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.
In a previous movie we learned how to create general dimensions and adjust the precision of those dimensions. In this movie we want to focus on how to accelerate the annotation process by using baseline dimensions. To start this process we're going to go to the Annotation tab, and in the Dimension panel you can see along with our general dimension we have Baseline, Ordinate, and Chain dimensions. Now all three of these types of dimensions work in very similar fashion, that's why I'm going to focus simply on baseline here. I'm going to launch the Baseline command, and I'm going to zoom in on the view in the bottom corner of the drawing.
Within the Baseline command, Inventor is now ready for us to select specific pieces of geometry we want to dimension in this view. I'm going to start by selecting the bottom of the part, and I'm going to work my way up through the view, selecting specific items I want to create dimensions for. Once I've selected all those items, I can simply right-click, select Continue, and Inventor will create all of the dimensions in one action. Now while placing the dimensions, it does work with the general dimensions. I do have the ability to snap to my increments for organization purposes, and here I'm going to find a location that I like, I'm going to left-click to place those dimensions, and then I'm going to right-click to actually create those permanently.
You can see that with just a few clicks Inventor has created a number of dimensions in one action, which should help speed the design process. The one thing you might notice if we zoom out a bit is because we added all these dimensions in one action, they extend a little too close to the view to the right. If we were to add dimensions to this, they might overlap. To fix this, we can simply hover over the view, left-click and drag to reposition the view and the dimensions all move because they're linked to that view specifically.
As you can see, the Baseline dimensioning is a great way to speed the Annotation process.
