Four-bar Linkage Synthesis:
Four-bar Linkage Simulation:
App Settings and Features:
Controls
Synthesis Menu:
 |
Poses - Input and edit poses. Enter 3 poses with 2 fixed-pivot constraints, 4 poses with 1 fixed-line constraint, or 5 or more poses with no other constraints. |
 |
Fixed-Line Constraint - Draw a fixed line on which fixed pivots should lie for four-position synthesis. |
 |
Fixed-Point Constraint - Place two fixed pivots for three-position synthesis. |
 |
5 Arbitrary Poses - Synthesizes a linkage based on five random poses. |
 |
4 Arbitrary Poses - Synthesizes a linkage based on four random poses and a fixed pivot-line constraint. |
Simulation Menu
 |
RR Dyad - Touch and drag to draw an RR dyad. |
 |
PR Dyad - Touch and drag to draw a PR dyad. |
 |
RP Dyad - Touch and drag to draw an RP dyad. |
 |
Change Crank - Switch the driving dyad. |
 |
Change Branch - Switch the configuration to move the coupler to the other circuit. |
 |
Change Configuration - Switch the coupler to the other branch of the circuit. |
Animation Menu
 |
Play - Play/Pause the linkage animation. |
 |
Stop - Stop the linkage animation and reset the coupler. |
 |
Timeline - Show the animation timeline. Drag the slider to see the linkage throughout the animation. |
 |
Capture Poses - Capture the current coupler position. Captured poses can be used to synthesize new linkage solutions from the Menu icon at the top left. |
Visualization Menu
 |
Camera - Open the camera to take a picture to use as the background for the workspace. The slider controls the opacity of the background image. |
 |
Load Image - Load an image to use as the background for the workspace. The slider controls the opacity of the background image. |
 |
Clear Image - Clear the background image. |
Menu Options
 |
Menu - Open the side menu. The side menu contains examples, and allows the synthesis of linkages from captured poses. |
 |
Home - Opens the home screen. The home screen displays all your files and allows you to create new files and delete old ones. |
 |
New - Create a new file. The old file will be saved and can be found on the home screen. |
 |
Export - Export your linkage to a PDF or XML format. The exported file displays information about your linkage. |
 |
Reset View - Reset the view to focus on the workspace. |
 |
Undo - Undo the previous operation. |
 |
Redo - Redo the last undone operation. |
 |
Delete - Delete the selected element. If no element is selected, the entire linkage will be deleted (this cannot be undone!). |
