BIMINVERTSPACES command

Converts a set of input 3D solid entities and closed polylines, which represent spaces, to a building structure which encompasses these spaces.

Description

This command generates BIM elements in between a set of 3D solid entities and closed polylines. The result represents a building structure made of walls, openings, slabs, and roofs. You can define the options through the command context panel, as well as through the Command line.

Note: This command is envisioned to be most useful in a Scan to BIM workflow. For more information, see the article Point cloud Scan to BIM workflow.

Method

The command takes closed polylines (created manually or using the POINTCLOUDFITPLANAR command) into account and creates parametric opening components based on these polylines. The polylines do not need to be coplanar with a face (exactly on the face) of the space. When polylines are detected on both sides of the wall, the two polylines are interpolated and the opening is created based on the interpolation results. The parametric opening object can then easily be replaced with a window or door component, using the BMREPLACE command.

Launch the command to open the Invert Spaces command context panel.
