WebFeb 19, 2024 · Counterbore symbol The symbol used to callout a spotface is the counterbore symbol with the letters SF in the middle. This is per the engineering drawing standard ASME Y14.5. At times, a blueprint may indicate a spotface feature simply through the use of a counterbore symbol. WebStandard Practices- Reading Direction All dimension and note text must be oriented to be read from the bottom of the drawing (relative to the drawing format). Placement of all text to be read from the bottom of the drawing is called unidirectional dimensioning.

WebFeb 26, 2014 · But we have to manually create the counter bore callout in the drawing. This is a dual dim drawing with metric as primary. Shouldn't Creo be able to recognize this as a counter bore in the drawing (or 3D annotation) and show it as something one might use in the industry? It is one feature after all. Thanks. WebJun 22, 2016 · First, let’s work on the four length dimensions at the bottom of the left view in Figure 1. For distances like these, we need to use the location dimension per geometric dimensioning and tolerancing standards to define feature locations rather than feature sizes. Defining the longest distance, 1.940 in, and the shortest one, 0.180 in, is easy. hill country social kerrville
