Attaching underlays created in other file formats

 

When you attach an underlay, a picture representation of the file’s contents is inserted into the drawing. An underlay is similar to an image and different from an external reference in that it cannot be linked and automatically updated.

 

You can attach underlays using files that have the following formats:

 

  • PDF format — Portable document format viewable using Adobe® Acrobat® Reader® and Adobe® Acrobat. The PDF format uses the .pdf file extension.
  • Autodesk® DWF format — Autodesk Design Web Format(used with .dwf files) is used to distribute a drawing for others to view in a Web browser, review, and edit using free Autodesk software and tools. The DWF format uses the .dwf file extension.
  • DGN format — Drawing files used with Bentley Microstation. The DGN for-mat uses the .dgn file extension.
  • PCG format — Point cloud files used by Autodesk® software and tools. The PCG format uses the .pcg file extension.
  • ISD format — Point cloud files used by CADdirect 2022. The ISD format uses the .isd file extension.
