Every year, SOLIDWORKS rolls out a new version of its software and provides Service Pack updates throughout the year for continuous improvement. A lot of these upgrades originate from customer feedback, so be sure to enter Enhancement Requests through the Customer Portal!
Thankfully, SOLIDWORKS lets you maintain multiple versions concurrently under one serial number and on one machine. This can be especially handy for version compatibility when transferring files between companies since SOLIDWORKS files aren’t backwards compatible. Additionally, maintaining the older version can soften the transition of company-wide version upgrades, where older version files need to be retained or where certain feature upgrades aren’t immediately desired.
