Propagate Corner

Command: BimPropagateCorner, Propagate

About 

BimPropagateCorner is one of the five Propagate flavors. It can be used to propagate details connected to three planar base solids (i.e. corners). Common examples are exterior wall-interior wall-slab connections or exterior wall-interior wall-roof connections. For a more in-depth explanation of the general principles of Propagate, read this article on Propagate.

For more information about this command, visit the Command Reference article BimPropagateCorner.

Setting the foundations

In this example the 4 exterior walls, 5 interior walls, and floor slab have already been assigned a composition.

First you must connect the 3 planar types of connections separately. For a detailed explanation of how to do this, read the article PropagatePlanar.

You should now have the following connections: 

Exterior wall - Floor slab	Exterior wall - Interior wall	Interior wall - Floor slab

The nodes where the exterior wall, interior wall, and floor slab come together can't be correctly propagated using PropagatePlanar. Instead, use PropagateCorner. PropagateCorner can propagate details connected to three planar base solids (i.e. corners).

Propagate a corner

1. Launch BimPropagateCorner
   
   You are prompted: Select at least three planar solids that form a 3D corner;

2. Select the exterior wall (1), the interior wall (2), and the floor slab (3).

3. Press Enter to accept.

   
   
   You are prompted: Select detail objects (solids, block refs or faces) to be included in the corner detail (optional).
   If you have extra solids in your detail, i.e. an insulation block, you can select this as an extra detail object and it will be copied to the other nodes when using PropagateCorner.

4. Press Enter when ready.

   Note: if you don't have any extra details, just press Enter to continue.

5. The volume that will be propagated is encased in a purple box.

   You are prompted: Propagate this 3D detail? [Yes/no/Inflate first] <Yes>:

6. Press Enter to accept the detail.

   

   Note: PropagateCorner shows a 3D volume instead of a 2D section.

7. BimPropagateCorner now scans the entire drawing for similar locations. When this is done, the view is zoomed out to show all possible locations. Every suggestion is highlighted and a widget is displayed. A green checkmark means that this suggestion will be applied when pressing Enter.
   

   You are prompted: Choose next action [Apply all/Cancel] <Apply all>:

8. Press Enter to complete the command.
   The nodes where the exterior wall, interior wall, and floor slab come together should now be propagated correctly.
