TechDraw Roadmap

Here is a rough roadmap of areas to be addressed in the TechDraw Workbench in 2023.

There are 2 main areas of work to address in 2023:

conversion between drawing geometry and model geometry
- these conversions are scattered throughout the code
- the most visible impact is the difficulty in specifying cosmetic geometry
the "lesser topological naming problem"
- primarily making dimensions survive the renaming of reference geometry
  - Phase1 (reference geometry has a new name, but still exists) implemented by PR #8989
  - First attempt at Phase2 (handling situation where reference geometry has legitimately changed) stalled. Rethinking.
- also affects face hatching
- also affects edge appearance attributes

These items would be nice to address in 2023:

drawing overlay
- allow graphics to be added to a drawing page as on a transparent overlay in traditional drafting. This will build on the SymbolsAndTraces research project and @Evgeniy's schematic workbench.
Replacement for Qt XMLPatterns
- the XMLPatterns component will be removed in Qt6. It will need to be replaced by another XML parsing library. This functionality is used in Templates and Symbol views.
  - implemented by PR #9104 (Thanks Werner!)

These items were implemented in 2022:

Navigation modes
New face detection algorithm
PrintAll function
Bitmap hatching fix
Extension line gaps
Section dialog live/deferred update option (implemented as part of complex section)
Convert all templates to "plain svg" (implemented for latin script templates)
View stacking order
Use separate thread for hidden line removal, face finding, section and detail cuts
replace ActiveView Svg creation with simple screen capture
complex section views
easier dimensions from 3d geometry
simple dimension reference repair dialog

These items are still on the infamous TODO list. They will be worked on as and if time allows.
