This course introduces you to the interface and key processes of Inventor, the parametric design system from Autodesk. Author John Helfen covers sketching, part modeling, assemblies, and drawings. These tasks work in conjunction, allowing you to create parts and assemblies and document them in a way so that the manufacturing process proceeds faster and more efficiently.
On the screen you can see the dimensions that we created. One of the things you might notice is that the dimensions are only to two decimal points of precision. Now typically I wouldn't recommend jumping in and changing a lot of settings in the drawing, especially without talking to a CAD manager, because a lot of these standards are set. But I know that the precision is something that people might want to change right out of the gate. I'm going to take a minute to show you how to do this so that you can ensure that your designs are documented properly for manufacturing. To make this change, we're going to go to the Manage tab on the Ribbon bar.
Under the Styles and Standards panel we're going to select Style Editor. Now there's a lot of settings here, and we're not going to through all of them, we're most specifically looking at Dimensions. Even more specifically than that, we're looking for the default ANSI Dimensions. Depending on the type of standard you've installed on your system, these may be slightly different but you're going to look for the defaults anyway. Here in the Linear section we have the Precision called out as two decimal points. We're going to simply select the dropdown list and pick 3.123, which indicates a three decimal precision, and we're going to select Done.
Inventors is going to ask us to save our Edits, and when we do that you can see that the change has been reflected in our drawings. Again, I wouldn't recommend changing these settings in a commercial environment without talking to your CAD manager, but hopefully this will allow you to begin documenting your designs properly for manufacturing.
