Dynamic modeling

from Wikipedia, the free encyclopedia

The approach of dynamic modeling (English Dynamic Modeling ) is a CAD technology for the creation and modification of solid models . Another term for this is also the expression of direct modeling (direct modeling). Models are not developed and changed using parameters, but rather through direct specification of the geometry concerned. For example, a hole is selected directly on the model and moved, reduced, enlarged or deleted. Areas and geometry elements can be recognized and reused as features regardless of their original definition.

import

Imported 3D models from other CAD systems are treated as if they had originally been created in the CAD system, which includes a dynamic modeling approach. The models can be modified and expanded: Geometry features are also recognized and can be modified. Parameters and the history of the model from the original system are not transferred via the standard interfaces STEP ( Standard for the exchange of product model data ) and IGES , but they are not required for dynamic modeling either.

Should the case arise that a design intention is to be defined and retained by means of a parameter, this can be done at any time - also on the imported model: The diameter of a hole can, for example, be defined depending on its depth, or the position of the groove always remains the same Value for edge A. In contrast to so-called parameter-based systems, this parameterization does not take place as part of the model creation, but rather serves to clearly define a few design constraints.

Learn

Learning about CAD systems based on a dynamic modeling approach is limited to the commands and the user interface and to a basic understanding of solids. Technologies such as parameterization, modification of the model history and constraints do not have to be understood.

Examples

OneSpace Modeling software from CoCreate is a 3D CAD system that uses a dynamic modeling approach .
