Autodesk Fusion recently released an update and you should update the RoboDK plugin for Fusion to the latest version. The latest version should always be available in this link:
//www.sinclairbody.com/downloads/plugins/Fus...plugin.zip

You'll find the steps to manuall install the plugin here:
//www.sinclairbody.com/doc/en/Plugin-Fusion3...ualInstall

We'll update it with RoboDK with the next release (RoboDK v5.4.1) in one week or so.
