Two-point synthesis
A four-bar linkage guides a ball from the start position to the end position. Move the end position, and the synthesis adapts the linkage in real time.

Symmetrical six-bar linkage for a door
A Watt (Ia) six-bar linkage guides a door, with its joints arranged symmetrically. In ASOMv10, the synthesis for this is built from constraints alone.

The task
Two positions, plus symmetry
A Watt (Ia) six-bar linkage guides a door from a start position to an end position. In addition, the joints are to be arranged symmetrically about a vertical axis.
What ASOM shows here
- The synthesis is built from constraints alone and locks in the positions and symmetry; additional constraints restrict individual joints in a targeted way.
- The positions remain adjustable: in the video, the vertical distance between the door and the wall changes in the end position; the angle or horizontal distance can be changed in the same way, for the start position as well.
- Colored trajectories, named end blocks in the drive control and the simulation log show whether the end position is reached or what happens instead.
Your benefits
More requirements in one synthesis
In addition to the start and end positions, you lock in further properties such as symmetry and see exactly whether the end position is reached.
Build in your own requirements
Whether symmetry, distance or angle: the synthesis adheres to whatever you define as a constraint. More on constraints
Flexible to the end
If the door positions change, you adjust the requirements instead of starting over. More on syntheses
Find errors quickly
If a change misses the end position, you see it immediately and can make targeted corrections.

Step ladder for a motorhome
Two mechanisms for the same ladder: a scissor mechanism and a parallelogram linkage. ASOMv10 designs both by synthesis and compares the required torques.

Flush-mounted door handle
A retractable handle with three specified positions. Two syntheses hold them in place while you move bearings, and ASOMv10 calculates eight drive cases at once.
