Mathcad Prime 7 introduces combo boxes, allowing you to control calculations in your worksheet with easy to create drop-down menus of variable definitions. Pre-define variables and variable values associated with calculations in which you might want to consider more than one variable. Once the variables are populated in the drop-down menu, you can easily recalculate your equations by simply selecting the desired drop-down option.
