Description

Detects floors and ceilings in the visible points of a point cloud representing a building and assigns these points to the detected floors. The detection is based on regions of points with similar Z- coordinates.

Note:
  • For a better floor detection process, hide the points that are not related to the building (environment, other buildings, etc.). You can use point cloud commands like POINTCLOUDCROP, POINTCLOUDREGION, POINTCLOUDCLASSIFY. Turn off the visibility of the non-relevant classes in the Point Cloud Manager panel.
  • The POINTCLOUDDETECTFLOORS command is used as a step in the point cloud Scan to BIM workflow. See the article Point cloud Scan to BIM workflow.

The detected floors are listed in the Point Cloud Manager panel under Buildings.

Note:
  • To edit the selection of points assigned to a floor, right-click the floor listed in the Point Cloud Manager panel and select the Modify option from the context-menu (see the POINTCLOUDMODIFYFLOOR command article).
  • To manually create a floor from scratch, right-click the building listed in the Point Cloud Manager panel and select the Add Floor option from the context-menu. This runs the Add option of the POINTCLOUDMODIFYFLOOR command (see the POINTCLOUDMODIFYFLOOR command article).

Options within the command

Full
Automatically detects floors for the entire point cloud.
Selection
Prompts you to specify the first and second corners of the point cloud area to detect floors in.
Create spatial elements
Choose Yes to let the command create spatial locations based on the detected floors height. You can see the result in the Spatial Locations Manager dialog box and in the Story Bar.
Note:
  • When creating new buildings, the DEFAULTSTORYNAMINGSCHEME system variable defines the naming and numbering of the spatial elements. You can access this info in the Spatial Locations Manager dialog box.
  • When adding new stories to an existing building, the Story Naming Scheme property of the building overrides the value of the DEFAULTSTORYNAMINGSCHEME system variable.
  • With the Story Bar open (STORYBAR system variable is set to 1 or 2), you can easily switch between the defined floors in Top View Mode to start creating walls.
