I've been working with motion envelopes a lot over the last several years. This is an incredibly useful tool and my organization creates and uses them frequently. However, they're difficult to create, difficult to use, and difficult to update. It's time PTC gave this tool an overhaul with the end-users in mind.
The list below are my ideas for improvements. I intend to post this to the Creo Community Ideas subforum, but first I'm hoping to hear from the community to discuss what I have so far, maybe crowdsource a few more ideas, and hopefully drum up some votes for the Idea post when that happens. And please feel free to point out spelling/grammar mistakes and ask for clarification on any point.
I'll post this list and any additions to the Ideas subforum in a week or two, depending on how active the discussion here is.
Great to see that you have written an extensive post about improvements of the Motion Envelope. Sorry to see that there is not much response.
Trying not to be all negative but a problem is that there is not much discussions in the Analysis section in total and in the Mechanism Design section it's almost non-existent. On top of that as far as I know PTC hasn't made one single improvement in Mechanism Design for many years. My feeling without knowing is that there hasn't been any improvement in Creo and that the same features are there as they were in Pro/E Wildfire. The only improvements that springs to mind is 3D Contact which might have been during the Creo era.
I really like the MDO module and we have good use of that even though we are missing key features as creating custom formulas for mechanical component e.g friction damper as you can do in Ansys Motion. It's a shame when MathCad is integrated into standard Creo Parametric that you can't use the power of its formula in MDO.
I'm not sure what PTC's strategy is when they are focusing almost all of their simulation improvements on the Ansys simulation integration and what that leaves MDO for the future. Let's hope that it's not completely dead regarding improvements or new features or that they will integrate a new MDO application based on Ansys.
No worries. I figured this subject, and my deep-dive into it, is too obscure for most. A post I made eight years ago about motion envelopes got no response and there just isn't much discussion about them anywhere in the community. So if this post doesn't spur a great discussion, then I hope to at least drum up some votes when we get there.
I think you're right that MDX/MDO is largely unchanged since Wildfire, as far as the function of the tools is concerned. I certainly haven't seen changes to the envelope tool in that time.
3D contact could use some improvements as well. I may have a improvement idea for that in the works...
