Vector operators
OperationOperator
Multiplies, divides a vector by a real number*, /
a*[x,y,z] = [a*x,a*y,a*z]
Adds, subtracts vectors (points)+ , -
[a,b,c] + [x,y,z] = [a+x,b+y,c+z]
The following are examples of vector expressions:
A+[1,2,3] provides the point located [1,2,3] units relative to point A.
The expression
[2<45<45] + [2<45<0] - [1.02, 3.5, 2]
adds two points and subtracts a third point. The first two points are expressed
in spherical coordinates.

Enter feet and inches using the following format:
feet'-inches" or feet' inches" or feet'inches"
You can separate feet, inches, and fractional inches with a dash, a space, or
nothing. You can use any of the following syntax cases to enter valid feet-inch
formatted values:
 5' or 60”
 5'-9” or 5' 9” or 5'9”
 5'-1/2” or 5' 1/2” or 5'1/2”
 5'-9-1/2” or 5' 9-1/2” or 5'9-1/2”
 5'-9 1/2” or 5' 9 1/2” or 5'9 1/2”
To designate inches for linear calculations, entering double quotes (“) is
optional. For example, instead of entering 5'9-1/2”, you could enter 5'9-1/2.
