Another potential issue could be with the plot style settings. Plot styles control how the properties of the objects in your drawing are translated in the plotted output. If your plot style is set to disregard lineweights, they will not appear in the print.

Lastly, the issue could be with the printer settings or the printer itself. Some printers might not be able to accurately reproduce very thin or very thick lines. In this case, you might need to adjust your lineweights or try printing from a different printer.

8. What is the default line thickness in AutoCAD?

The default line thickness in AutoCAD, also known as the default lineweight, is typically set to 0. This means that the thickness of the lines is controlled by the plot style settings when the drawing is plotted.

However, the default lineweight can be changed from the ‘Lineweight Settings’ dialog box. This box can be accessed by typing ‘lweight’ into the command line and pressing Enter.

Remember, the lineweight in AutoCAD is usually represented in millimeters, but this can be adjusted to your preferred unit of measurement.

9. Can change the thickness of a line from?

You can change the thickness of a line from the Properties panel in AutoCAD. After selecting the lines you want to change, open the Properties panel by typing ‘properties’ into the command line and pressing Enter, or by pressing Ctrl + 1.

In the Properties panel, look for the ‘Lineweight’ option under the ‘Misc’ category. Click on the value next to ‘Lineweight’, and a dropdown menu with different lineweights will appear. Select the desired lineweight, then close the Properties panel. Your selected lines will now show the new line thickness.

It’s important to remember that line thickness, or lineweight, in AutoCAD does not affect the actual dimensions of your objects. It’s a visual attribute used to distinguish different elements of your drawing and to improve its legibility when it’s printed or plotted.

10. How do I show line properties in AutoCAD?

The Properties panel is a powerful tool that allows you to view and modify the properties of your objects. It’s a great way to ensure that your drawing is consistent and follows the desired specifications.

11. How do I enable linetypes in AutoCAD?

To use different linetypes in AutoCAD, you first need to load them into your drawing. This can be done from the Linetype Manager, which can be opened by typing ‘linetype’ into the command line and pressing Enter.

In the Linetype Manager, you can load new linetypes by clicking on ‘Load’. You can then select the linetypes you want from the list that appears. Once the linetypes are loaded, you can apply them to your lines from the Properties panel.

Keep in mind that the display of linetypes can be affected by your LTSCALE and PSLTSCALE settings. Make sure to adjust these settings as necessary to properly display your linetypes.

12. Why is my Linetype not showing in paper space?

If your linetype is not showing in paper space, the issue could be with your LTSCALE (Line Type Scale) or PSLTSCALE (Paper Space Line Type Scale) settings. These settings control the scale at which linetypes are displayed, and if they’re too large or too small, the linetype may not appear as expected in paper space.

Another possible reason is that the viewport in paper space is not set to the correct scale. This can cause the linetypes to appear differently than they do in model space. To fix this, make sure to set your viewport scale properly.

Finally, the issue could be with the specific linetype itself. If the linetype hasn’t been loaded into your drawing, or if it’s not assigned to the lines in question, it won’t be displayed. You can load linetypes from the Linetype Manager and assign them to lines from the Properties panel.

13. How do you change the thickness of a line in paper space?

The process of changing the thickness of a line in paper space is the same as in model space. You need to adjust the lineweight of the line from the Properties panel.
