The core concept behind Tech Pack Wizard is linked sketches.
Instead of duplicating artwork and manually keeping it in sync, TPW uses two sketch types that stay connected:
- Primary Sketches (PS)
- Detail Sketches (DS)
These work together to reduce errors and save time when designs change.
Primary Sketches (PS)
Primary Sketches are where you create and update your flat sketches.
- Each Primary Sketch lives on its own artboard
- Each artboard should contain one view only
(front, back, side, etc.) - Primary Sketches are fully editable
Think of Primary Sketches as your source of truth.
Detail Sketches (DS)
Detail Sketches are linked copies of a Primary Sketch.
- Each DS is connected to a specific PS
- Detail Sketches are not directly editable
- This is where you add:
- Spec POMs
- Callout lines and text
Because they are linked, Detail Sketches always reflect the latest design when your file is saved.
What happens when the design changes?
When you update a Primary Sketch:
- All linked Detail Sketches update automatically after the Illustrator file is saved
- You don’t need to redraw, re-copy, or manually sync changes
- Your annotations stay aligned with the latest design
This eliminates one of the most common causes of tech pack errors: out-of-date sketches.
