Combo Box
With a combo box, you can create a selectable list of items to calculate. When you select an item, Mathcad uses the corresponding value for calculating all the dependent regions. For items with multiple values, Mathcad returns a column vector. When you change your item selection, the calculations update to reflect the new item values. Combo box selection settings are saved between Mathcad sessions.
