In the 2024 Service Pack 3 release, we have enhanced the Planarize command to work better for models with pitched roofs/ floors imported via Structural BIM Import from programs such as Revit©.

The pictures below show an example - on import a horizontal plane would previously be created for every line of horizontal roof/ floor beams, producing an over-complication of the model’s construction levels. The desire was to rationalize the levels and use the planarize command to associate the roof beams with just two inclined planes.

In previous releases, when using the Structure tree context menu “Planarize…” command for a selected inclined plane (IP), this could not be achieved because the beams in question, although detected as lying in the plane, would be labeled as "Defined in plane” (despite each being associated with a separate level), as shown below.

This has now been addressed by enhancing the planarize functionality with the addition of two new categories for the detected beams in the legend band: “Aligned with plane (in other plane)” and “Aligned with plane (not in any plane)”, as shown below. All these beams can then be selected to be moved to the IP, following which operation they all change to “Defined in plane” with their associated plane now being that of the IP. The extra levels generated for each of the beam lines are no longer required and can then be removed using the Rationalize command.

Note also, that when beams are planarized from a level into a sloped plane in this manner, their physical alignment is updated from the level into that of the IP, as shown in the picture below.
