How to compare Autodesk Drawing eXchange Format Documents Leave feedback

Usually it is very difficult to determine changes that have been made in Autodesk DXF (Drawing eXchange Format) documents. In the same time it is highly popular issue, especially nowadays, when lots of companies have employee who works remotely. Fortunately, with GroupDocs.Comparison API you can easily compare two DXF documents as well as other supported file formats

The result of comparison can be saved as PDF file with highlighting changed, deleted or inserted elements. You can easily change highlighting colors so that changes will be marked differently. Default colors are:

• Objects that were deleted – red
• Objects that were inserted – blue
• Objects that were changed – green

To compare DXF (Autodesk Drawing eXchange Format) documents you should do next:

1. Create new instance of Comparer class passing source document path or stream as an argument
2. Call add method passing target document path or stream as an argument
3. Call compare method to run the comparison process

The following Java code sample demonstrates an approach described above:

The same thing you can do in Kotlin:

Here are examples of source, target and result documents:

Source DXF (Autodesk Drawing eXchange Format) document	Target DXF (Autodesk Drawing eXchange Format) document
