How to set CAD annotation leaders
In CAD design, the setting of label leader lines is a common but critical operation, which directly affects the readability and professionalism of drawings. The following are technical discussions and solutions related to CAD marking leads in hot topics on the Internet in the past 10 days for reference.
1. Basic setting steps for CAD labeling leaders
1. Open the CAD software and enter the dimension style manager (command: DIMSTYLE).
2. Select or create a new dimension style and click "Modify".
3. Adjust the leader type, arrow style, and size in the Leaders & Arrows tab.
4. Save the settings and apply them to the current drawing.
| parameters | Default value | Recommended value | Description |
|---|---|---|---|
| Lead type | straight line | spline | Suitable for complex drawings |
| Arrow size | 2.5mm | 3.0mm | Increase visibility |
| Lead color | With layer | red | Highlight important annotations |
2. Frequently asked questions and solutions for users
According to recent forum and Q&A platform data, the following questions are the most popular:
| question | frequency of occurrence | solution |
|---|---|---|
| Leader text is misaligned | 35% | Check the vertical alignment setting in the text style |
| Wrong direction of leader arrow | 28% | Use the LEADER command to redefine the starting point |
| Leader cannot be attached to dimension | 22% | Enable object snapping (F3) |
3. Advanced skills and industry practices
1.Modify leader styles in batches:Use CAD scripts or LISP programs to quickly update all leads in the drawing.
2.3D dimension leader:In the isometric drawing, the Z-axis offset needs to be set to ensure that the leads are visible.
3.International standard differences:ISO and ANSI standards have different requirements for lead angles, which need to be adjusted according to customer needs.
4. Function comparison of popular CAD versions within 10 days
| Software version | New features for leads | User ratings |
|---|---|---|
| AutoCAD 2025 | Intelligent lead automatic avoidance | 4.8/5 |
| ZWCAD 2024 | Batch generation of multi-segment leads | 4.6/5 |
