create or change building physical model automatically

edit

Thanks for your answer, but it is not exactly what I'm trying to do. Maybe a simple example can help me specify it a bit more clearly.

Let's say I had already constructed a building model use OpenStudio manual drawing(model 1). I would like to build another brand new model(model 2) which remaining the same floor to ceiling height but enlarge the floor plan twice as it is in model 1. Can this be done without another OpenStudio drawing from scratch?

Here too it depends on how complicated your geometry is to begin with. If you can figure out a way to automatically compute the position of each point that would make up your floor plate, then yes.

So whether there is any tool/software available to automatically compute position points?

@Amy Lee, there may not be a measure that does exactly what you want, but you can adapt some existing code. Here are some example approaches.

1. measure with multiplier for x, y and z axis (quick and easy but maybe not very good approach)
2. measure that makes a copy of your building x feet over from original spaces
3. measure that has x or y value to define a plane, It will then insert specified number of feet into the building at that position. (If that plane crosses a window, the window would also be stretched)

Here is a code snippet for a user script that changes the interior partition height of an existing model. In this use case didn't have to alter x,y,z of zone origin, but if for example we change ceiling height, we would also have to update space zone origins.
