RaptorRidge Posted Sunday at 02:04 AM Share Posted Sunday at 02:04 AM 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 Sunday at 05:45 AM Author Share Posted Sunday at 05:45 AM 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 Sunday at 04:33 PM Share Posted Sunday at 04:33 PM 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 5 hours ago Share Posted 5 hours ago 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.
