Is this possible in plain AutoCAD? Coz one of our PM requiring me to generate surface area of existing grade with provided point of elevation/location. And then extruded down with a level elevation to get an accurate estimated volume. Thanks for any response.
lots of work involved in doing it with vanilla. thats' where a real civil package comes in, Civil3d for one option. Carlson for a less expensive choice that _may_ be easier to get going with.
And along with the advanced tools comes more complexity. Unlike AutoCAD, trying to "jump right in" with Civil3D will lead to hair loss, forehead-to-monitor/keyboard contact, and various and sundry other conditions.
If a high level of accuracy isn't needed and there aren't a lot of points it can be done with a few steps in AutoCAD:
- break overall area into logical flat areas
- outline with POLYLINEs and extrude to depth
- get volume with MASSPROP or other methods
Thanks! I tried the LOFT command approximately connecting point with line to generate surface but its not looks good. I will ask the PM's for a Civl 3d CAD base. Thanks a lot.
You can also try the freeware utility "DTM" to create a basic terrain surface from 3D points. See http://www.cadstudio.cz/dtm

Hello from France
When I have many XYZ AutoCAD Points and I want to create a DTM, I used (since a long time ago) the "nice good old" Triangulate.vlx routine from Elpanov - THKS to Elpanov !
I have attached it to my msg ... This routine can run (on any ACAD/AA/MEP/MAP/CIVIL/etc x86 or x64) until a maximum of about 800 000 XYZ points !
I hope this routine can help you !?
