example, to use the previously mentioned global variable, Phi, enter =$Phi
and press the END key.
NOTE In QuickCalc, only constants can be directly referred to by their global
variable names in the text or numeric entry boxes in windows and dialog boxes.
Use Shortcut Functions
Several sample calculator variables have been predefined and stored in the
Shortcut Functions category. These are geometric expressions that combine
CAL functions with the Endpoint Snap mode. The following table describes
the predefined variables that are available in the Variables area of the calculator.
DescriptionShortcut ForVariable
Distance between two endpointsdist(end,end)dee
Intersection of two lines defined by four end-
points
ill(end,end,end)ille
Midpoint between two endpoints(end+end)/2mee
Unit vector in the XY plane and normal to two
endpoints
nor(end,end)nee
Radius of a selected circle, arc, or polyline arcradrad
Vector from two endpointsvee(end,end)vee
Unit vector from two endpointsvec1(end,end)vee1
You can easily modify these calculator variables or create your own. For more
information, see the CAL command.
