Join Thom Tremblay for an in-depth discussion in this video Understanding the key differences between AutoCAD and Inventor, part of Migrating from AutoCAD to Inventor.
- In this movie we will look at the foundations of Autodesk Inventor and how it thinks differently than AutoCAD. It's important to understand how Inventor wants to work because trying to use it like AutoCAD can not only be frustrating, it will limit your productivity and how enjoyable it is to use it as well. The key difference between AutoCAD and Inventor is how it generates drawings. AutoCAD is geometry-based. Because of this, the lines in .rx can be formed to make anything you want, whether it's a building or a mechanical part. Inventor is more industry-focused.
Therefore it understands how things really go together. Taking a closer look at this drawing, this is something that AutoCAD easily could have made, right down to the dimensions, the weld callouts, the annotation, but the way Inventor works is slightly different. What I mean by that is Inventor works from a model. For example, if I go to the 3D model, I can see where there's a weld holding these two components together. That weld actually gives me the information for my annotation.
The size of these three-dimensional models gives me the information for my 2D annotation. If we were to edit one of these components, (mouse clicking) perhaps change its size, (mouse clicking) (mouse clicking) will not only be affecting the 3D model. When we turn back to our drawing, we'll see that our annotation updates to reflect the change in the model without us having to make any changes.
To do the same change in AutoCAD, you would have to change the position of multiple lines, arcs, hidden lines, dimensions and several drawing views, perhaps across several drawing pages. In Inventor, the update happens automatically. AutoDesk Inventor takes a different approach than AutoCAD at nearly every level, so it's best for an experienced AutoCAD user to free your mind when you start to work with Inventor and try not to force it to behave like AutoCAD.
