Switching to a view in AutoCAD Products causes the expected drawing content to disappear from view. The drawing may then appear empty, or unexpected data may be displayed. This may happen especially when switching to a default view: Top, Back, Front, Bottom, Right, Left, SW Isometric, SE Isometric, NE Isometric, NW Isometric.


The drawing contains very sparse or out-of-scale data.

Note: Selecting one of the default views causes AutoCAD Products to also zoom to the extents of the drawing.


Check for and delete sparse or out-of-scale data by doing any of the following:

  • Press CTRL + A to select all objects and check for far away grips.
  • Enter QSELand cycle through the object types, such as Line, to locate the actual drawing data.
  • Select the valid data and use WBLOCKto export it to a new drawing.


After specifying a custom user coordinate system (UCS) within an active viewport in AutoCAD, when placing an ordinate dimension (DIMORDINATE), its value is wrong, reflecting instead the world UCS.


Use the UCS command in an active viewport to specify an x,y origin point. Once this is done, an ordinate dimension will not reflect this zero point even though other commands will.


Do one of the following:

  • Install the latest update for AutoCAD (see Install Updates, Add-ons, and Enhancements).
  • On the command line in AutoCAD, type DIMASSOC and set the value to 1.
  • Place the UCS in model space from the Model Space tab and then place the ordinate dimension in the viewport.
  • Change the viewport scale to match the model space scale before placing the UCS. The viewport scale can then be changed. 
  • Use a previous version of AutoCAD to place ordinate dimensions.


Express Tool ribbon user interface is missing in AutoCAD Products.

  • The EXPRESSTOOLS command doesn’t activate it but the normal Express Tools commands are working from the command line. 


Missing acetmain.cuix and acetmain.mnl files.


To make the Express Tolls ribbon visible again do these steps:

  1. Copy acetmain.cuix and acetmain.mnl files from a working same version AutoCAD .The standard location for these files is C:\Users\<user>\AppData\Roaming\Autodesk\AutoCAD 20xx\Rxxx\<product language>\Support\ )
  2. Paste the files to the following local folder C:\Users\<user>\AppData\Roaming\Autodesk\AutoCAD 20xx\Rxxx\<product language>\Support\
  3. Load the Express Tools CUI File in AutoCAD
    1. Enter CUILOAD on the command line.
    2. Click “Browse…” and select the acetmain.cuix file from the mentioned preceding location. 
    3. Click Load and then Close.


When plotting a drawing that contains OLE objects from AutoCAD, one or more of them do not print.

This may occur when plotting to a physical printer or to PDF, and they may still be shown in plot preview/layouts. Upon saving, closing, and reopening the DWG file, the OLE object in question may appear to have been removed.


  • Resolution differences between the OLE output versus the printer driver.
  • Low printer driver resolution setting.
  • Page orientation rotated (i.e., portrait/landscape) in AutoCAD but not in the printer driver.
  • Insufficient system resources either on the workstation or the plotter. 
  • The machine only has an integrated graphics card.
  • Objects created by non-Autodesk Products. 
  • Large amount of information copied from another application (Word, Excel, etc.) and pasted into AutoCAD.
  • Outdated plotter driver.
  • PDF viewer cannot display objects. 
  • Antivirus/Firewall blocking the application.


Change the Plot Quality setting of the affected OLE objects

  1. Select the OLE object.
  2. Open the Properties palette.
  3. Change Plot Quality to High Graphics.

Note: Any setting may make a difference but usually High Graphics is best.

Increase the printer resolution

  1. Enter PLOT at the command line to open the Plot dialog box.
  2. Autodesk AutoCAD 2016 Free Download
  3. Select the Printer/Plotter and click the Properties… button next to the name of the plotter.
  4. On the Device and Document Settings tab, choose Custom Properties, and click the Custom Properties… button.
  5. Autodesk AutoCAD 2016 Free Download
  6. Increase the resolution (DPI) where possible (options vary for each device/printer driver; check specific printer documentation for assistance):
    • For AutoCAD PDF drivers, increase DPI for Vector Image Quality and Raster Image Quality.
    • Autodesk AutoCAD 2016 Free Download
    • For physical printers/plotters, adjust Detailed Settings > Print Quality, when available.

Resize the OLE object

Scale the OLE object up or down very slightly. It may be necessary to use MS Paint to edit the image (see video: plot OLE objects).

Lower the page size

Test using a smaller page size so that fewer system resources are utilized.

Create a new image from the original

  1. Use the Windows Snipping Tool or other image capture software to create a new copy of the image. 
  2. Delete the original image from the file. 
  3. Attach the newly snipped image.

Clean Windows and AutoCAD Graphic Cache Temp Folders.

  1. Clean Windows TEMP Folder. See How to delete temporary files in Windows.
  2. Clean AutoCAD Graphics Cache Folder. See How to address display issues by clearing the graphics cache.

Objects were created by non-Autodesk software

  • If objects are contained within a block, EXPLODE the block and try printing.
  • Create an object in the drawing that does print, use MATCHPROP to match the properties the new object.

Ensure the machine has a dedicated graphics card

See: Certified Graphics Hardware.

Update Plotter Driver

Check the website of the plotter manufacturer, to get the recommended driver for the plotter under the current operating system. See: How to acquire the appropriate printer driver for AutoCAD.

Antivirus or Firewall may be blocking the application, add an exception to discard Antivirus as root cause.

See: How to set up antivirus (AV) exclusions to improve stability and performance of Autodesk software.

Additional system troubleshooting

  • Test a different printer.
  • Try viewing the PDF in a different PDF viewer. 
  • Increase plotter memory.
  • Send the plot to a device with more memory.
  • Increase swap file size on the workstation.
  • ​Set the plot device driver to Process in Computer.
  • Try copying a smaller amount of information (spreadsheet cells, text content, etc.) from the source application.

Additional troubleshooting

  • If custom settings have been added to AutoCAD, try How to reset AutoCAD to defaults.
  • If a reset does not help, do a clean-uninstall and reinstall of AutoCAD and test without adding the custom settings back into AutoCAD.
