Enter a value directly:

1.Use your keyboard to enter a value in the data-box

2.Press the Enter key on your keyboard to update parameter to the new value

You must press the Enter key.

Enter a value as a symbolic equation:

1.Use your keyboard to enter a symbolic-equation in the data-box

2.Press the Enter key on your keyboard to update to the new value

You must press the Enter key.

Symbolic parameters for an Equation:

•Simple Arithmetic: +, –, *, /;

•Indices: ^, Sqrt();

•Trigonometric (Angles are Radians): pi, Sin(), Cos(), Tan(), Sinh, Cosh, Tansh, ArcSin(), ArcCos(), ArcTan2( ; )

Spin-Box arrowhead buttons (in the CYAN-BOX)

Top : Left arrowhead to subtract (–) the parameter-value by the Spin-Increment

Top : Right arrowhead to add (+) the parameter-value by the Spin-Increment

Bottom : Left arrowhead to divide (÷) the Spin-Increment by 10

Bottom : Right arrowhead to multiply(×) the Spin-Increment by 10

EXAMPLE:

Edit the Parameter-Value

•Click the Top & Left arrowhead: Subtract the Spin-Increment(1) from the parameter-value
Parameter-value after one click: 67.12345 – Spin-Increment = 66.12345

•Click the Top & Right arrowhead two times: Add the Spin-Increment(1)  to the parameter-value 2 x
Parameter-value after one click: 66.12345 + 2 × Spin-Increment = 68.12345

Edit the Spin-Increment

•Click the Bottom & Left arrowhead: Divide the Spin-Increment by 10
Spin-Increment value after one click: 1 ÷ 10 = 0.1

•Click the Bottom & Right arrowhead two times: Multiply the Spin-Increment by 10 2 x
Spin-Increment value after one click: 0.1 × 10 x 10 = 10

WARNING: The model re-builds each time you click the top arrowhead buttons in the Spin-Box tool. If the model is complex, there is a long time to update the model.

Double-Click

Double-click inside the data-box to hide the Spin-Box.

Double-click the data-box again to show the Spin-Box.

To see the Zero / Round / Paste / Copy  menu:

1.Right-click inside the data-box

2.Click:

•Zero - the parameter-value becomes zero(0), or the smallest possible value for the parameter-value

•Round - the parameter-value becomes the nearest value that is exactly divisible by the Spin-Increment. The Spin-Increment is below the data-box - ten(10) in the image

•Copy - to copy the parameter-value to your clipboard.

•Paste - to paste the parameter-value from your clipboard.
