Types of Measurements

You can measure the following types of entities:
Entities Measurement displayed
point to point Distance between the two points and delta X, Y, and Z
point to edge Projected perpendicular distance and closest distance from the point to the edge
point to face Perpendicular distance from the point to the face
edge to edge Perpendicular or closest distance, delta X, Y, and Z, total length, and angle
edge to face Normal or closest distance and angle (Parallel is defined as the edge being perpendicular to the normal of the face plane.)
face to face Normal or closest distance; angle if not parallel
single edge Length of edge (distance between endpoints)
single hole Diameter, X, Y, Z components of center point, and depth of hole
two holes or circles Distance and delta X, Y, and Z between centers
circles Center point X, Y, Z coordinates and diameter
arcs Center point X, Y, Z coordinates, diameter, arc length, and chord length
a planar face and a cylindrical face Normal distance
two cylindrical faces Center distance, X, Y, Z coordinates, and total length

Circles and arcs must be on a plane.

Holes must be cylindrical and be identified by hole markers, which are inserted by the CAD publishers.
