Tracing turns visible edges in the camera image into editable feachrs. Give the trace tool a few points on the feature you want, inspect the fitted preview and its score, then choose Create.

This walkthrough traces an aluminum corner, a wood edge, and a hole in aluminum. Each example was created, then deleted before continuing. Refine was not used.

Start from the target icon

1. Open Feachrs → Catalog.
2. Find Corner, Line, or Circle.
3. Click the small target icon in the bottom strip beside the feachr’s name.

The target icon starts tracing. Clicking the main catalog card creates a regular feachr instead. Only feachrs that support tracing show the target icon.

Catalog close-up: Corner, Line, and Circle have target icons in their name strips.

Confirm that Trace Corner, Trace Line, or Trace Circle is open before clicking in the camera view. In tracing mode, those clicks supply trace points. Outside tracing mode, a camera-view click can command machine movement.

Guide the trace with foreground and background points

• Click to add a foreground point on the edge or feature you want.
• Ctrl-click to add a background point on a distracting area you want the trace to ignore.
• Continue adding foreground and background points if the first result is not the feature you intended.

The panel counts both kinds of points. The trace spinner means the tool is working to find a matching feachr. When it finds a sufficiently good match, it displays the preview, parameters, and Trace score.

The spinner beside Trace score shows Corner tracing in progress after two foreground points.

Review the actual overlay as well as the score. A detected shape can have the wrong location, extent, or size for your intended feature. The score is a guide to the fit, not a dimensional accuracy guarantee.

Trace a corner on the aluminum

1. Start Trace Corner using its target icon.
2. Click on one of the two edges forming the corner.
3. Click on the other edge.
