More recently I have seen a large demand to customize the information within iProperties. One great way to do this is take advantage of the expressions that can be created in iProperties using either other iProperties or parameter values that have been created during the modeling process. Using Parameter values in expressions in iProperties can allow a user to automate such common iProperties such as description. The keys to doing this successfully are to carefully name your parameters ( User Parameters work best), export those parameters so that they will be shown on the custom tab of the iProperties, and create the correct expression. There is a simple example here in the video to get you started.
