Construction

Building excavation has its own model type EFI (Excavation File). The EFI model can have any name, but we recommend avoiding spaces and other special characters.

Create and Manage EFI Models

You create new EFI models in the model list.

Option to create model in the model list

Each excavation also gets an entry in the command list for the drawing:

EFI model's command in the command list

Standard DDS-CAD functions for move on the context menu are active for building excavations.

Before you can use the move function, you must allow its use. You do this in the building excavation dialog under the options tab. Many useful options then become active on the context menu, for example [Page Up]/[Page Down] to move the entire excavation up/down (all elevations in the excavation are changed by the value you enter). We recommend testing the various options on the context menu for the move function.

Furthermore, you can remove a building excavation from the drawing.

Option to remove EFI model from the drawing

The Remove option opens a dialog where you can choose between Remove and Delete.

Remove means only that you remove the command Excavation(*.efi) from the drawing. With remove, the EFI file remains untouched in the project folder. This means you can insert the excavation into the drawing again later.

If you want to delete the excavation permanently, you must choose Delete.

Work Process for Building Excavation

You can use the following procedure to create a building excavation:

Procedure

  1. Right-click in the model list for building excavation and select Create...
  2. Select calculation type Building excavation
  3. Enter the model name and click OK
  4. Construct the excavation's surface
  5. Define any other layers: Foundations, foundation walls (for backfill against building), mass replacement, ...
  6. Build layers and check the intervention in 3D
  7. Perform mass calculation, check calculations in plan/3D/profiles
  8. Create mass report
  9. Generate cross profiles through the excavation for extra control
  10. Create presentation drawings (separate chapter)
  11. Export layers to surveying instruments/GPS or machine control as needed
