As we build a model, we do these steps:

STEP 1:   Add an Element

STEP 2:   Open the Element's dialog-box - see How to open a dialog-box

STEP 3:  Edit the Element's Parameters in the dialog-box

This topic reviews how to edit parameters in its dialog-box.

A typical Dialog-Box and Parameter.

The image below is a typical dialog-box. It is the Edit Dimension dialog-box.

It has one parameter and its data-box.

Dialog-box-EditParameters

In this image of the Dimension dialog-box, I have added a 'window' to highlight the parameter box.

The three parts to the parameter box are:

300

'Data-value' in the 'data-box' - this is the 'parameter' value that you apply to the element.

10

Spin-Increment value - you can edit this with the arrows at the bottom of the Spin-Box tool


Spin-BoxArrows

Spin-Box arrowheads [top and bottom arrowheads to the left and right]

How to edit parameters in a dialog-box.

There are three different methods/procedures you can use to edit a parameters value in a dialog-box:


Method 1: Use your Keyboard

Dialog-Dimension-EditDirectly

Enter a data-value directly:

1.Enter the data-value with your keyboard
2.Press the Enter key on your keyboard to update to the new value

You must press the 'Enter' key (also called the Return key) to update the value.

Dialog-Dimension-SymbolicEqtn

Enter a 'symbolic equation':

1.Enter an equation with your keyboard
2.Press the 'Enter'  on your keyboard to update the value

You must press the 'Enter' key (also called the Return key) to update the value.

Symbolic parameters:

Simple Arithmetic: +, –, *, /;
Indices: ^, Sqrt();
Trigonometric [Angles are Radians], pi, Sin(), Cos(), Tan(), Sinh, Cosh, Tansh, ArcSin(), ArcCos(), ArcTan2( ; )

Method 2: Use the 'Spin-Box' tool

Dialog-Dimension-UsingtheSpinBox

Spin-Box arrowhead buttons [in the blue-box]

3s Top : Left arrowhead to decrease the data-value1s-red by the Spin-Increment2s

3s Top : Right arrowhead to increase the data-value1s-red by the Spin-Increment2s

4s Bottom : Left arrowhead to divide the Spin-Increment2s by 10

4s Bottom : Left arrowhead to multiply the Spin-Increment2s by 10

Edit the Data Value

Click the Top : Left arrowhead to decrease the data-value1s-red. [Data-value after one click: 67.12345 Spin-Increment[1] = 66.12345 ]
Click the Top : Right arrowhead to increase the data-value1s-red [Data-value after one click: 67.12345 + Spin-Increment[1] = 68.12345 ]

Edit the Spin-Increment

Click the Bottom : Left arrowhead to decrease the spin-increment2s [Data-value after one click: 1 ÷ 10 = 0.1 ]
Click the Bottom : Right arrowhead to increase the spin-increment2s [Data-value after one click: 1 × 10 = 10 ]

WarningWARNING: The model re-builds each time you click the top arrow buttons.


DoubleClickSpinBox

< >

'Double-Click'

DoubleClickSpinBox-2

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

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


Method 3: Use the Zero/Round contextual menu

Dialog-Dimension-ZeroRound

To use: 'Zero' or 'Round' data-value:

1.Right-click inside the data box

The 'Zero / Round' contextual menu shows.

2.Click:
Zero: value becomes = 0.
Round: value becomes nearest value that is exactly divisible by the Spin-Increment.
