Excavation

The excavation is defined with a contour. Several excavations can be defined in the same project.

Workshop

1. Switch the "without structure" storey to active and hide the top floor.
   
   
2. Start the TERRAIN function and then the EXCAVATION function. Ensure that the type of entry is set to "Drawing the contour".
   
   
3. The drawing functions appear in the Input assistant. Switch to the drawing function RECTANGLE.
   
4. Draw the rectangle using the two points P1 and P2.
   
   
5. Enter the values into the excavation dialog and confirm with .
   
   
6. Start the terrain function and then the EXCAVATION function. Ensure that the type of entry is set to "Drawing the contour".
   
   
7. The drawing functions appear in the Input Assistant. Switch to the drawing function POLYGON.
   
   
8. Draw a contour from point P1 – P7.
   
   
9. Fill-in the values for the second excavation and confirm with .
   
   Tip

   There are 3 different display methods for the terrain.

   • TERRAIN MODE - WITH STRUCTURES
     
     
     
   • TERRAIN MODE - WITHOUT EXCAVATION (REFERENCE TERRAIN)
     
     
     
   • TERRAIN MODE - WITH EXCAVATION
     
     
     

   The volume difference between the reference terrain and the current state is displayed in the property bar.
   

   Your terrain should then look as follows:
   
   For the internal staircase, an additional excavation must be defined.

10. Display the "GF" storey manually by double-clicking on the storey icon.
11. Start the TERRAIN function and then the EXCAVATION function. Ensure that the type of entry is set to "Drawing the contour".
    
    
12. The drawing functions appear in the Input Assistant. Switch to the drawing function POLYGON.
    
    
13. Draw the polygon along the red contour.
    
    
14. Enter the values into the excavation dialog.
    
    
15. Create the storey "without structure" manually by double-clicking on the storey icon.

    The excavation for the stairs was created.
    
    

16. Now try to create the excavation for the external staircase.
    
    

Tip

The settings for the excavation can be edited if necessary. In the wire model, either select the excavation contour or, in the solid model, a plane of the excavation and click in the property bar on TERRAIN OPTIONS. The excavation screen opens and the values can be edited.

Tip

Before continuing, save the current status of the terrain so that you always have this excavation state available.
If you show the terrain only, in the menu select FILE > SAVE AS and save the terrain (visible selection) under a separate name.
