When you exchange drawings that contain spaces with boundary offsets calculated by an area calculation standard, the recipient of the drawing must have the same area calculation standard available in their version of AutoCAD Architecture 2024 toolset. If you try to open the drawing in a version of AutoCAD Architecture 2024 toolset where you cannot select that standard in the AEC Options page - meaning that this standard is not installed - all spaces will be drawn with a solution tip icon. To remedy this, copy the DLL for the necessary standard into \\Autodesk AutoCAD Architecture <version>\Space Calculation Standards\ folder. In AutoCAD Architecture 2024 toolset DLLs for these 4 standards are included: Basic, BOMA, SIS, and DIN-277. The Basic standard is located directly in the application folder and should not be moved or deleted.
If you are working with spaces in external references, each space will use the boundary offsets and area calculation standard defined in its containing drawing. This can cause different boundary offsets to be used across a project, so you should verify that each drawing uses the same boundary offsets and area calculation standard.
