Edit edit a value in a data-box.

The data-boxes are the same in MechDesigner and MotionDesigner.

We can use the Dimension dialog-box to show the tools and different procedures you can use to edit a parameter in a data-box.

The Data-Box in a Dialog-Box

The Data-Box in a Dialog-Box

In the image, I have added a 'window' to show the 'Dimension' data-box in the Dimension dialog-box. It is typical of all data-boxes in MechDesigner and MotionDesigner.

The data-box has three parts:

68.24987846

'Data-value' : this is the 'parameter'.

10

 Spin-Increment value box


Spin-BoxArrows

Spin-Box arrowheads

Three different procedures to edit a data-value:

Enter a value directly with your keyboard.

Enter a value directly with your keyboard.

Enter the data-value directly:

1.Enter the value in the data-box with your keyboard
2.Press Enter to update the value

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

Enter an Equation in the Data-Box

Enter an Equation

Enter the data-value as a 'symbolic equation':

1.Enter the equation
2.Press Enter to update the value

You must use the 'Enter' key to enter the value.


Simple Arithmetic: +, –, *,  ∕;
Powers: ^, Sqrt();
Trigonometric: Angles are Radians,
oSin(), Cos(), Tan(), pi
oSinh, Cosh, Tansh
oArcSin(), ArcCos(), ArcTan2( ; )
Use the Spin-Box in a Data-Box.

The Spin-Box controls in a Data-Box.

The to use the Spin-Box tool, we should first look at these two values:

1s-red Top-Row: data-value: = 67.12345

2s Bottom Row: Spin-Increment value: = 1

The Spin-Box tool is inside the Blue box. It also has two rows:

3s : Data-Increment: Click the Left or Right arrow button to change the data-value by the spin-increment.

4s : Spin-Increment: Click the Left or Right arrow button to change the spin-increment value by a multiple of 10.

You cannot enter your own Spin-Increment.

Use the Spin-box tool - the Blue-Box:

Click the Top arrow-buttons3s to change the Data Value1s-red value by the Spin-Increment :
Click the top - left arrow button, and the data-value1s-red will become [67.12345 Spin-Increment] = 66.12345, then 65.12345, 64.12345,...
Click the top - right arrow button, and the data-value1s-red will become [67.12345 + Spin-Increment] = 68.12345, then 69.12345, 70.12345,...
Click the Bottom arrow-buttons4s to change the Spin-Increment :
Click the bottom - left arrow button, and the spin-increment becomes 0.1. then 0.01, 0.001, 0.0001,...
Click the bottom - right arrow button, and the spin-increment becomes 10, then 100, 1000, 10000,...

WARNING : The model re-builds each time you click the arrowheads of the top arrows in the spin-data box!

When the MechDesigner model has many 'steps, and the model is complex, then the model may need seconds to update each time you click the spin-box.

See MechDesigner > Edit menu > Machine Settings > Cycling Separator  number-of-steps

In this case, use your keyboard to enter a data-value, or reduce the 'number-of-steps', or de-select the Auto-Update, or both.

Double-Click

MD-SpinBoxNot

Double-Click the dimension box to Toggle the Spin-Box tool on and off.

The 'Zero/Round' menu

The 'Zero/Round' menu

'Zero' or 'Round' data

1.Right-click inside the data box

The 'Zero and Round' contextual-menu shows.

2.Click:
'Zero' : to make the data value Zero!
'Round' : to change the data to the nearest value that is exactly divisible by the Spin-Increment
