A parameter-value in a dialog

In this example, the parameter is Dimension in the Dimension dialog, and the parameter-value is 300.

In the image, I have added three colored boxes

300

Parameter-value - the value, in the data-box, to edit and apply to the element.

Spin-Increment - the change to the parameter-value each time you click a Spin-Box arrow - see Spin-Box tool

Spin-Box tool: see more Spin-Box tool

Note: If you cannot see the Spin-Box tool:

Double-click with your mouse in the Parameter-value box

How to edit parameters in a dialog.

There are three different methods you can use to edit a value in the parameter box.

Method 1: Keyboard

Dimension dialog-box

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 the parameter to the new value

You must press the Enter key.

Equation in Dimension box

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( ; )

Method 2: Spin-Box tool

Spin-Box tool

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 (÷) by the Spin-Increment

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

EXAMPLE:

Edit the Parameter-Value

•Click the Top & Left arrowhead: Subtract the Spin-Increment(1) from the parameter-value
Parameter-value after one click is 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 is 66.12345 + 2 × Spin-Increment = 68.12345

Edit the Spin-Increment

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

•Click the Bottom & Right arrowhead two times: Multiply the active Spin-Increment by 10 2 x
The active Spin-Increment value after two clicks is 0.1 × 10 × 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.

Method 2A: Show / Hide the Spin-Box
