Many More Ways to Learn GenerativeComponents
GenerativeComponents is Self-Documenting
As you create new nodes, GenerativeComponents lets you record them in a series of transactions. Each of these steps is editable: you can change what they do, they can be renamed, and rearranged to explain a design. You can also choose to enable auto-recording of transactions and not have to record them manually.
The easiest way to learn GenerativeComponents is by looking at existing designs. You can play through the transactions in a file to understand them, then copy and modify them to suit your needs. There are many GenerativeComponents files available on the Internet, from Bentley, and many other GenerativeComponents users. A good place to start is: http://communities.bentley.com.
