I think they are separable.īrian Thompson, vice president, Creo Product Management, PTC I think in both of those cases, neither are really limited by direct modeling.

Obviously when you change a part, you want the drawing to update and you want a service assembly animation to update. You might want to have design intent because of intent ripple has a change ripple across multiple parts in the same assembly.
There is probably a finer point here, which is there’s design associativity and there’s deliverable associativity. That’s associativity by my definition, and it’s perfectly valid in a direct modeling system.Ĭhad Jackson, principal analyst, Lifecycle Insights Dimensions are edited and faces moved, or Face A is associated with Face B and, therefore, it should move also. However, there is the notion of associativity, meaning that things can happen. That’s not true in a direct modeling system. That expensive piece is you edit the first feature and you pay for all subsequent thousand features. The key difference is that it doesn’t cause a linear regeneration of the treetop to bottom. Things can be related to one another and things can be dimensionally driven and, therefore, association between the dimension and the faces. To me the word associativity with parametrics is the notion that changing one thing changes other things that are associative.

Is there associativity in direct modeling?ĭuring The Pros and Cons of 3D Modeling Paradigms webinar, one of the questions asked of our panel of experts was what is the role or definition of associativity in direct modeling? Our panelists each brought a unique perspective to that question, which I thought was worthy of sharing.ĭan Staples, vice president of Solid Edge Product Development, Siemens PLM Software Design associativity is not exclusive to history-based 3D modeling approaches.
Even small design changes cause a domino effect so users must carefully consider the impact a change will have to associated parts. The problems arise, however, when changes have to be made, a rather common occurrence at all stages of development. Though they require a lot more work, thought and pre-planning on the part of the user, history-based modeling systems provide users with a methodical, orderly and powerfully automated way to create models.
CAD software that deploys a history-based approach to modeling requires engineers to anticipate and define feature constraints, relations and dependencies, which ensures that any design change will update all related downstream geometry. When designers and engineers think about design associativity, they often think about history-based 3D modeling systems.
