how to draw dashed line in autocad: A Step-by-Step Guide for Beginners

Drawing a dashed line in AutoCAD is a common task that helps differentiate elements within a technical drawing. To create a dashed line, you simply need to assign a dashed linetype to your line object. Here’s a step-by-step guide:

1. Open your drawing in AutoCAD and select the "Home" tab.
2. Draw a line using the LINE tool.
3. Open the Properties panel or right-click the line and choose “Properties.”
4. Set Linetype:If "Dashed" is not listed, type LINETYPE in the command line and press Enter.
5. Click “Load,” select “DASHED,” and click OK.
6. Back in Properties, assign “Dashed” to your selected line.
7. If the line still appears solid, adjust the LTSCALE (line type scale). Type LTSCALE in the command line and set to an appropriate value (for example, try values from 0.5 to 5). Zoom in/out as necessary.

Once you’ve assigned the dashed linetype and adjusted the scale, your line will display as dashed, making your drawing clearer and more professional.

Tips 1:

As an interior designer, I often use dashed lines to indicate elements like overhead cabinetry, future walls, or demarcate zones within spaces. For higher accuracy and visual clarity in your plans, combine custom linetypes with detailed 2D floor planning tools—it ensures your dashed lines align perfectly with the overall design intent.

FAQ

Q: Why doesn't my dashed line show up as dashed in AutoCAD?

A: Ensure you’ve set the correct linetype, loaded the “Dashed” pattern, and adjusted the LTSCALE (line type scale) to an appropriate value. Try different scales if needed.

Q: How do I make all dashed lines more visible on my layout?

A: Increase the global LTSCALE variable or adjust the linetype scale in the object’s properties until visibility improves in both model and paper space.

Q: Can dashed lines represent electrical or plumbing routes?

A: Yes, dashed lines are often used for such elements in professional drawings, just be clear with your legend and annotations to avoid confusion.

Q: How can I create custom dashed linetypes in AutoCAD?

A: Use the “Make Linetype” (MKLTYPE) command, or define custom linetype patterns in a .LIN file for advanced requirements.

Q: Do dashed lines print the same as they appear on screen?

A: Dashed lines may look different depending on paper scale and plot settings. It’s always good to preview your print and adjust linetype scale if necessary before finalizing your output.
