RaptorRidge Posted January 19 Share Posted January 19 Hi all, I know this has been asked before, but I couldn't find any solutions in all the old threads I found. My surveyor sent me the attached files which I have been trying to import as terrain in CA for hours now. I've gone through all the videos online and I can import it just as a CAD file fine, but then when I try to map the contour layers to terrain info, I get nothing. I then tried using the csv file, but the X and Y numbers are way off compared to the Z which seems correct in feet? I would much appreciate anyone who can point me in the right direction! 4220-01 Existing Conditions 20250117.dwg 4220-01 Topo Points.csv Link to comment Share on other sites More sharing options...

RaptorRidge Posted January 19 Author Share Posted January 19 Yeah, that's what I've been trying, but when I assign the cont-minor and/or major to terrain data, nothing shows up. Link to comment Share on other sites More sharing options...
scottharris Posted January 19 Share Posted January 19 Importing terrain dwg files can be an effort if you do not know how the surveyor mapped the layers -and- if they have all the data. I successfully imported your dwg file; it appears that the ‘V-PROP-BDY’ is your permitter; it well extends past your CONT-MAJOR / MINOR lines. I did not see any actual elevation data in those lines so it’s a flat lot. You might go back to the surveyor and see if they can re-export the file.

JiAngelo Posted January 22 Share Posted January 22 The 3D data is in the DWG file. You can see it using TrueView's Named Views or 3DORBIT command. The data is locked inside of a cad block on C-TOPO. To test this, If you import only C-TOPO you get nothing. If you import only CONT-MINOR and CONT-MAJOR you get nothing. Importing all 3 gives you the contours inside a CAD block with no elevation data. There appears to be blocks on other layers as well, and there is no boundary polygon to import as a terrain perimeter. Have your surveyor resend the DWG unblocking the CONT-xx layer contours.
