Converting a 3D surface to a reference surface

Using 3D surface to reference surface, you can convert any 3D surface to a reference surface, giving this reference surface a name of your choice. You can use a reference surface to define the height settings of architectural elements. In addition, you can insert a reference surface in a plane model.

To convert a 3D surface to a reference surface

1. Right-click any 3D surface and select 3D surface to reference surface on the shortcut menu.
2. Enter a name for the reference surface in the dialog line and press ENTER to confirm.

   The reference surface gets the format properties currently set in the Properties palette. Allplan saves the reference surface in the drawing file.

3. Select and convert more 3D surfaces or press ESC to quit the tool.
