I'm looking for more pros and cons on this issue. We have discovered an issue with Multilevel cables.
On Multilevel cables, Creo Parametric "does not" read the cable diameter and minimum bend radius ! It is a known issue that the thickness and min_bend_radius is not brought over. The recommendations is to use assign_min_bend and assign_thickness on the <name>- item in the model tree.
I find this sad that this hasn't been fixed yet. 
It's also interesting that Multi level cables are now overbraids and they don't autoroute. I'm sure there are some reason behind this, that I won't go into. There are some tweaks you have to do in order to manually route the overall diameter, but the diameter is not correct and you have to mess with parameters listed above, basically making the darn thing "non parametric".
This has a big impact on our shielded cable shapes with pairs. Because of this, we are leaning towards creating all of our cable shapes as single level
and removing the pairs and just the cable cosmetics to show the pairs. What are the draw backs doing it this way? One thing I see as you move pins around the cable cosmetics will get messy.
Please chime in if you have some comments on this.
Thanks
