CT CADD.08.03: Demonstrate the use of leaders and notes.
CT CADD.06.01: Use modify commands (Trim).
Students execute Plate 1-3. This plate requires complex intersecting circles that must be "cleaned" using TRIM. They will then use the TEXT and LEADER tools to label specific material callouts.
Purpose: To produce clean, "readable" technical drawings.
DOK Level: 3.
Provide a "Leader Style" preset so students can focus on placement rather than formatting.
Accuracy of the "Trim" points (no "orphaned" lines left behind).
