Compare Files

The compare feature lets you compare two versions of the same 2D or 3D file or two different 2D files. A comparison is useful if you want a clear view of any changes between files or file versions. Supported file formats for comparison include:

2D 3D
RVT RVT
DWG DWG
PDF DXF
IFC
NWD
F3D

To compare files:

  1. Click Files from the left navigation to open the Files tool.

  2. Click one of the files to compare to open it in the viewer.

  3. Click Compare in the top-right to open the compare feature.

    If the file has multiple versions, a different version of the same file will be selected to compare to. If these are the two files you want to compare, click Compare, otherwise continue with the next step.

  4. If no other file is selected to compare to, click Select a document and select the file to compare with.

  5. To change the file altogether, click Change at the top of each file to select a different file.

  6. If necessary, click the Version drop-down list beneath each file to change the version used in the comparison.

  7. Similarly, for PDF files click the Page drop-down list to select which page of a multipage PDF file you wish to compare or for models click the Sheet / View drop-down list to select which sheet or view to compare.

  8. After the correct files are selected, click Compare.

By default, the files are overlaid on top of one another with the differences shown in red and blue. Click to hide the colors.

Tip: Click to turn on or off visibility of each file to help compare.
