Assembly Engineering Manager (D-Cubed AEM)

Realistic part positioning and motion simulation for 3D DCM-based assembly environments

Integrating the AEM into your software application enables your end-users to simulate the motion of parts more realistically whilst designing assemblies and mechanisms. This is achieved by taking account of the mass properties of parts, the motion caused by a range of engineering related forces and devices, and the interaction of parts as they collide and push each other around.

The AEM is integrated at the core of a geometric modeling application, providing end-users with motion simulation tools without the need for expensive, complex and less well integrated motion simulation modules. End-users save time and money by verifying the function of virtual assemblies and mechanisms, reducing design errors and lessening the need to produce expensive physical prototypes.

Direct interaction with the geometric model with little or no model preparation means that end-users do not have to be motion simulation experts. Unlike other motion simulation solutions, the AEM takes direct account of any 3D DCM geometric constraints, further simplifying the model preparation process.

The AEM's accuracy satisfies the rigorous demands of the engineering design process. Accurate 3D contacts are automatically computed between all permutations of points, edges and faces of any geometric type, including spline surfaces. The AEM does not use approximations such as loose solving tolerances or inherently inaccurate faceted formats that are better suited to less demanding visualization and entertainment applications.

Flexible licensing arrangements and a simple integration process enable your organization to add the AEM to your applications quickly and economically. For a step-by-step description of how the AEM is used in an application, view our product tour.

AEM Key Capabilities

Accurate Simulations with Forces and Engineering Devices

AEM provides accurate solutions on solid models from any source and does not use faceted approximations. Simulations include gravity and a variety of engineering devices, such as torques, linear and torsional springs, linear and rotary motors, conveyors and ropes.

Assembly Verification

AEM enables assembly/disassembly verification. The video shows interactive AEM sessions where a designer verifies the ability to assemble and disassemble various models.


Watch the:

Contact-based Mechanisms

AEM enables the simulation of contact mechanisms, which have previously been difficult to fully simulate in a CAD system. The video shows 3 examples of contact-based mechanisms.


Watch the:

Superiority Over Coupled Dimensions

AEM enables more realistic motion simulation compared to the use of coupled dimensions. The video shows AEM simulating gear systems physically, rather than using the simplistic and unrealistic method of coupled angles.
