Attached to this blog post is a short presentation on the new text and symbol fonts that we are providing in Creo 4.0. Although I'm listing this enhancement under the 2D Detailing area, it is also available in MBD. Any questions or feedback you have related to the new text and symbol fonts should be provided as comments to the blog post. That will be the easiest way for me to keep track of the comments and also be able to provide timely responses to your questions. If you follow this post, you can be notified of those comments as well and be able to learn from what others are asking. I may also periodically update this post to add some new details or information related to this enhancement.   Also, don't forget to follow the main blog post for 2D Detailing - which will have links to other 2D Detailing-related content 2D Detailing Home: Start Here! or the main blog post for MBD Creo 4.0 MBD Home: Start Here!

In Creo 4.0 it is now possible to append wires and cables to branch bundles after the bundle has been created.  If you set configuration option prompt_extract_from_branches then you can control how wires and cables are extracted from a branch   Watch the attached video to learn more

Prior to Creo 4.0. when a cable or wire failed due to violation of a fixed length there were not any tools to remove the fixed length of the failed feature.   With Creo 4.0 from Model Tree, or notification center you can now Right Click and choose Remove Fixed Length.  If the wire has already failed then the fixed length is automatically  removed,  and wire is regenerated - See the attached Video
