CAD Section cut dialog should have a default preview turned off. Or add option to AutoPreview

The CAD Section cut dialog always starts sectioning before a user has any opportunity to defined method, location, size of section, etc.  Depending on the CAD model complexity, the current units and PC,  it can mean a very long wait on the dialog.  Also, as user makes changes, every change refreshes.  I suggest a checkbox that defaults to Off for preview of resulting section.  Kind of like on our Designer software. You can choose to have preview always active or not.
