When you select any sketch, face or body the measurement information will appear on the bottom of the screen.
It will show measurement information based on your selection. Eg. if you select a cylindrical face, it will display it's radius, if you select two parallel faces, it will display the distance between them, etc.
The selection info can contain the following measurements based on the type of items you selected:
Quantitative info
The length of a line. If you select more than one line, it shows their sum.
The area of a face. If you select more than one face, it shows their sum.
The volume of a body. If you select more than one body, it shows their sum.
Radial info
The radius of an arc, circle, sphere, cone or cylinder.
The diameter of an arc, circle, sphere, cone or cylinder.
Angle info
The angle between any two lines (doesn't have to be on the same plane) or two faces. In case of arcs, it shows the central angle.
A perpendicular angle between two lines or two faces.
Distance metrics
Distance metrics are calculated by the type of distance (min., max., cntr., prl.) and the actual distance by each axis.
The minimum distance between two lines, two arcs, two circles, two nonparallel faces, two bodies or any 2 item combination of the following: circle, arc, line, face, body.
The maximum distance between a line and an arc/circle.
The central distance between a center point or central axis and any of the following items: line, arc, circle parallel face or body. Centerpoints are calculated in the case of circles, cone, and spheres. In case of bodies, we calculate the distance from the center of gravity.
The distance between two parallel items. The distance between parallel sketches, edges, and faces ( an edge - face combination is also possible). It also shows the radial difference of concentric arcs, circles, spheres, and cylinders.
The distance on the X-axis between two lines, two arcs, two circles, two nonparallel faces, two bodies or any 2 item combination of the following: circle, arc, line, face, body.
The distance on the Y-axis between two lines, two arcs, two circles, two nonparallel faces, two bodies or any 2 item combination of the following: circle, arc, line, face, body.
The distance on the Z-axis between two lines, two arcs, two circles, two nonparallel faces, two bodies or any 2 item combination of the following: circle, arc, line, face, body.
