Pretty self explanatory. Allow the user to convert a construction grid to a primary gird element. Grids are constantly changing throughout the design process due to requirements for columns to shift/etc. The tools for modifying primary grid systems are clunky and difficult to orient for complex geometries while the tools for construction grids are fairly robust.
Alternatively, provide tools similar to construction grids to allow users to add/shift/modify the primary grid system as opposing to relying solely on coordinate input.
I understand there are some limitations in the primary grids to improve. One challenge with converting construction grids to primary grids is that they always have an origin, a rotation and an offset. They also have a default range based on opposite direction grids. Meanwhile, construction grids are just a point-slope. It would be easy enough to convert construction grids to primary (ortho) grids if each one is a unique system with some range based on model limits), but harder to insert them into existing systems. By the way, this tool is useful to add grids based on column (or wall) locations in an existing model. https://bentleysystems.service-now.com/community?id=community_document&sys_id=0f3fb71697718610afb952800153af93
