Drawing Too Big for Scale Autocad

Issue:

When plotting to PDF, printing to a physical printer, or publishing from AutoCAD, object lineweights display thicker, thinner, darker, or lighter than displayed in the drawing.

Causes:

There are several causes for this behavior, including:

• Plot lineweights is enabled.
• Scale lineweights is enabled.
• Lineweights in the drawing are set to a thick width.
• A lineweight override is set for specific objects.
• Drawing is set to plot by color.
• Quality of the PDF being plotted.
• Lineweights or transparency settings in the plot style table (CTB or STB).
• Default setting for lines is not set to 0.

Solution:

Try one or more of the following to resolve the issue:

Lineweight display looks different in AutoCAD from the hard copy or plot

This might be due to lineweight display being deactivated:

1. TypeLWDISPLAY in the AutoCAD command line to toggle the lineweight display.
2. Type ON to switch on the variable.

Turn off lineweight options in plot or page setup

In the Plot or Page Setup dialogue window, turn off the following two settings:

• Plot object lineweights.
• Scale lineweights.

On Windows:

On macOS:

Change lineweight to the desired thickness

1. On the ribbon in AutoCAD, click the Home tab  Layers Panel  Layer Properties.

2. In the Layer Properties Manager, under the Lineweight column, click the lineweight to change.

3. In the Lineweight dialog box, choose the lineweight to use as the default for objects on that layer.

Set the object lineweight to be controlled by the layer

1. Select the objects.
2. Type PROPERTIES on the command line and press Enter.
3. Under the Lineweight drop-down, select ByLayer.

Note: Blocks and Xrefs will need to be opened to change the lineweight for objects within them.

Check that the layer is using the correct lineweight

1. Check the used layer for the component in Property Palette.
2. EnterLAYER.
3. In the Layer manager, go to the relevant layer.
4. Set the desired lineweight there.

Change the lineweight for dimension lines

1. Check which dimstyle is used for the dimension which has thick lines.
2. Enter DIMSTYLE in the AutoCAD command line.
3. Select the corresponding dimstyle.
4. Change the lineweight to a thinner style.
5. Press OK.
6. Some dimensions might need to be created new.

Select a PDF plotter or settings with higher plot quality

Plot using the AutoCAD PDF (High Quality) plotter or adjust the setting of the selected driver for highest quality plot.

Lineweights or transparency in the plot style table

Follow one or more of these procedures:

• Ensure that everyone is using the same version of the CTB file. See: To install plot style files (CTB and STB) into AutoCAD.

Note: It might also be possible to set a common path for the CTB file, for example using a network folder.

• Set the plotted lineweight and transparency in the desired plot style table (CTB). Also see: To Set the Plotted Lineweights.
  1. TypePLOT on the command line.
  2. Press the button next to the Plot Style Table to edit the CTB file. This example edits theGrayscale.ctbfile.
  3. In the Form View Tab, edit the Lineweight for color 1 as desired. For example: set it to 0.7000 mm.
  4. Click Save As to make a new Plot Style Table.
  5. Name the new Plot Style Table file. For example, Grayscale_edited.ctb.
  6. Press Save and Close.
  7. Press ESC to exit the plot layout window.
  8. TypePLOT again and change the Plot Style Table to Grayscale_edited.ctb
  9. Click OK.

Line thickness settings in the PDF viewer

Follow any of these solutions:

• Ensure that everyone is using the same PDF reader software (Adobe Reader, Foxit Reader, Google Chrome, Microsoft Edge, etc.).
• Select a PDF plotter or settings with higher plot quality.
• Try deactivating or activating both these settings, according to the used PDF viewer:
  • Smooth line art.
  • Enhance thin lines.

Check the settings of the Default lineweight value for Polylines.

1. Type LWDEFAULT to command line and Enter.
2. Change the value to 0.​​​​​​​
