DescriptionArchitectural design and drafting companies must work systemically using BIM to simplify the complex process of remodeling or refurbishment of an existing structure. You need to create two different models for the existing and proposed structures for this, and then seamlessly integrate them using all the features available. The architectural objects of the existing structure like walls, floors, doors/ windows, etc can be labeled as “existing entities”, while the newly designed architectural objects should be assigned the label of “new build entities”.
