Add a Ground Level Line to an Elevation View

You can edit the elevation views generated from the building model by adding a ground level line to the elevation view. In the final elevation drawing, the part of the foundation left under the ground level line can be completely hidden or drawn with a dashed line. This can be accomplished by drawing the line on either of the following layers:

• 93 Dashing ground line
• 94 Clipping ground line

Note: A terrain added to the building model does not form a dashing or clipping ground line. Hide the terrain model from the elevation views by adding it to a hiding group. Check in the drawing generation model settings that visibility by active hiding groups is selected.

Add the ground level line in the following way:

1. Open the desired elevation view into a separate drawing window. Use either of the following tools:
   • If you haven't created the elevation drawing yet, open the view with the function Update Views.
     • Select the view in the Views list box of the dialog box.
     • Select the check boxes Update views and Update models.
     • Select Drafting as the opening mode of the view.
   • If you have already created the elevation drawing and the drawing sheet is open in the workspace, you can open the view with the function Open a View Drawing from a Sheet.
2. Add the ground level line to the view. Select the Polyline (2D) function.
   • Select an appropriate line type on the Properties tab.
   • Select the layer on which the line is to be added.
     • If you want to display the foundation with a dashed line, select the layer 93 Dashing ground line.
     • If you want to hide the part of the foundation left under the ground level line, select the layer 94 Clipping ground line.
3. Click the line points.
4. Close the drawing window and save the changes.
   • If you opened the view from the elevation drawing sheet, close the drawing sheet as well and save the changes.
5. Update the elevation drawing with the function Update and Open a Drawing Sheet.
   • Select the elevation drawing in the Sheets list box of the dialog box.
   • Select the check box Update views.
   • You can clear the check box Update models, if you haven't done any changes to the building model after creating the elevation drawing.
