Techniques
Paused placement — retaining the current scene
Auto-placement switched off for a view: the engine retains the current positions and refuses to re-derive them.

Why use it?
A reviewed layout is a reviewed artefact — pausing freezes what was approved while the model keeps evolving underneath.
When it helps
Baselined publication views, and any diagram whose composition was agreed in a review.
How to read it
- The scene renders retained positions; new elements still need a declared seed position.
- The info diagnostic (auto-placement paused) is the engine stating the contract, not an error.
What you need
- The model
- The retained positions
- Seed positions for anything new
Things to check
- Do not pause early — pausing freezes today's accidents along with today's decisions.
- A new element with no seed position under paused placement is a declaration gap you must fill.
Scope of this diagram
Retention of declared/current positions with auto_place off; it preserves positions, not model semantics.
Work with the converted example
- Open the viewer and select
paused. Inspect the rendered view and its source. - Open the designer. Keep the selected profile and inspect its legal palette and property controls.
- Change one displayed title or an appropriate data value. Apply the edit and check the resulting diagram.
- Run the verifier and review its diagnostics before moving complete content into review.
- Download your edited DDN source to retain the change.
The example uses the indentation-based ddn-next-1 dialect. The language guide explains reusable definitions, dotted data rows and explicit property blocks.
