Triming a projects square footage. Is there a method

[philipnoland]

Right now my goal is to reduce the square feet of a house. The house is very symmetrical and the subtraction of space is relative to these symmetry lines. For example I have established 1foot sections that run through multiple rooms. Particularly through room openings, of which I want to reduce. Ultimately to bring the square footage down.

My first inclination is that Revit has so many alignments and locked parameters that this procedure is nothing more that moving each wall at a time. However there is a glimmer of hope that I may be able to split multiple walls at once and then re-align pulling all elements of the house over.


Is this possible?

Hard to say without actually seeing it, but, whenever I am faced with this dilemma, I'll make a backup copy and operate on it. To answer your question, if you have only completed the floor plan, great, if not, no real biggy either.

It is OK to split and move/rejoin. That is really easy. So is picking a full set of elements on one side of the house, and just moving them all one foot in a given direction. If your model scrambles, try it using a disjoined move. If you end up with spaghetti after that, then try your split and rejoin. In fact, any one of these three ways of doing it will work depending on how your relationships are set up, or not. Remember, undo is your friend today.

If your slab/foundation is done, and your relationships are correct, this can be a piece of cake, and Revit should update those elements automatically. Same with your roof.
Just be sure to underlay your first floor when in foundation view to insure your slab and walls line up 100%. Same with your roof.

This gets to be a real simple and confident operation after you have done it a few times. Just take nothing for granted in terms of what Revit will update, or not, and visually cross check everything once you finish resizing your project. Don't immediately press cancel if you get a walls overlap, or similar warning, use that to your advantage, and prompt Revit to show you those conflicts, and they are usually an easy fix. Same goes for dimensioned elements that already exist, Revit will warn you a dimension is about to be deleted, and that's OK. There will almost always be some clean-up, depending on how far along the model is progressed.

Thanks for the talk.
I spent most of the day doing many of those things. I am new to Revit but am very familiar with just going for it. I found that the selection process is tricky. However the best technique is backing up the file.

I found that a lot of my trim boards and modeled families get in the way the most. I suppose there is not a quick way to regroup each member, only to create them in different families from the get go.

Thats the scoop for today. I figured there was many methods out there and the best way to find them best one is running into them while you try different things, and just seeing what works best.

Aligning and locking to the grid system is also handy. I think next time I will start locking items more so I don't get so much spaghetti.

thanks billygrey
