Manufacturer element based MEP modeling

[#1]

The solution is to improve Archicad MEP modeling by only allowing modeling with standard-based and manufacturer-specific elements. This solution will provide users with a reliable and consistent set of elements to work with, which will minimize modeling errors and ensure high-quality MEP designs. Standard-based elements ensure that designs are compliant with industry regulations and codes, while manufacturer-specific elements ensure that the specified products are available and appropriate for the specific project.
