🔍 Key Concepts

• Mechanical drawing conventions for holes and circular features • Difference between radius and diameter in dimensioning • How leaders and symbols on a drawing point to the curved edge or to a linear distance

💭 Think About

• Look at exactly where the leader line that has 3/4"R on it touches the object—does it touch the flat top surface, the side, or the curved edge of the circle? • Ask yourself whether the 3/4" value is describing a straight-line distance across the circle or from the center of the circle to its edge. • Compare the way the 1/2" dimensions are shown with the way the 3/4"R is shown—are they drawn the same way or differently, and what does that usually mean in drafting?

✅ Before You Answer

• Verify whether the letter "R" is normally used in drafting to label a radius or a diameter. • Confirm if any straight dimension line is drawn across the hole to show a full width; if not, what circular measure could 3/4" be describing? • Make sure you are distinguishing between the cylindrical hole and the rectangular notch on the right side of the block—check which feature the leader with 3/4"R is pointing to.
