Why rotate
Drawings often arrive sideways — a landscape sheet exported into a portrait PDF, or a CAD plot that defaults to a 90° offset. ZeroCount can detect symbols at any orientation, but the OCR pass that powers Stage 1 (AOIs and legend auto-detection) works best when text is upright.
Rotate before you submit Stage 1 if you can. Rotating afterwards is fine but means re-running detection.
How rotation works
Each rotation step is 90°:
- Rotate Clockwise adds +90°.
- Rotate Counter-Clockwise subtracts 90°.
Rotations are cumulative and wrap around at 360°. The drawing thumbnails update immediately.
Three places to rotate
ZeroCount offers rotation in three different contexts, each scoped differently.
One file — from the file card
- 1
In the Project View, find the file's card in the services panel.
- 2
Click the three-dot menu in the top-right of the card.
- 3
Choose Rotate Clockwise or Rotate Counter-Clockwise .
Use this for one drawing at a time.
Every file in a service — from the service Actions menu
- 1
Click Actions on the service header.
- 2
Choose Rotate Clockwise or Rotate Counter-Clockwise.
Every file inside that service rotates by the same amount. Use this when a whole batch of drawings came in sideways from one CAD export.
One file — from inside the drawing editor
If you've already opened a drawing and notice it's the wrong way up:
- 1
Click Actions in the toolbar at the top of the editor.
- 2
Choose Rotate Clockwise or Rotate Counter-Clockwise.
The drawing re-renders at the new orientation. Markers, AOIs, and zones stay attached to their original positions on the page.
What rotation affects
- Page orientation in the editor and on the file card thumbnail.
- Excel exports generated after rotation — exports include drawing images at the current orientation.
- OCR / auto-detection if you re-run Stage 1 after rotating.
What rotation doesn't affect:
- Existing markers — they stay anchored to the page coordinates they were placed at. So if you rotate after counting, markers still cover the right symbols.
- Existing scales, zones, AOIs, or database links.
Rotation is saved per drawing — closing and reopening the project preserves whatever rotation you set.
