   * TAD handles early stages of design quite well. You can start on a design, and may not be fully sure of the size and shapes of he rooms you plan to place in your design. Even then, you could possibly get some objective calculations going on in TAD. BIM is not very good at early stages of design   * TAD handles early stages of design quite well.

   * There are architects who think that early stages of design is to do with playing around with //3D forms// ​ This is called //massing// and there are some pre-BIM software that allow this (E.g. Form-it) But massing is NOT the only thing that architects do when beginning a design. TAD uses a type of programming known an //loosely coupled// That means the internal conceptual parts are not attached together rigidly. The architect can himself/​herself decide which is the thing that is important to him/her. If it is massing, well TAD allows that too. But it also allows non-visual ways of looking into the design -- Many times in India, the architect wants to know how much carpet area is getting consumed or what is the FSI (local government body calculations) that is consumed. That is all done quite fast in TAD   * There are architects who think that early stages of design is to do with playing around with //3D forms// ​ This is called //massing// and there are some pre-BIM software that allow this (E.g.

In conventional BIM, as one works on it; it becomes heavier in no-time; and therefore to dismantle and start again design cycles is quite hard+  ​* BIM gets loaded with details as you progress.
