How to draw the border in CAD
In CAD design, the drawing of borders is a basic but critical step. Whether it is drawing specifications or printouts, clear borders are required. The following is a compilation of structured content related to CAD border drawing that has been a hot topic on the Internet in the past 10 days, combined with detailed step-by-step explanations and FAQs to help users quickly master the skills.
1. Basic steps of CAD border drawing
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1. Determine the drawing size | Choose standard sizes such as A0/A1/A2 or customize according to your needs | Need to match the printing device |
| 2. Create layers | Create a new "Border" layer and set the color and line type (such as red dotted line) | It is recommended to manage it in layers with other content |
| 3. Draw a rectangle | Use the RECTANG command to enter diagonal coordinates (such as 0,0 and 420,297) | Ensure closure and no overlap |
| 4. Add title bar | Draw a form in the lower right corner and fill in the project information | Title bar size must comply with industry standards |
2. Answers to popular questions (top 5 searches in the past 10 days)
| question | solution | Related commands |
|---|---|---|
| Border line width is not displayed | Check the layer line width setting or enable the LWDISPLAY variable | LWEIGHT, LWDISPLAY |
| How to add borders in batches | Automate using Sheet Sets or Scripts (SCR) | SHEETSET, SCR |
| Custom non-rectangular border | Offset (OFFSET) after drawing polygons through the PLINE command | PLINE, OFFSET |
3. Advanced skills: Dynamic border template production
1.Property block application: Set the title bar text as attribute (ATTRIBUTE) to facilitate later modification.
2.layout space drawing: Create a viewport (VPORT) in the layout (LAYOUT) to adapt to different proportions.
3.Fields automatically updated: Use the FIELD function to associate dynamic content such as dates, page numbers, etc.
4. Industry standard reference data
| Drawing type | Border distance from margin (mm) | Minimum height of title bar (mm) |
|---|---|---|
| Mechanical Drawing | 10(left)/5(rest) | 30 |
| architectural drawings | 20 (binding edge)/10 | 40 |
5. Common Errors and Troubleshooting Methods
•Mistake 1: Missing borders when printing→ Check whether the printer crop setting or layer is set to "Don't print".
•Mistake 2: The border is misaligned after scaling→ Confirm whether to draw the border in model space (it is recommended to use layout space).
•Mistake 3: Line type appears as solid line→ Adjust the LTSCALE variable scaling factor.
Summary: CAD border drawing requires a combination of standard specifications and flexible operations. Efficiency can be significantly improved through hierarchical management, templates and automation tools. It is recommended to save the tables in this article as a quick reference manual and regularly update the CAD version to be compatible with the latest features.
