Pro-E is one of the best out there but it is far more complex than the average CAD user will ever need. If you are working in the aerospace industry it is almost a requirement if you are making wooden horses to sell on the internet Pro-E is way overkill, like I said each package has it's place. I get into some pretty complex design work ,things like gages for turbine blades and Pro-E is overkill for me, it would do the job but the extra complexity involved would make the job take longer than the CAD program I use now. Pro-E is a history based parametric modeler which requires extra input to allow changes down the road, Keycreator does not require that extra input yet allows almost unlimited changes with a few functions such as box move , offset face and dimension driven editing. In other words I create my model however I want to with no regards to any specific order and if I want to change something later there are a few simple commands that allow me to do that. Parametrics were great when they first came out for making changes, they are an out of date and complex way to do things now compared to some of the new modelers. That is why to chose a CAD program that fits your needs you have to try them for yourself, don't listen to hype don't listen to the guy that says Solidworks is best because everyone uses it you have to decide on your own. I have either used myself or talked to someone that has used almost every CAD program out there, some are great some suck in the end I made my decision based on users I talked to demo's I tried myself and now have been using the same program for almost 10 years it is perfect for my line of work it was easy to learn and it is easy to use plus it does not cost $10,000 like you might pay for a seat of Unigraphics or Catia  |
