What is hole callout?

The Hole Callout tool adds driven diameter dimensions to holes created by the Hole Wizard or circular cut features. Best results are obtained by creating holes using the Hole Wizard. Hole callouts are available in drawings. If you change a hole dimension in the model, the callout updates automatically.

## What does a counterbore look like?

### What does ref on a drawing mean?

REFERENCE
REF on drawings is generally defined as REFERENCE. These dimensions are to be used as reference only.

What is rectangular coordinate dimensioning?

Rectangular coordinated dimensioning is a simplistic method of dimensioning used to locate features. Liner dimensions specify distance in coordinate directions from two or three mutually perpendicular planes. Rectangular coordinate dimensioning must clearly indicate which features of the part establish these planes.

What is the difference between a countersink and a counterbore?

The difference between them is the angle at which the larger hole is drilled. A countersink’s larger hole is tapered at an angle; whereas a counterbore is drilled straight into the material and leaves a flat bottom between the counterbore and the narrower inner shaft.
