Beta Testing is in full swing right now. We are getting a lot of great feedback. One thing I like to see is if we can get more people testing Drawings. We did a lot of quality focused work this year. It would be great to get feedback about successes and misses. If you are current on subscription, you can download SOLIDWORKS 2018 Beta 1 directly from your customer portal under Downloads and Updates.
There's also a lot of other great enhancements in most areas of SOLIDWORKS.
If you have comments about specific enhancements you find in SOLIDWORKS 2018 Beta 1, please post on the Beta Forum (and not here) since Beta Releases are under NDA.
