Received dgn files from client & having trouble viewing them? Here’s the list of programs that will help you view dgn drawings or files.
Note: If you want to open dgn file in autocad that’s fine. But I tell you its time consuming! To open dgn file in autocad just use the command “dgnimport“. This is good if you will only open 3-5 dgn drawings. What if you are going to review or plot thousands of these! For sure it will eat too much of your productive time.. 
Here let me share you list of alternative downloadable free dgn viewer to speed up the process.
- Autodesk Design Review + DGN import plugin
- DGN Direct
- Bentley View
- GraphStore
- Columbus
- Autovue
- Safe Software (EME Product)
- OpenEV
That’s all. I’m too lazy to put some description atleast you have a list to start your research as to which DGN file viewer software you will download. Use Google to learn more about this program.
