Hello all,

Today I'll share a tip from my colleague - Tomas Lendvorsky in EMIA

How to Create Civil 3D COGO Points in each Surface triangulation vertex

Objectives: We need to create COGO Points from TIN vertexes for stake-out

- Create a new Surface and copy the Surface to a new one using Definition-Edits-Paste Surface
- Create a new Style where only points will be displayed, and points will be displayed as dots (Points-Point Display-Data Point Symbol)

- Explode new Surface. (You will get ACAD Points)
- Set-up Create points Dialog
Prompt for Elevation Automatic
Prompt for Description Automatic
Default Description Something you want. (It will allow you to create Point Group later on.)

- Create Points-Convert AutoCAD points
- Create point Group etc

  • Hi Ove. Great tip! Another way and possibly a more appropriate process would be to EXPORT the Surface to LandXML. Open that XML file using the Autodesk LandXML Reporting utility (found in Start->All Programs->Autodesk->AutoCAD Civil 3D->Autodesk LandXML Reporting). Once it's open, select the FORMS tab, then Surface Report Forms and then select Surface Points in CSV. Finally, select the OUTPUT tab. A dialog should pop-up asking where you want the CSV file saved, save it. That file can be imported into Civil 3D using POINTS, CREATE POINTS, IMPORT POINTS. The only trick is that you'll either need a special format to parse the headers match the CSV & make sure it's setup to import PNEZ -or- modify the CSV without that data before the import.
