Dynamic Modeling & History-Based Approaches

There are two different approaches to 3D product development – a Dynamic Modeling based approach and a history-based approach.

With Dynamic Modeling, geometry is created similar to other systems using profiles and common machining commands. The difference is that modeling steps are freely executed and not stored and maintained in a history tree. And designers are not required to apply constraints on the profiles and resulting 3D models.

Changes to the model are independent of the steps used to originally create the model.

As a result, the model is free to develop in any way the designer chooses. This means the designer can stay completely focused on form, fit and function. Downstream changes are made by modifying the geometry itself or by modifying user-driven constraints, dimensions or relationships that have been added to the design on-demand throughout the design process. This delivers a very “dynamic” design environment where the design is free to change however the engineer chooses and in any variety of ways.

The freedom of a Dynamic Modeling based approach delivers a highly responsive design process that is not only more flexible to change, but faster as well. Speed buys time. Time to optimize a design across more design cycles. Time to release to market earlier. Time to keep the window open for design changes longer before transitioning to manufacturing.

These benefits also come to bear when working in a multi-CAD environment. Geometry is the only common element across all 3D design systems. A Dynamic Modeling based approach allows designers to interact directly with geometry rather than a history tree. As a result, geometry imported from any other 3D system is for all intents and purposes native data.

The alternative approach is history-based. A history-based modeler creates geometry through a series of 2D sketches and 3D commands that build the history tree. It is a recipe card for how the geometry is defined and requires the engineer to carefully construct the model in an attempt to allow for potential future modifications. Constraints on the profiles as well as part-to-part relationships will be required in areas where potential modifications may occur.

Modification to the model will require a very good understanding of how the model was created. This includes the original profiles, constraints, and relationships as well as the order in which they were created. It will also include how the part is related to other parts in the assembly. Once a change is initiated, the model is “regenerated” by replaying the steps in the history tree, taking into account the defined changes.

As the design becomes complex, so do the series of steps taken to create the model. Complex associations in the history tree ripple unintended changes through a model alongside intended changes--sometimes unnoticed. An engineer must work through each successive step in the history tree to correct the unintended side effects of the change.

The relationships built into the history tree may even prevent the change from being made altogether. In such cases, the only alternative to forgoing the change is to start over and remodel the part. Analyzing the history tree is a time consuming and daily step for an engineer using a history-based modeler.

The Dynamic Modeling based approach offers a more responsive and flexible design environment for rapidly changing designs under time to market pressure. Companies achieve true team design and the ability to easily repurpose existing designs on new projects. Change is predictable with a Dynamic Modeling based approach, which keeps the design window open longer before freezing a design for manufacturing.
