface looks fine. Countours lines are on different z values. I then go back to points>draw-locate>screen pick and pick a point anywhere on the surface and it asks me for the Z value instead of giving me a value. Then tried a spot elevation and same thing, no z value.
I do have a support ticket in with Carlson and they are communicating, but seeing who can help me solve this faster.
As I recall, the feature you are looking for is under the Surface menu. When you create the contours you need to save a .tin file. Then under Surface/Spot elevation there should be a draw spot elevations by surface model. That should allow you to place points where ever you want on the within the area you contoured and automatically give you the elevation. The menus might be named differantly, I'm looking at 2010 on AutoCAD right now.
I apologize if this isn't helping.
But, in (my) ACAD, It's Set Random Point. If picked within the surface (TIN) it will place a point with the projected elevation.
All CAD packages do the same thing, sometimes I throw this stuff out there to just to see if I can help in the thought process.
Carry on.
