File: Save/load subdivision data to/from file
Button „Save“ saves to binary file with
extension .mut. By pressing „Load“ a previously saved binary file can be
loaded. The association between subdivision data and elements is done by the
external element IDs, that means the IDs for elements shouldn’t be modified
after saving subdivision data.
The dialog shows the current project title.
Selecting options „Project title“ or „Another title“ the project title or a
different title is used for saving. Clicking button “Another file title” pops
up a file selection box where a file title is to be selected.
