Convert DTM Elements to 3D

Task area Terrain Model

You can use this tool to convert DTM elements to a surface model or solid.

To convert DTM elements to 3D entities

1. Click Convert DTM Elements to 3D (How).
   

   Activate Convert DTM Elements to 3D in one of the following ways

   • Menu bar: Create Terrain Digital Terrain Model

   • Palette: Tools Create area in the following modules:

   Digital terrain model

2. Select the number of the destination file for the new 3D elements.
3. Click Surface in the input options to convert the DTM to a surface model. Otherwise, click Solid if you want to make a volume model.
4. Click the DTM to be converted.
5. Specify the horizon (solids only).
   The value of the horizon must be smaller than the minimum height and greater than the maximum height of the DTM.

Notes:

• Only the actual mesh structure of the DTM is converted. Additional elements like contours, for example, must be copied using Copy, Move Elements between Documents. The association of the elements with the DTM is retained. To copy them as discrete elements, use Convert DTM Elements to 2D.
• Recesses are modeled as boxes in the 3D solid; break lines are modeled by the respective surfaces.
• When you convert mesh structures with more than 2,000 points, these structures are divided into several separate 3D elements (each up to 2,000 points). You can combine these 3D elements to make a group that can be addressed as a single entity.
• All special lines will be lost when you convert back to a DTM from 3D using Convert 3D Entities to DTM.
