MechDesigner 12... engineered to move.

MechDesigner gives you the tools to design and model multi-axis machines, with multi-link mechanisms, cams, gears, pulleys all with complex motions.

Paraphrasing someone: "MechDesigner does not stop you doing stupid things, as that would also stop you doing clever things."

Why MechDesigner?

There are many reasons to buy MechDesigner.

Design and optimize motions with our best-in-class, integrated motion design tool - MotionDesigner.
Design all of the mechanisms that you need for a machine, and synchronize them to a machine 'clock'.
Run at 'machine speed', or 'micro-step' the model to scrutinize all machine interactions.
Edit parameters 'on-the-fly' with extremely fast and exact simulations and analyses.
Use Design-Sets to edit and watch parameters update immediately as you optimize your design.
Add any number of mechanisms.

Kinematic and Force Analysis:

Absolute and relative, linear and angular, position, velocity and acceleration, of all machine points and parts.
From a defined tooling motion, automatically derive the cam-follower motion with inverse-kinematics.
Analyze force and torque data at each joint to find the correct bearing, linear guide, and servomotor.
Plot any number of graphs, of any design parameter.

Cam and Servo Calculations:

Automatically calculate cam-coordinates of plate, groove, conjugate, barrel, cylindrical and globoidal cam types.
Export cam-coordinates directly to SOLIDWORKS®
Save cam-coordinates as STEP file [R13+]
Servomotor, four-quadrant 'Torque-Speed' & 'Duty-Cycle' Analysis.
Servomotor motion profiles.

Tools to:

Mechanism Synthesis with the constraint based sketch-editor.
Reverse Engineer Cams, and make the cam-follower's motion better than the original motion
Design Scrolls/Feedscrews.
Design gear-trains, pulleys, rack and pinions.
Import SolidWorks® Parts and Assemblies.
Export SolidWorks® cams as STEP files.

When you can do all of this, and more, it is easy to analyze designs, remove design problems, see new design opportunities and engineer the cams you need to make it happen.

When you use MechDesigner, we guarantee (almost) it is possible to improve the performance of your multi-axis machine. Why not let the design engineers at PSMotion review your design. If necessary, we will sign your NDA [Non-Disclosure-Agreement].

To get the most from MechDesigner & MotionDesigner, you must do the tutorials. The tutorials show you how to use each command with real design applications. You will learn the 'rules' for each command. After you complete the tutorials, you will be able to work faster and much more efficiently.

Rapid Start Tutorial - a very quick start, for those who do not want to ask 'too many questions'.

Complete Reference and Installation Help

It is important that you also look at the complete references to MechDesigner and MotionDesigner. It gives more details of each parameter in each dialog-box.

Useful Design Information

Links to other Help File Formats

There are other help formats.

In particular, it is important that you download and install the 'Local-Help' so that you can show with your F1 key the contextual help for each parameter.

MechDesigner: CHM format

The F1 key (or ALT+F1 on a laptop) will give contextual help when you download and save this file to:

C:/ProgramData/PSMotion/MD12 XXX*64/MechDesigner/

* XXX= TRL for a Trial Installation, XXX=PRO for a Professional installation.

If you cannot see ProgramData show it with Start > Control Panel > Folders > View tab | Click: Show Hidden Folders.

MechDesigner: PDF format

Warning - approximately 1200+ pages.

Also, as always, there are bugs in MechDesigner. See here for those bugs we are yet to resolve.
