How do I call counterbore?
Counterbore symbol If you want to type the ⌴ symbol, hold the ALT key and press 9012.
How do you show counterbore dimensions?
Dimensioning Counterbore Hole Select Dimension Tool in the Annotate Tab > Double Click on the outer circle o the counterbore (NOTE Leader Arrows should always point to the larger hole) This will place the diameter of the large hole Page 9 4.
How do you identify reference dimensions?
The method for identifying a reference dimension (or reference data) on drawings is to enclose the dimension (or data) within parentheses.
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?
A counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature.
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.
What is the symbol for counterbore?
⌴

When is a counterbore considered a datum feature?
When the counterbored hole is a member of a pattern, each hole in the pattern is individually considered a datum feature with the specified datum feature label and the positional tolerance specified for the counterbore is intended to be relative to its corresponding hole.
