General Sketch vs Skeleton (AAX)

Just wondering what the heck is the difference between Sketch and Skeleton features?

For example, when I do Copy Geometry, I know I can copy Sketch elements from a regular Prt file, so I'm wondering why I should buy AAX and get the Skeleton feature.

my 2 cents:

 

First of all, I don't think you can do Copy Geom without AAX.

So then, the question is - what's the advantage of using the skeleton model type?

Personally, I don't think there is much difference from regular model type, but I like to use skeleton .prt model for layouts because the icon is different, and the model type is different.  So it is pretty obvious that this is the "layout model".

And the software gives you the options of hiding the skeleton from the drawing views / removing them from the BOM tables, / excluding it from assembly mass calculations etc...

AAX module is much more than skeleton functionality. If you would benefit from top-down Design tools (almost every use can benefit) then get AAX. Create part from body, external copy geometry, merge/cut out etc. are all part of AAX.

 

I would suggest running through a training module for top-down design before making a decision on AAX if you can. I use AAX every day and get a huge return on the cost to buy it.

First, thank you so much for your reply.

I understand that AAX does more than just skeletons.

What I'm really curious about is how the skeleton method inside the AAX module differs from and benefits from sketching and creating reference elements in a regular PRT file.

Is it just that I can give the skeleton structure a mechanism???

Depending on what design intent you are passing among models there may be little/no difference between referencing an .prt and .skel models.

 

Skeleton models are "part" models that have some properties different from a standard part model. They were introduced to support top-down design in Pro/E when those tools were introduced and were expanded to mechanism skeletons later. They are intended to manage design intent (parent/child dependencies) among multiple models. One criterion for selecting a skeleton would be does the skeleton provide design intent to 2 or more models, if so then it would likely be preferrable to a .prt to capture the intent.

 

Creo has a myriad of functions to capture design intent and without understanding a specific application it is difficult to explain why one would choose a specific function over another. You would need to provide details about how you are creating reference elements in a regular PRT file and the design intent behind why you are doing this to.
