Inserting a local reference surface in a plane model

You can use the Planes palette to insert local reference surfaces in a plane model of the current building structure. The reference surfaces you want to insert must be saved in a drawing file. After you have inserted a reference surface in a plane model, the reference surface is no longer linked with the local reference surface. If you want to apply changes in a local reference surface to the plane model, you can replace the reference surface quickly and easily.

To insert a local reference surface in a plane model

• You have already created the local reference surface; the drawing file with the reference surface is current.

1. Open the Planes palette.
2. Switch on Modification mode.
3. Click Insert or replace reference surface.
4. Select the structural level in the plane model to which you want to add the reference surface.
5. Select the reference surface.

   Allplan inserts the reference surface in the plane model, displaying the name of the reference surface in the Planes palette.

6. Click the symbol between Height and Name, specifying how to connect the reference surface with the upper or lower plane of the structural level to which you have added the reference surface.

   Click the symbol to toggle between the following settings:

   • Do not connect (default setting)
     Changes to the upper or lower plane of the structural level have no effect on the reference surface.
   • Connect with bottom level
     Connects the reference surface with the upper plane of the structural level. When the upper plane moves, the reference surface will move too. Consequently, the distance to the upper plane does not change.
   • Connect with top level
     Connects the reference surface with the lower plane of the structural level. When the lower plane moves, the reference surface will move too. Consequently, the distance to the lower plane does not change.

     Note: To display the original state of the plane model in the Planes palette, click Update model.

7. If you want, you can make more changes to the plane model.
8. Click Apply to save the changes in the plane model.
