Autodesk inventor has a rather practical functionality called the “Derive” functionality. What the Derive functionality does is lets you create a new part to reference an existing part’s solids, surfaces, parameters, work geometry, sketches etc.
The main benefit of this is to be able to create a model that has various parts linked to a base part, then when changes are made to the base part the other linked parts will update as well, this is handy because if you want to make various variations of one part you can also break the link from the derived base part to the derived part. Enabling you to make different parts with different geometry.
A Derive assembly is a new part that references an existing assembly. You add to the new derived part or assembly, when you add new features to the base component or when the base components features are edited, the derived part updates with the changes.
There are two methods in which to create derived parts. The “Push” method and the “Pull” method. We will go through the “Pull” method in some more detail.
One thing to note is that the Derive window that opens, is different depending on whether you
are deriving from a part of from an assembly. This just means that the selection options available and the window layout will be different depending on what you are deriving from.
I’ll go through the window of the Derive Part, showing the most commonly used buttons and then do a part derive example.
