Working with Traces

Working with Traces

Most trace editing is on the field context menu (right-click selected traces), with keyboard shortcuts for the common actions. Selected-trace actions affect all selected traces.

• Edit attributes (Ctrl+E) — change name, color, tags, and fill mode.
• Merge traces (Ctrl+M) — merge the exteriors of selected traces (they must share a name).
• Hide (Ctrl+H) / Unhide all (Ctrl+U) — hidden traces can't be edited until unhidden.
• Make negative / positive — negative traces subtract from (cut into) the area of same-named traces, e.g. to carve a hole; this matters for area and 3D volume.
• Cut / Copy / Paste (Ctrl+X / Ctrl+C / Ctrl+V) and Paste attributes (Ctrl+B) — copy a trace's name/color/tags onto selected traces.
• Delete (Delete or Backspace) — delete the selected traces.

On the field (right-click empty space, or use the shortcuts):

• Select all (Ctrl+A) / Deselect (Ctrl+D).
• Toggle hide all (H) and Toggle show all (A) — temporarily hide or show every trace regardless of individual hidden state (the field border turns red when all are force-hidden, green when all are force-shown). These differ from per-trace Hide/Unhide.
• Blend (Space) — blend the current and last-viewed section, to compare them.
• Toggle hide images (I), Focus mode (X).

Undo (Ctrl+Z) / Redo (Ctrl+Y) cover actions on the field. (Some edits made through the lists are noted there as not undoable.)

Find a contour on the current section with Section ▸ Find contour… (Shift+F); jump to an object's first contour anywhere in the series with Series ▸ Find first object contour… (Ctrl+F).
