Why Inventor?
I'm just wondering why FIRST/Autodesk gives us Inventor instead of AutoCAD. AutoCAD is used MUCH more in the real world. I really can't think of a company that I've been to that uses inventor. The Air Force uses AutoCAD, Boeing Uses CATIA, Delphi uses Unigraphics, AndyMark uses SolidEdge....Other places use Pro-E. What companies DO use Inventor?

Re: Why Inventor?
I know DEKA uses Inventor, also my old company Acu-Gage Systems used Inventor.

Re: Why Inventor?
Autodesk is a major sponsor and Inventor is supposed to be their program for 3-D based modeling and designing.
A lot of other companies use SolidWorks and ProE, but its not like its a bad thing for FIRST. I mean, it is rather good way for modeling. I often do find myself wishing that Inventor used CAD's system of drawing (dimensioning before you draw), but then again, so much of our work we do in robotics is dependant, hence you don't know the dimensions. Inventor is solid, and Inventor Studio is a great way to take modeling and engineering and turn it into marketing and presenting with its rendering capabilities and animating process. It is a branch between CAD and 3dsMAX. That is why. CAD and 3dsMAX are probably Autodesk's two largest programs used in the industry (as of my knowledge, i could be wrong). And by using inventor, you get a taste of the concepts of both. |
Re: Why Inventor?
It would be terrible if we got autoCAD instead of inventor.
Anything that isn't parametric isn't worth using for our applications, imo. |

I do agree with the fact that almost no one in industry has ever heard of Inventor. But, it's our job to show them. When I tell them "it's just like Solidworks" they say "oh, okay, I know what that one is" And here's the thing, FIRST isn't about learning how to do one specific thing or how to use one specific piece of software. FIRST is about learning how to learn. Once you learn on Invnetor, you can make the jump to any CAD system you like. |

On the other hand, engineering companies that design 3D components would be more likely to use a 3D-drafting program such as SolidWorks or Inventor. Sure, AutoCAD can extrude parts and such to create 3D components, but Inventor is better suited to take dozens, hundreds, or even thousands of individual components and combine them into a single assembly. Since robotics generally involves a lot more 3D-modeling than 2D-drafting, we have Inventor. Also, the 10 licenses of Inventor given to each team are the most expensive item in our annual Kit of Parts from FIRST. If any company is donating products worth thousands of dollars to every FRC team, shouldn't we be thankful for said product? ;) |

Re: Why Inventor?
For those schools that offer both a robotics team and the project lead the way curriculum (which I'm guessing is a rather high percentage), Inventor is used in both, and it is helpful in that the students and teachers are fluent in the program come design/build time.

Re: Why Inventor?
If an engineering company that produces or deals with three dimensional objects is using AutoCAD to the exclusion of a 3d parametric software package, like Inventor or Solidworks, it isn't because AutoCAD is better.
It's because the company is made up of people who don't know how and don't want to learn how, to use Inventor or it's contemporaries. AutoCAD has a lot of institutional momentum behind it, but that doesn't mean that it is better. It's just all some companies know. -Andy A. |

BTW CATIA 5 is much different than CATIA 4. I assume you are using 5 since you said there was some carry over. When we switched I forgot all my 4 as quickly as possible. My time with 4 was a very traumatic experience. |
Re: Why Inventor?
Well I am having a strange time switching to pro/E. I keep using the hot keys from inventor.

Re: Why Inventor?
CATIA Likes to change drastically between different versions...heck even between different releases. My CATIA textbook was written for V5 R14. We are using V5 R16 and there are some noticeable differences.

Re: Why Inventor?
I also love Inventor, but would not hesitate to try other CAD softwares. The main reason I use Inventor is because it is provided, and it's a great tool for what we do.

Re: Why Inventor?
Sounds like some of you have experience with many different modeling programs. Besides the details of drawing and assembling, are they all similar in their ability to create iparts?
What about properties such as determine weight, moments, CG's etc? I know I always dream of having the whole robot perfectly designed in Inventor and have it actually tell us the weight to the nearest pound, but there's just not enough time and manpower, and once the real robot starts taking shape, most of the students loose interest in their Inventor model. |
