In some cases there are some buildings among a group of agents, the agents in the area of build should be removed. But we don't want to use the "inverse placement" (Inverse Placement). The 2 reasons are:
Like the below image, there is a group of agents and we don't want to place them inside the building area no matter where we put the building or place node.
So we can use theĀ Delete Zone.
Place node and building
Create a polygon plane and put the plane the same place of the building among the agents.
This plane can be translated, rotated or scaled, and its components (faces, points) can be edited.
Extracted Zone
Select the plane and click: Miarmy > Placement > Mark Mesh as Delete Zone
Then when you place the agents, the agents inside the marked zone will be automatically removed.
delete zone
Attribute we added onto the shape node of the mesh, turn on/off the feature of delete zone
