I usually see spur gear ratios stated as best for a range between 1:1 and 6:1 (with efficiencies of 98-99%). What happens as you go to higher numerical ratiosn, e.g. 9:1, do efficiencies go down (a little, a lot, enough to make the increased complexity of a 2-stage reduction a better choice)...
The same basic question on the Alibre forum has elicited some pretty good responses, but frankly, I am not so sure I understand all of what's been written. Here's a link if any of you care to try and help me understand better.
Specifically, why a surface modeler may cause other problems for...

Why do you say this? Due to my inexperience, I don't have a clue of what process or steps in creation will be more diffcult with one tool versus another, which is the orignal intent of the query. Can you share...
I forgot to ask, but another consideration is how do I interoperate with suppliers if I elect to use AD instead of SW?
For example, for parts I expect to be CNCed, will I give them a .STP or IGES file (and which is better for the purpose?). I presume they will be able to open it with SW, but...
A major question is how do I interoperate with suppliers if I elect to use AD instead of SW? For example, for parts I expect to be CNCed, will I give them a .STP or IGES file (which is better for the purpose?) and will they be able to open it with SW, and more importantly, if necessary, edit...
When you speak of surfacing, I presume you mean for molds? Click this link and scroll about half-way down to see an example of the kinds of parts, which we injection mold.

As for swoopy consumer products, here is a link to an example...
I'm not looking to start trouble, nor stir up fanboys. Simply put, I've been using pencil and paper for sketching things and then making prototypes with a lathe and mill. When it works, I have parts made in production quantites with CNC machines. While I have resorted to AutoCAD when...
