AngryElf,
Just came across this post by looking for other stuff (iLogic examples). Can't make the comparison with Solidworks, since I've only seen it from the outside. But I have to disagree that Inventor would be the superior product. Have been working on it since 2008 now and managed pretty much to bend Inventor's leg into doing what I want it to do. But there are important weak points in the program. One important point is the connection to Autocad. Although I fully understand the link from the marketing point of view, it is also keeping Inventor back from working optimal in its own way. Most visible of course in the drawing environment. An example : if I want 2 parts in an assy drawing having different colors I need to modify the style library, put parts on different layers in the assembly (what if it is a released part ? ) and attach styles to the drawing view. In "friendly" software I select the part in the drawing view assy tree, select the visible line properties and change them on the fly. Other major weak point : robustness of the part tree. It is enough to change the extrusion direction from one-sided to symmetric to make you lose relations in dependent sketches made on the end surface of this extrusion. Try attaching a sketch to a parallel working plane and even projected geometry from XYZ-planes changes into stupid loose lines. Delete a feature and look what IV suggests as "dependent" and you see it is pretty much everything. I could go on for a while...
Yes, Inventor can do a lot but calling it superior is over the top.
For background : I did my first steps in CAD on Autocad (yes ! 🙂 ) on an XT-computer (anybody still knows what that is ? ) and have been on CATIA, SE, NX, PRO-E to name some.

Alex, et al....look, I'm not going to get into a peeing match on this and that here in this thread, there's plenty of those already out there. But honestly, if you haven't worked in SW and Inventor, then no, you can't make the comparison and thus you can agree or disagree all you want, but your opinion isn't based on fact, mine on the other hand is, due to that fact I have hands on experience on both and at the same time. So I'm not comparing today's version of Inventor to 2006's version of SW. As I stated many times, the last version I worked on SW was it's 2010 release, but I do keep current on it here and there as need be. And no offense but the first example you point out I see as you trying to make Inventor act like Acad. It's not Acad any more than SW is Inventor. Inventor doesn't use layers in the same way, while I'll agree that Inventor's drawing environment isn't the best and as far as I'm concerned is lacking some major improvements, it is what it is and there are ways (sometimes numerous ways) to do what you want/need to do. Fact is, not everyone, few actually in my experience print in color, thus not a big need for colors on the detail side of things. If you want to change a part's color on the 3D side, simply select the color override drop down on the quick access tool bar.
As far as losing relationships, etc. I'd have to see how you built the assembly and what parent/child relationships you built in either manually or by default. If you are having issues like such, I's first consider the process you are using before blaming the software. If it's a glitch, it's a glitch, but 9 out of 10 times it's more due to the user's process.
So back to the original claim, yes, Inventor IS in fact superior based on what SW is claiming year after year of "what's new". That is what I'm basing it on. Can Inventor do everything perfectly, of course not and no one is claiming such. Can one package do something better than the other, of course! But when it comes to leading the pack on new tech and new ways of doing something in CAD, Inventor has been the trail blazer since it's 2009 release compared to SW. Case in point and I know this will really get under the skin of SW people here....at what point was SW able to insert or should I say, when were you able to type in a mathematical formula as a parameter while sketching? For example, if I wanted to put in a parameter that was 1/2 the value of another parameter? Or one that was 2x the others value, etc.? Note: SW claimed being able to do such was a "new" feature just in the last couple of releases, so be careful how you answer such. Another note: Inventor's done such since it was born. One last one, again, I don't want to get into a peeing match....At what release has SW been able to import a Catia model and convert it to a native SW file? Or a Pro/E file? An Inventor file? Now, mind you, I'm not talking about bring it in as a neutral file like STEP, etc.
Oh actually, almost forgot about this one. This is a real life issue I had and is what caused us to stop using SW altogether. I worked at a manufacturer that again, used both Inventor and SW (this was the 2009-2010 release time frame). Our parts were typically held to 4 decimal places....very tight tolerances (Stirling engines to be exact). We began to notice that files were randomly out of tolerance, did some research and we were finding the SW files were the ones most commonly the offending files. Of course, the SW people insisted SW is perfect, that it'll butter my toast in the morning if I want it to....So management hired a 3rd party cad house with a Certified Inventor expert and a Certified SW expert to look into matters. They took 10 random neutral (STEP) files and imported them into each program. This was a process we used on a regular basis. They found that the files brought into Inventor were accurate out to the 9th decimal 10 out of 10...the SW files? They were randomly "off" as of the 3rd decimal 6 out of 10 times. This benchmark test was done numerous times on numerous random files just to verify those findings and the avg was 60% of the files brought into SW were off as of that 3rd decimal. Obviously not a risk we could afford to take considering our engines cost millions of dollars a shot.
We contacted SW on this issue, gave them the test results and the files, etc., their reply? "Yeah, we know, but most of our clients don't use it to the tolerance level you guys do, so we don't see it as a big issue right now". My manager flipped (mind you, he was a SW guy) and immediately placed a ban on working on any parts in SW and to begin the move from it. Again, that was it's 2010 release. I can only hope they've addressed it since.
But if you want to go thru SW's latest press release of "what's new", let's start a new thread cuz I've already gone thru it and majority of the "new" features they are touting are things that not only Inventor's been able to do for years, but many other CAD packages as well. But I'm not going to sit here and fill up this thread with a ****-for-tat on a process you or I may not know how to properly use, this isn't the place.
