Command Description
The 3D Object From Surface command enables you to select a surface and apply a depth and/or surface offset against it. No boundary is required, however one or many closed boundary strings can also be applied to create a 3D solid object.
- Click in the Surface selection field and select the surface.
- Optionally select one or more closed linestrings to be used as boundaries. Click Options button for additional selection options.
- Pick a Mode from the list:
- “Depth” will apply a value from the surface to create the solid. A positive number applies in a downward direction and a negative number will be applied in an upward direction.
- "Elevation" will project the surface up or down to an entered elevation.
- A vertical Offset can be applied to the original surface. A positive number applies in an upward direction and a negative number applies in a downward direction.
- Enter a BIM Group name for the new object. This will be saved in the project explorer under the BIM Data.
- Enter a Name for the new 3d object.
- Select a Color for the new 3d object.
- Select or create a Layer for the new 3d object.
- The Chord tolerances are applied when using linestrings that contain curves.
- Horizontal – This applies to horizontal curves.
- Vertical – This applies to vertical curves.
- Do either of the following:
- Click Apply to create the 3d solid and keep the 3D Objects From Surface command pane open.
- Click Close to end and close the 3D Objects From Surface command pane.
Tips: Sometimes the 3d object created is not formed correctly from the surface. This can often be fixed by one of the following methods.
- If using an imported surface, try recreating the surface in TBC using the original surface as the member.
- Use a boundary string with the surface.
- If using a boundary, use the Line Node Clean-up tool to make sure the boundary string is clean.
