Dimensioning Rules

When dimensioning a drawing be sure to follow these important rules:

1. Never place a dimension ON TOP of an object.
2. Use SNAP to align dimensions.
3. Smaller dimensions should be placed closer to the object and the overall dimensions should be farthest away.
4. When appropriate use Baseline or Continuous Dimensions
5. Omit redundant dimensions (don't repeat dimensions, this applies to mechanical not architectural dimensions)
6. Use Diameter values to dimension full circles (holes).
7. Use Radius values to dimension arcs.
8. Use Center Marks for circles and arcs.
9. Use center lines for symmetrical objects.
