When I tried out Creo for a bit, I was able to find most commands I needed for surfacing within Creo. When I used solidworks for a while it was very different and not as stable in a bad way.
I believe the two aforementioned software do take some inspiration of Creo, however because CATIA and Unigraphics (NX) used to be mainframe type CAD programs.Īs an example I am able to work in CATIA and NX just about the same, each of them have similar ways of producing wireframe and surface geometry. I do know that it's not as easy to use as NX or I will even say CATIA (to me). Creo is not as strong as NX or CATIA in certain ways, but I am not quite knowledgeable in that regard. The Aero side of the aircraft industry does not use Creo as much because it's surfacing isn't as strong, and the software above Creo in the market essentially grew up around Aerospace this means that the expertise of engineers, designers and support personnel in that field is made up of users of the high end software. It is used in the Space Industry frequently because it has good PLM, solid surfacing, and I believe good mechanisms. This is because solidworks does not have the native windchill PLM, and it does not work with surfacing or large models nearly as well. Solidwork's goal was to unseat Creo, which it actually did fantastically, but it has not beaten Creo out of it's last niches.
The other designers can then reference the points without needing to know the details of how a part was modeled. The goal is to manage interfaces from the 'top', allowing designers to say 'this location is important to other groups and may change over time'. In your design of the suspension you could reference both of them. Then have another skeleton that defines how all the suspension components interface to each other, and is referenced from the top level skeleton. For example if you were modeling a car, there could be one skeleton that drives the major overall dimensions such as wheelbase and track width. You can also have multiple skeletons to control different aspects of the design.
This means when you want to change a dimension, you change it in one location and it populates thought the model. The skeleton is then included in all other parts. The basic idea of top town is the dimensions that drive the design are all controlled in one place (in Creo this is called a skeleton).
