Arithmetic Notation for Numerical Input by the User

Home > 02 Basic Tools > Arithmetic Notation for Numerical Input by the User

The following options are available for defining a point in space and inserting numerical input.
Input a mathematical formula and let the system calculate its value.
Indicate a sample entity from which dimensions will be retrieved.
Use a combination of these options.
The existing means of defining a point (dx, ax, pxy, etc.) can be included in the formula.
Using a Complex Formula
You can provide a complex formula and the system will calculate its numeric value. The following arithmetic operations can be used:
OperatorSymbolOperatorSymbol
Brackets( )Sinesin(n)
Add+Cosinecos(n)
Subtract-Tangenttan(n)
Multiply*Cotangentcotan(n)
Divide/Square Rootsqr(n)
Powerpwr(n)

For example, to specify a numeric value, type dx 7*sin (34.5), and the system will calculate the value.
Using Dimensions of an Indicated Entity
Provide a numeric value by specifying the type of value, and then indicating the entity from which it is read.
All the value type options are specified by using the prefix "&" on the input line, which implies indication of a sample entity from which the dimensions will be taken. You can also include absolute, relative and polar prefixes in the formula (ax, dx, pxy, etc.).
Value types:
Length of linear entities - &l
Radii of arcs and circles - &r
Diameter of arcs and circles - &d
Angle of arcs and circles - &a
For example, when you draw a line, you are prompted to specify the next point. Type dx &l, the system asks you to indicate a linear entity. Once the indication is given, the next line will be extended along the x axis by the length of the entity indicated.
NOTE When you indicate a complex entity, the value of the length (radius/angle) is taken from the specific line that you indicated in this entity.
