However, if you install version 7 after version 8, you may need to go back and repair the version 8 installation to fix some minor issues (Windows thumbnails, file associations.) SketchUp 7.1 can be installed along with version 8, and the 2 versions will remain separate.
Only the Pro version of SketchUp 7.1 is available for download, but that's OK - it will revert to the Free version after 8 hours use, and you will be able to continue using it. Currently, the best way to exchange DWG/DXF with SketchUp is to use SketchUp 7.1 & the DWG/DXF import plugin for SketchUp 7.1 (Free)Īlthough SketchUp Free 7.1 also does not have the DWG/DXF import/export capabilities, Google SketchUp did release an optional installer which enables it.Īs of now, both SketchUp version 7.1 and the optional installer are available for download.
As you probably know, SketchUp 8 Free does not include the ability import/export DXF/DWG files.Īlthough there are some free and commercial importers/exporters available, none can match the quality of SketchUp's original plugins.
