The number and type of information we assign to the objects may vary depending on a project’s stage, the country, industry, etc. Since it is still hard to standardize all this information, the number of attributes assigned to classes in the IFC schema is reduced to the necessary minimum. And that does not mean we can do nothing about it. The IFC schema meets such requirements by Properties, which we can almost freely assign to objects. In this post, I am going to focus on this particular topic.
