Lock the calculation model

[andrea_pontiggia]

I have to make some small changes to the geometry of the structure, but I would not change the calculation model, how can I do?

I'm afraid I'll need a little more information. Please respond to the following:

I'm assuming you are using Revit Structure and what to edit the model in some what, but you do not want to change the calculation model (I'm assuming you mean analysis model). Since one is inherently attached to the other the analytical model will update with any changes to the model. Please respond to the above and the below.

1. What Product and Version (year) are you working in?

2. What do you mean by small change to the geometry?

3. Is this file on Revit Server?

4. Is this a worksharing file?

Thank you,

Using Revit 2013.
For "small changes" I mean for example when drawing the bracing of "X", they are drawn in the same plane and also the analytical model is drawn on the same floor. In the drawing, however, the bars of the brace will have to be moved in different planes, but in the model will have to stay on the same plane. I hope I have explained.
It is not a file Revit Server.
