Form: CSI Calculator
Use the ETABS Calculator feature to assist with mathematic operations in forms that accept generic entry. That is, when a command accesses a form that requires input of values in edit boxes, use the Calculator feature to calculate the values to be entered.
Access the Calculator feature as follows:
A form that requires generic entry must be displayed. For example,
Select a line object and click the Assign menu > Frame Loads > Distributed command to access the Frame Load Assignment - Distributed form.
Click in the first Distance edit box in the Trapezoidal Loads area of the form.
To access the CSI Calculator form, hold down the shift key and press the Enter key, or hold down the shift key and double click the left mouse button.
