If your work mainly involves 2D drafting or you need a more affordable and less resource-intensive software, AutoCAD could be better for you.

In summary, neither software is inherently “better” than the other. The best tool for you depends on your specific needs, the nature of your projects, your budget, and system resources.

2. What is the difference between Autodesk and AutoCAD?

Autodesk is the company that develops several software products, and AutoCAD is one of these products. Autodesk Inc., founded in 1982, is a multinational software corporation that specializes in making software services for architecture, engineering, construction, manufacturing, media, education, and entertainment industries.

AutoCAD, developed and sold by Autodesk, is a computer-aided design (CAD) software used by architects, engineers, and construction professionals to create precise 2D and 3D drawings. It was the first significant CAD program on the personal computer and is the flagship product of Autodesk.

In short, Autodesk is the company, while AutoCAD is a software product created by Autodesk. They are related but serve different roles: one is a corporate entity, and the other is a software tool used in various industries.

3. Is Inventor compatible with AutoCAD?

Yes, Autodesk Inventor is compatible with AutoCAD in several ways. Inventor can import and export AutoCAD files in DWG format, allowing for seamless data exchange between the two software. This means you can design a part in Inventor, export it to AutoCAD for further detailing, and then bring it back into Inventor.

Also, Inventor has an “AutoCAD-like” interface option, which can make AutoCAD users more comfortable when transitioning to Inventor. This feature harmonizes the user experience between the two platforms.

Lastly, Autodesk provides an option for interoperability between Inventor and AutoCAD through the “AnyCAD” feature. AnyCAD allows Inventor users to maintain an associative link to native AutoCAD data, facilitating real-time collaboration.

4. What is Autodesk Inventor good for?

Autodesk Inventor is primarily used for 3D mechanical design, design communication, tool creation, and product simulation. It excels in creating detailed and accurate 3D models of parts and assemblies, making it a popular tool in the manufacturing industry.

Inventor’s parametric modeling capability is another strong suit. It allows designers to maintain relationships between parts and assemblies, change parameters, and automatically update the design accordingly. This feature streamlines the design process and boosts productivity.

Inventor also stands out in its ability to perform complex simulations. It allows engineers to test and validate their designs within the software environment, reducing the need for physical prototypes. In turn, this capability can significantly speed up the product development process and reduce costs.

5. Do engineers use AutoCAD or Inventor?

Both AutoCAD and Inventor are used by engineers, but the specific type of engineering work often determines which software is preferred. AutoCAD is widely used by civil engineers for creating architectural plans and blueprints. It’s also popular in the electrical engineering field for designing circuit layouts.

On the other hand, mechanical engineers often prefer Inventor because of its advanced 3D modeling capabilities and specialized tools for designing mechanical parts and assemblies. Inventor also provides robust simulation tools that allow engineers to test their designs under real-world conditions, a feature highly beneficial for product development.

However, it’s important to note that the use of AutoCAD or Inventor is not strictly tied to a specific engineering discipline. Some mechanical engineers may find AutoCAD sufficient for their needs, while some civil engineers might use Inventor for certain projects. The choice of software depends on the specific requirements of each project and personal preferences.

6. Can you edit DWG in Inventor?

Yes, Autodesk Inventor can import and edit DWG files, which is the native file format for AutoCAD. This capability facilitates a seamless exchange of data between the two software. Once a DWG file is imported into Inventor, you can manipulate the 2D data or use it as a basis for creating 3D models.

Inventor also supports “DWG Underlays,” allowing you to insert AutoCAD DWG files into an Inventor part file as a sketch symbol. You can then use these 2D sketches as a reference for creating 3D models.

Furthermore, Inventor maintains an associative link to the original DWG file. This means that any changes made to the DWG file in AutoCAD will automatically update in Inventor, ensuring data consistency across the two platforms.

7. Is Inventor CAD free?

Autodesk Inventor is not free, but Autodesk offers a free trial of Inventor for you to test the software before committing to a purchase. The free trial typically lasts for 30 days and provides full access to all features and capabilities of the software.

For students, educators, and academic institutions, Autodesk provides a free educational version of Inventor. This version is fully functional and can be used for learning and teaching purposes. However, designs created using the educational version are not licensed for commercial use.

Autodesk offers various subscription plans for Inventor, including monthly, yearly, and multi-year options. Pricing details can be found on the official Autodesk website.

8. Is Inventor good for 3D modeling?

Yes, Autodesk Inventor is an excellent tool for 3D modeling, especially for mechanical design. It offers a comprehensive suite of tools for creating and editing 3D models, including parametric and direct modeling, freeform, and surface modeling.

Inventor’s parametric modeling capability is particularly noteworthy. It allows designers to define relationships between features and parts, enabling changes to be automatically propagated throughout the design. This feature significantly streamlines the design process and increases efficiency.

Furthermore, Inventor provides advanced assembly modeling capabilities. Designers can create complex assemblies with thousands of parts, manage assembly constraints, and perform interference checks. With Inventor, you can accurately represent and visualize how different parts will fit and work together in a final product.

9. How do I convert Autodesk Inventor to AutoCAD?

To convert an Autodesk Inventor file to AutoCAD, you can use the “Export” function in Inventor. Here are the steps:

  1. Open your Inventor file.
  2. Click on “File” in the top left corner.
  3. Select “Export” from the dropdown menu, then click on “CAD Format.”
  4. In the Save As dialog box, choose “AutoCAD DWG Files” in the Save as type dropdown menu.
  5. Choose the location to save your file, provide a name, and click “Save.”

This process will convert your Inventor file into a DWG file, which you can then open and edit in AutoCAD.

Converting a 3D AutoCAD model to Inventor involves importing the AutoCAD file into Inventor and then manipulating the data as necessary. Here are the steps:

  1. Open Autodesk Inventor.
  2. Click on “Open” in the top left corner.
  3. Navigate to your AutoCAD file, select it, and click “Open.”
  4. In the Import dialog box, ensure that the file type is set to AutoCAD DWG, then click “OK.”

This will import your 3D AutoCAD model into Inventor, where you can then work on it as you would with any other Inventor model. Remember that while the import process is usually straightforward, the complexity of the AutoCAD model may affect how well it translates into Inventor.

11. What CAD format does Autodesk Inventor use?

Autodesk Inventor uses its proprietary file format with the extensions .ipt for part files, .iam for assembly files, and .idw or .dwg for drawing files. These file formats are designed to take full advantage of Inventor’s advanced 3D modeling capabilities.

However, Inventor also supports a wide range of other file formats for import and export. This includes common CAD formats such as DWG (AutoCAD), STEP, IGES, and STL, among others. This ensures that Inventor users can easily exchange data with users of other CAD software.

The specific format you should use depends on your needs. For example, if you’re collaborating with someone using a different CAD software, you might want to use a neutral file format like STEP. If you’re preparing a model for 3D printing, you would likely use STL.


AutoCAD and Autodesk Inventor are both powerful CAD tools, each offering its unique advantages. AutoCAD is renowned for its versatility, making it the go-to software for professionals needing to create precise 2D and basic 3D designs. Conversely, Autodesk Inventor is preferred for its advanced 3D modeling capabilities, especially for mechanical design and simulation.
