Sometimes you get just a Tinn from a survey to get points for the vertices you can use the lisp routine call 3DF_to_3DPoint that you can download from here
Download the file type appload at the commandline in Autocad and then load this file and type “3DF_to_3DPoint”
You will get a whole lot of points but there will be 3 at each corner you how have to use DataExtraction command to export to a text file the xyz of each point and then remove the duplicates in Excel and re import the points as Civil3d points.
Could you not turn on Edit Triangles style in the surface, and then extract the points? Then Convert From AutoCAD Points (CREATEPTCONVERTADESKPTS)?
ReplyDeleteOr is this from an entirely different type of TIN?

ReplyDeleteThis was just a tinn as 3dface objects from a contractor. I guess I maybe able to have done it with your workflow will try it out next time.

I guess you'd have to create a Surface from the 3D Faces first, for my workflow.
ReplyDeleteHope it all works out for the best, no matter which route you choose. =)
