AutoCAD 2018.1.1 Update

AutoCAD 2018 has got another update with bug fixes. This time the AutoCAD 2018.1.1 Update.

Either get it via the Autodesk Desktop App or Autodesk Account. Not publically available on Autodesk Knowledge Network.

Here are some details from the readme:

The AutoCAD 2018.1.1 Update contains all of the updates previously released for AutoCAD 2018 so the download is up to 452 MB depending on if it’s for AutoCAD LT, 32-bit or 64-bit.

AutoCAD Updates can be applied to AutoCAD installed as a standalone application and AutoCAD-based vertical products. You can install the AutoCAD update in addition to any applicable updates for your vertical products listed below.

AutoCAD and Vertical Products:

  • AutoCAD 2018
  • AutoCAD Architecture 2018
  • AutoCAD Civil 3D 2018
  • AutoCAD Electrical 2018
  • AutoCAD Map 3D 2018
  • AutoCAD Mechanical 2018
  • AutoCAD MEP 2018
  • AutoCAD Plant 3D 2018
  • Advance Steel 2018

After applying this patch, the Product Version in the About box will be listed as O.154.0.0 AutoCAD 2018.1.1 Update. If you use one of the vertical products, the Built On version will be listed as O.154.0.0 AutoCAD 2018.1.1 Update. _VERNUM returns "O.154.0.0 (UNICODE)" (read only). When installed it shows up as version in the list of installed updates in Windows.

As a result of the detailed information that we received from customers who used the Customer Error Reporting Utility, we were able to identify and fix several defects with the following results:

  • Occasional crashes when opening the block editor no longer occur.
  • Occasional crashes when selecting or creating a non-associative hatch no longer occur.
  • Occasional crashes when clicking the Insert View button on the ribbon in some drawings no longer occur.
  • Occasional crashes when modifying certain dimension styles no longer occur.
  • Occasional crashes when editing the grip of a spotlight in some drawings no longer occur.
  • Occasional crashes when opening DXF files containing Xrefs no longer occur.

Several additional defects have been fixed with the following results:


  • The attribute position of a block remains the same after editing the block.


  • PDF files plotted from certain drawings now display correctly in Adobe Reader.
  • Hatch patterns in PDF files are consistent with lineweight.
  • Raster images are plotted correctly when Shadeplot is set to the Rendered option.


  • The AEC property-set data in DWG files can be successfully exported to 3D DWF files.
  • Certain Pro/E files can now be successfully imported into AutoCAD.
