Running analysis and saving the model with analysis will heavily increase the size of the model (file).

In some instances the user may want to decrease the size of the model.

For that analysis needs to be deleted.

In order to delete analysis, edit a load and just click the OK button.

Then on Analysis tab verify that analysis is not present (see the two screen shots below).

Save the model with a slightly different name and compare the size o the original file with the newly saved one.
