Autodesk Inventor vs. AVEVA Everything 3D (E3D) vs. CATIA

Autodesk Inventor is a great tool for students and faculty for engineering areas that don't require great precision or development of more thorough scientific results. Is you are conducting research, or deal with very intricate and complex systems I would recommend a more robust platform that complies more to industry standards.

When it comes to modelling a product using multiple parts, CATIA becomes tedious. One need someone to sit with and learn with the experience from a frequent user. If switching from any other software to CATIA, it can be intimidating as learning curve is lengthy. For example, when working with complex shape in a knuckle joint, more steps are needed in part modelling. This cause part modelling lengthier and consume time more time, in comparison to SOLIDWORKS. However, CATIA is tremendously helpful in generating really complex features. Surface modelling is way easier when one know how to use it. It becomes really handy to make changes to the design later as well. The design history tree is also very well organized, which save time in later modifications

• The program is very good at simplicity. Each of the buttons, menus, and options has an explanation of exactly what the feature does, and even a more advanced description if you desire to learn more about what each one does.
• Autodesk Inventor is a very fast program. Everything renders extremely quickly and there are no delays when examining a 3D model, part, or assembly. This is especially useful when giving a presentation about a product or design, and you need to be able to show a concept to an audience in real time.
• The software has an extremely accurate simulation feature that lets users do stress analysis on a 3D model. It can calculate precisely where the stress concentrations are going to be in a particular model and even give you an accurate depiction of where the part could likely fracture and/or fracture during loading.

• Surface modeling module is extremely developed and successful.
• 2D drafting module is doing the job effectively (AutoCAD is no more required).

• most if it still runs on a single core. Please fix this
• Crashes. In our experience, too many crashes. We have high end machines and crashes are way too common.
• Autosave. I think it is simply unacceptable that Autodesk Inventor combines common crashes with no autosave functionality. We feel this pain all the time.

• The software is pretty heavy, even with computers designed for heavy-duty loads, resulting in long wait times to load files and make changes, reducing productivity.

Inventor continues to meet our enterprise needs. I don't see a need to change unless we change our business model significantly.

It is quite user-friendly as long as you have the computing power to download and use it. However, this makes it quite inconvenient if you are trying to access files on different devices, as Inventor has to be loaded on all of those devices. While the program itself works just fine, it would be much better for my application if it, or a version, were web-based and allowed users to access and modify projects from anywhere.

It is a good software for conception. But it is too hard sometimes to work with and understand the different options available

I think the support for Autodesk Inventor is very good. The staff at our reseller were very knowledgable and able to walk us through problems pretty easily. The training we received was very good also. I will say that there were a couple of times we reached out to support with a question or challenge we had, and the support agent was not able to resolve our problem, and after touching base back we found out that there was not a solution for the problems we were experiencing. One of them was just how Inventor represents colors inconsistently at times, all things being equal. Another was that Inventor would not let decals on parts transcend to the assembly level. they just would not show up.

We got frequent updates on CATIA. There are lots of update notes. Also, there are lots of lots of videos online to solve the issues that you can stumble upon. It also has a built-in help manual, which helps occasionally. I have gotten my education through a physical class on CATIA, so there are opportunities like that as well.

I got the training during college, so mostly i learned on my own

When it comes to solid modeling, the bad choices died out years ago. So we looked at the total ecosystem and chose Autodesk Inventor because of the integration with Nastran, HSM (machining), Autodesk CFD, MoldFlow, and AutoCAD. This means our legacy data (2D) is still a valid part of our design methodologies going forward, and we have the full breadth of engineering tools at our disposal. Other solutions in this space have similar offerings but not nearly as potent of a portfolio in total. It's worth saying that we do not consider Inventor in the same space as CATIA or NX, but that the entire Autodesk portfolio (e.g. Alias, PowerMill, etc) includes a total toolset that exceeds these industry giants.

You can create solid or 3D figures more easily and efficiently using Catia than in other programs or in specific AutoCAD. You can also create different pieces to later assemble them and thus create figures even more complex or in greater detail. In the same way, you can make 2D drawings without much complication.

• Working on a project designed with Inventor provides a modular design platform that can quickly be configured or changed as required. This allows for the quick turn around time for the design and revision of drawings.
• We've used Inventor over the years (since 2013) and the updates and newly released versions of Inventor do not require re-training or restrict use.
• Autodesk follows an intuitive approach and users or designers who have worked on other design platforms like SolidWorks can transition easily to Inventor.

• If designing large assemblies or very complex ones, especially in the aerospace industry, CATIA is the way to go.
• The graphics are really good, and the software offers many possibilities to view a design: 2D, 3D, bird's eye view...
• Controls pan zoom rotate are easy.
