Countersink Callout Drawing

Countersink Callout Drawing - Click hole callout (annotation toolbar), or click insert > annotations > hole callout. Web a countersink consists of a conical hole that is coaxial to a cylindrical hole, where the angle of the cone is determined by the fastener to be used. Is this hole going into a flat surface? Some examples include thread specifications, surface finishes, surface quality, and dimension tolerances. Draw the line radially, so that it points toward the center of the hole, and if extended it would pass through the center point. These callouts help ensure consistency and accuracy during manufacturing and assembly processes. 2 click the hole wizard tool, click the counterbore option, and insert the counterbored hole that goes completely through. Countersink drawings play a crucial role in manufacturing and engineering processes. In the model tree, expand the hole feature, and select the note. I need to call out a countersunk hole in a sheet metal panel.

This handout will focus on the standards of annotation for fasteners, and hole callouts (local notes). Web a countersink consists of a conical hole that is coaxial to a cylindrical hole, where the angle of the cone is determined by the fastener to be used. The measurement units will often be called out in the title block or tolerance block but occasionally will be in another section of the blueprint such as in the notes. Web for countersunk holes, combine the through hole and countersinking callouts into one callout.
