How to Take Advantage of Benefits of Solid Operations in ArchiCAD 8

These tips will help give you some ideas on how to take advantage of the new Solid Element Operations in ArchiCAD 8.

Using Solid Operations for site insertion

1. Go to the story with the foundations of the building (and the mesh representing the site).

2. Select all walls, roof planes (ramps) and slabs that comprise your foundations.

3. Open the Edit.../Solid Element Operations... dialog box.

4. Click on the Get Operators Elements button.

5. Now deselect your foundations and select the site mesh.

6. Click on the Get Target Elements button.

7. Select Subtraction with Upwards Extrusion from the Choose an operation pop-up menu as seen in the screenshot below:

8. Now click Execute and take a look at the mesh in 3D.

The advantage of this method is that the mesh will be fitted automatically to the ramp, even if the building is moved:

Section through the ramp

Using Solid Operations en lieu of the Trim to Roof command

This method has a distinct advantage to the well-known Trim to Roof... command, and that is that even if the roofs are altered after the walls were trimmed to them, the walls will keep up with these changes and will always trim correctly to the roofs. Thus no more re-doing of trimming walls to roofs is needed.

Hint: Solid Operations can also be used as a fast solution for placing walls under stairs.
