It’s a feature! :->
First, there are three parts to a Plan - a Profile, Bowl Details (segments, thickness, etc.) and Adornments. An adornment is anything you do to adorn a vessel including painting segments or changing defaults in the Storyboard for Feature Ring and Tornado Bowls. When you save a Plan, it saves the Profile, Bowl Details and the Adornments.
At anytime, you can simply open a new Profile and the software will show you what your adornments look like with that new Profile. Instead of opening a new Profile, you can create your own by clicking the Clear button in the Profile which removes the Profile but does NOT delete the Adornments or the Bowl Details.. You can now draw your own Profile and your adornments will be displayed on your new Profile.
The button next to the Clear button is the Clear All button and that eliminates the Profile and the Adornments and resets the Bowl Details to their initial defaults and it is the same as shutting down Segment PRO and starting it again.
Nice feature, huh? Sometimes I have really good ideas. Sometimes they’re not so good. :-0
