Part 2: Feature Development — "Dynamic Vinyl Weeding Generator"
Given Flexi 8.1's focus on sign-making, a valuable feature is an automated, intelligent weeding border.
Feature Goal: Automatically create a vinyl-saving border around complex, grouped designs with intelligent gaps. Workflow Integration: Select Artwork: User selects a design.
Define Weeding: Instead of standard "contour," a new button creates a dynamic, rounded, or polygonal boundary that shrinks to fit the design (similar to nesting) rather than a simple rectangle.
Intelligent Splitting: Adds automatic horizontal/vertical lines through intricate areas of the design to prevent the weeded vinyl from becoming one huge, sticky sheet that tears.
Output: Produces a vector outline on a separate, non-printing layer named "WeedLine" to send to the plotter. To make sure I provide the best advice, could you tell me:
