Angle Dimension

Status: Implemented

Angle Dimension dialog

Angle dimensions measure the sweep between two faces or edges and display the result on the active PMI sheet. Use them for chamfers, draft checks, and assembly alignment callouts.

Inputs

  • annotationID – optional identifier retained in PMI exports.
  • decimals – decimal precision; defaults to the PMI angleDecimals preference.
  • elementARefName / elementBRefName – face or edge selections that define the angle.
  • planeRefName – optional face or datum to override the projection plane.
  • reverseElementOrder – flips the measured side when the automatic choice is not desired.
  • angleType – choose acute, obtuse, or reflex sweep to control value formatting.
  • isReference – encloses the output in parentheses and signals downstream reference handling.

Behaviour

  • Derives edge or face directions, constructs a local 2D basis, and draws an arc with adjustable radius.
  • Arrowheads, witness lines, and arc radius scale in screen space to remain readable while zooming.
  • Labels can be dragged; the world-space location is persisted and reused on reload.
  • Responds to PMI formatting callbacks so custom units or tolerancing schemes propagate to the label text.

Usage Tips

  • Provide a projection plane when measuring between non-parallel faces to control which cross-section drives the angle.
  • Toggle reverseElementOrder if the drawn arc lands on the wrong side of the intersection.
  • Use the reflex option to call out angles greater than 180° without recomputing geometry.
