• All programs can now be network licensed on a Windows terminal server.  Contact us for details.

• Dynacam now includes a feature that allows a measured or empirical cam profile to be imported.  The data is then splined and the cam functions created to analyze its dynamics or redesign it with better functions.

• Dynacam Plus allows the design of a cam-driven fourbar or sixbar linkage or slider follower train and can share data with programs Fourbar and Sixbar so that the cam-driven linkage designed in Dynacam can be dynamically analyzed in either Fourbar or Sixbar.

• Programs Fourbar and Sixbar Professional can now share data between them to allow serial connection of multiple linkages of up to N-bars.

• Program Matrix is free with the purchase of any other software program from this site.
