How do I create 3d faces to export DTM to Topcon GPS for uploading into earthmoving GPS controlled equipment?
I have tried visualising triangles to 3d DWG file but it creates a Mesh of triangles rather than shapes?

G'day Matt,
I can offer a couple of suggestions.
1) DTM>Utilities>Export DTM. There is an option to export the DTM to a Topcon TN3 file. I believe that this is the machine control data file that can be imported into Topcon machine control equipment.
2) If you follow the Export DTM Triangles to DWG. Can you then use the Drop Element>Complex tool to drop the mesh element back to a series of triangle shapes.
One of these should provide a solution I hope,
Michael
Hi Michael,
Option 1 sounds good (i will give that a try).
Option 2 - i have tried this and it creates shapes fine, but then when you export this to dwg it converts back to a mesh (which 3d office does not like?)
Thank you
The DTM export to Topcon.TN3 worked beautifully the only problem now is how do i import the linework into 3d office (i.e BOK, CL, block boundaries, the TIN file conversion to TN3 gives triangulation but not the linework?
Thanks
Hi Matt,
Reading your original post, it appeared as though getting the 3D faces was the desired result.
LandXML export should provide the DTM breaks and spots etc. Assuming that the Topcon software supports LandXML import - that should solve the problem.
DTM>Utilities>Export to LandXML. That should provide all the DTM features and the triangle faces.

Now... if you want specific graphical features out of a Modeler design (and not ALL breaklines and spots from the DTM), you could export the 3D elements from Modeler into a DWG file. I believe I saw you menation that the Topcan software can import data from a DWG?
1) You would need to create a DWG file.
2) Reference your Modeler DGN file
3) Open your Modeler project (answer "no" to the message about a different file name)
4) Project>Export>3D Elements.
5) Set the filter to find/create only the elements from the Model that you want.
6) Export the elements. They will be written to the DWG as 3D elements.
Will that help??
Option 2: I tried this.
1) Dropped the mesh in the DGN.
2) Save Settings.
3) Export to DWG.
4) Open DWG in PowerCivil.
5) Info on the trinagles and they are shapes (not mesh).
Seems to work as expected.
