Selecting files to work on
How the file-selection step works at the start of a project — picking which drawings to open and how multi-file selection feeds into the Stage 1 workflow.
Stage 1 — AOIs and Legends
A deeper look at Stage 1 — what auto-detection does for you, what you still have to do, and how to recover when the auto-detection misses.
Stage 2 — Review and amend symbols
What you do in Stage 2 after auto-detection has run — review what's there, add what's missing, fix what's wrong.
Areas of Interest (AOIs)
What an AOI is, how ZeroCount uses them, and how to view, lock, recolour, and delete them from the Zones & AOIs panel.
Manual AOIs
How to draw your own area of interest when the auto-detected one is wrong or missing.
Legends
How ZeroCount uses the legend on a drawing to power Stage 1 detection, and how to set the legend marker manually when auto-detection misses.
Running detection
What happens when you press Submit in Stage 1 — the pipeline behind the scenes, how long it takes, and what to do when it fails.
Confirming markers
How to mark detection results as reviewed, and when confirmation matters in the workflow.
Manual symbol detection
How to use Auto Count Symbol to find more instances of a symbol that auto-detection missed.
Remove Background
Strip background fills, shading, and bleed from a drawing so detection has a cleaner picture to work with.
