Kowal Posted May 20, 2017 Posted May 20, 2017 The Civil 3D can create a surface with AutoCAD points. The image belove is a way to create a surface. How to create a surface using Lisp. To select points, I want to use the (ssget) function. Quote
BIGAL Posted May 21, 2017 Posted May 21, 2017 (edited) A couple of ways if you can go back 1 step use the import points option and save in a point group then make a TIN from that point group only. Is there a problem in picking the points, you could do some form of layer on/off using a lisp or Layiso which is built in. Lastly if you search down the CIVIL 3D 2014 directory you will find a example of how to create a TIN via a program, I will see if I can find it, something like Civil 3D API. I may have seen last in CIV3d2012. Search for c:\Autodesk\Autocad Civil3d 2014\sample\civil 3d api\com\vba\SurfaceoperationSample.dvb The other way may to use "-importpoints" need to check if it will accept a selection set.
