Linear Dimension

Status: Implemented

Linear Dimension dialog

Linear dimensions measure distance between two resolved references in PMI mode.

Inputs

  • id – optional annotation identifier.
  • targets – one or two references (VERTEX/EDGE), resolved as vertex-vertex, vertex-edge, edge-edge, or single-edge endpoint span.
  • planeRefName – optional projection plane/face reference.
  • alignment – view, XY, YZ, or ZX.
  • offset – offset distance for the dimension line.
  • showExt – toggles extension lines.
  • isReference – formats value as reference dimension.
  • decimals – display precision (defaults from PMI mode when available).

Behaviour

  • Recomputes measured distance from live geometry each render.
  • Draws extension/arrow geometry in overlay space and scales visual size with screen distance.
  • Supports label dragging; drag updates stored label world position and offset for stable layouts across reloads.
