I am using idecad architecture 7. I need to take a quantity, I also watched the training videos, but I could not solve the issues I will talk about 1- How do I define and throw the objects that I want to appear in the quantity, such as alum ceramic parquet as a layer 2- How do I define two different objects in a defined area. (I want to use ceramics in the entrance hall, but the remaining area It will be parquet ) 3- I saw in some videos that there are very different materials in the building components, I only have examples, where can I get them? 4-Is it possible to make a suspended ceiling, if it can be done, thanks in advance, good work
