If you have used any profiles supplied with Modeler (such as UPDM, SysML, UML, Ada, C++, ACS) in a model, you must upgrade them after installing PTC Modeler 10.3.

If you have added your own objects (including Stereotypes or Tag Definitions) to a supplied profile, they will be deleted when you update the profile. To save these objects, you must move them to a different package before updating the profile.

Open the model then right-click any PTC supplied profile package and select Tools > Update All Profiles from the menu. You can also select the profile, and on the Manage tab, click Update All profiles.

If you are upgrading from 7.0 or earlier, the Upgrade All Profiles... command may not be shown when you right-click the profile. Go to the Access Permissions tab of the profile package and clear the Protected check box, then on the Options tab, select the Profile Package check box and try again.

If you have defined lightweight extensions of supplied profiles, you must set the Profile Package flag on the package which contains them and apply the <<LightWeightProfile>> stereotype to the package. The LightweightProfile Stereotype should only be applied to the outermost Profile Package - not any child packages.

After the profiles are upgraded, close and reopen Modeler before editing the model or opening another model to be upgraded.
