There are three different methods to edit a parameters value.

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 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.

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 arrow buttons (in the blue-box)

Top : Left arrowhead to decrease the data-value by the Spin-Increment

Top : Right arrowhead to increase the data-value by the Spin-Increment

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

Bottom : Left arrowhead to multiply the Spin-Increment by 10

Edit the Data Value

•Click the Top : Left arrowhead to decrease the data-value. (Data-value after one click: 67.12345 – Spin-Increment(1) = 66.12345 )

•Click the Top : Right arrowhead to increase the data-value (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-increment (Data-value after one click: 1 ÷ 10 = 0.1 )

•Click the Bottom : Right arrowhead to increase the spin-increment (Data-value after one click: 1 × 10 = 10 )

WARNING: The model re-builds each time you click the top arrow-buttons of the Spin-Box tool

Method 3: Use the shortcut-menu

dialog-dimension-zeroround

1.Right-click inside the data box

The Zero / Round / Copy / Paste shortcut menu shows.

•Zero: - do not use for dimensions

•Round: change the value to the nearest value that is exactly divisible by the Spin-Increment.

3 Methods to Close the Part-Editor

To close the Part-Editor, use one of these 3 methods:

1.Double-click the Y-axis* or a sketch-element

or

1.Cancel Edit Part in Part-Editor to the left of the graphics-area

or

1.Right-click in the graphics-area

2.Click Edit Part in Part-Editor icon in the shortcut menu

* Why the Y-axis?

Because, if you double-click the X-axis, you may actually double-click the CAD-Line and open the CAD-Line dialog.

When you return to the Mechanism-Editor:

The X-axis and Y-axis are small.

Note:

•The Part is 70mm long.

•Base-Value of the Motion-Dimension is 75°.
