For Architectural and Mechanical drawing rules it is already possible to use the DG catalog to assign a rule to the elements it must be applied to. For Structural drawing rules only the Family/Part can be used. Please provide similar functionality...

The IFC schema allows for a lot more quantities on an ifcSpace (Qto_SpaceBaseQuantities): https://standards.buildingsmart.org/IFC/RELEASE/IFC4/ADD2_TC1/HTML/schema/ifcproductextension/qset/qto_spacebasequantities.htm. Please implement those in OBD...

For most building elements the Datagroup System allows for 'Definitions' and Catalog Types/Items on multiple levels: Dataset, Workspace and Workset. Spaces on the contrary don't allow this flexibility. They are set on a "System" level. It is curre...

It would be great if the Curtain Wall tool would also cater for polar coordinate systems, and the geometry issues that come from them. Link to previous discussion

TF_UNIFY_CELL_CHILDREN is a great setting. Apparently can slow things down so something to combine with CVEs? Currently works for these conditions: Wall to Wall. OK Wall to Cell Wall. OK Cell Wall to Cell Wall. OK Cell Wall to Wall-in-Ref. OK Wall...

It would be good to enhance the Add Instance Data tool so that it can tunnel into cells. Link to previous discussion See also ADO PBI 901466: DataGroups: Modify Instance Data Enhancements Another link

It is recognised that components and assemblies need to be replaced intelligently. This is supported at platform level by the Replace Cell tool. Assemblies provide a way to for users to insert a lot of stuff. They will eventually need to manage th...

Want to see the concrete volume for staircase in quantity properties tab.

Many construction projects include work on existing buildings or working in phases, so each phase has items that are existing to remain, to be removed, to be patched, and to be added. While we have a data property for this, it would be more useful...

Enable Program Area of a space to constrain its size (rubber-banding capability) so user can adjust a side and have the shape respond. 2D constraints in MicroStation can do this, see video (the video is real-time; scrub through to get the picture ...
