Contains controls for recording a series of transactions that contain the instructions to construct geometric and associative content. Design history is a major aspect of the development of design within a parametric model. Each change and association can be recorded as a transaction step. Using such transactions, you can group multiple changes into a single, named, logical transaction. This helps in structuring the design process. Transactions and steps appear on the Transactions list.

The Transactions dialog is accessed by selecting (Show Transactions ).
