AutoCAD vs. CATIA vs. ExtendSim CP

Once again, for jobs/companies where you are doing a lot of design and modelling of tanks, pipework or filling machine or basic electronics its fantastic as a 3D and 2D modelling tool, however once again when it comes to testing these actual products in the real world, I feel like AutoCAD is let down by its clunky fitting and spec management and also in very limited in-house engineering simulations.

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

• Compatibility of different file formats, and also exports to different file formats.
• CLI Commands as well as internal functions which are exposed can be used for automation of various tasks.
• The new 2025 comes with .NET Core support which helps AutoCAD to connect with Cloud based features.

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

• User Interface Customisation: AutoCAD's user interface could benefit from more robust customisation options. Allowing users to rearrange toolbars, menus, and panels according to their specific workflows and preferences would enhance productivity.
• Enhanced 3D Modeling Tools: While AutoCAD is capable of 3D modeling, it's not as intuitive or feature-rich as dedicated 3D modeling software. Streamlining the process and adding more advanced modeling tools would be a welcome improvement.
• Enhanced Collaboration and Version Control: AutoCAD could improve its collaboration tools, such as real-time editing and version tracking, to facilitate smoother teamwork, especially in multi-disciplinary projects.
• Intelligent Object Libraries: AutoCAD could benefit from an expanded and more intelligent library of standard objects and components. This would save time for designers who often have to create custom components from scratch.

• 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.

Because rarely we [would] rather wait for a whole year to update, sometimes the new updates don't bring many new features and we are still ok with the current version. Also the change of interface is always something that takes time for every partner in the company to get comfortable with. So those are the main reasons we may want to keep the same version.

It is very usable once you understand the program. I believe there is room for improvement in the 2D to 3D modeling capability. We have to use other apps to 3D model and that can be time consuming and sometimes AutoCAD doesn't transfer work that well between apps. They can improve there.

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

AutoCAD has the issue of crashing or slowing down the design procedure once a heavy design that includes several disciplines or multiple families/blocks is involved. Customer services gets the feedback from the crash reports but this issue seems like it has never been addressed in the software updates past several years.

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.

the implementation was realy easy , to set up our workstation we pay for the licenses we are about to use , there was a little bit of delay to get the payment processed to receive the serial but after that the install runs without any problem , so you can fell secure there will be not issue with the implementation.

I use Revit far more than I use AutoCAD. AutoCAD is great for simple linework, but even then I will often create the lines in Revit and then export to AutoCAD for final touches and printing. AutoCAD is a bit easier for large-format prints, which is why I almost always end up using it after starting in Revit.

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.

• As an educational institute there are no overall business objectives.
• As a negative, the licensing is expensive and we have to limit the number of computers we put it on.
• As a positive, many of our students will have a leg up when entering into programs or companies that use this software.

• 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.
