Basic Types of Dimensions
Dimensions in AutoCAD can be categorized primarily into two types:
- Size Dimensions: These indicate the measurement of an object feature.
- Location Dimensions: These clarify the position of an object relative to another.
Common Chamfer Angle
A typical chamfer is often created at a 45° angle, acting as a transition between two surfaces making it a fundamental element in design.

Questions Frequently Asked
1. Why can’t I see my dimensions in AutoCAD?
- Ensure that your layer controls are appropriately set, and no dimensions are hidden. If you see dimension lines without text, it might indicate that the text size is too small relative to the drawing scale.
2. How do I fix dimensions that appear incorrectly?
- Go to the Dimension Style Manager, select the affected style, adjust the scale in the Fit tab, and apply changes to rectify dimension appearance.
3. What can I do if my drawing appears too small in AutoCAD?
- Reset drawing limits by entering the command LIMITS, adjust your zoom settings with commands like Z + Enter followed by A + Enter, to ensure everything is viewable.
