To Create AutoCAD Solids from AutoCAD Civil 3D Pipe Networks and Pressure Networks

1. If your drawing is currently in plan view, change to a 3D view of the drawing.
   Note: If your drawing is in plan view, a dialog box will be displayed after you select the Create 3D Solids from Pipe Networks command to inform you that you may obtain better results if you switch to a different viewing direction.
2. At the Command line, enter ConvertTo3DSolids.
3. Select the pipe network and/or pressure network parts and press Enter.
4. Enter No if you do not want to erase the selected parts, or enter Yes to erase the selected parts.

   The solids are created in the drawing on the same layers as the selected parts.
