How to Change Temporary (System Assigned) PTC Community Username
Newly registered PTC Community members (after August 28th), are system assigned a temporary PTC Community username (aka screen name) which includes a combination of letters and numbers unique to each individual. To optimize the PTC Community member experience, we encourage each member to change the default username to something more creative or personal (i.e. CADMGR, JSmith, Sally_456).
To change your username, follow these steps:
Select “My Settings” from your profile picture in the top menu bar.
