How to open a DWG file

  1. Start with a tool above that lists DWG in its reviewed file-format coverage.
  2. If you only need to inspect the file, filter first for free plans, free viewers, or view-only support.
  3. If you need to change the file and send it back out, favor tools marked Native or Opens + exports.
  4. If support is Partial or Unknown, open the tool review before assuming a clean round-trip.

For broader category context, compare the same format against the rest of the AEC catalog on the landscape map.
