\"3ddcm<\/span>\ufeffMillions of designers and engineers will benefit from the latest versions of D-Cubed components that shipped to CAD, CAM and CAE software vendors. Here we take a deeper dive into the world of bounded constraint solving<\/EM>, that was made possible with new technology in D-Cubed 3D DCM. Version 50.0 enables new part, assembly design and simulation scenarios where geometric constraints permit a range<\/EM> of model configurations.<\/SPAN><\/P>
\n

Some background<\/EM> – prior to version 50, it was possible to specify upper and lower limits for distance and angle dimensions (\u201cbounded dimensions\u201d). This was ideal for defining a permitted range of linear\/angular positions for objects in a 3D scene; for example to model the range of motion in certain types of joints.<\/P>
\n

The new stuff<\/EM> \u2013 3D DCM version 50 enables applications to build inequality relationships and link them to the model. For example, consider the expression c1 <= a <= c2<\/STRONG>. Variable a can be linked to any<\/U> dimension value (curve length, radius, etc.). c1<\/STRONG> and c2<\/STRONG> then determine the permitted range for the dimension value. This flexible system opens up a whole new range of 3D modeling scenarios. For example, to impose a constraint on the design of a part, such as the range of lengths of a routing cable, or the minimum wall thickness in a moulded part.<\/P>
\n

Dimensions and constraints on the model are solved simultaneously along with any inequality relationships. For example, an application could create an inequality relationship that limits the cross-sectional area of a part between two defined values. Any design modifications – changing a dimension value, or interactively dragging geometry \u2013 would be limited to those that do not violate the prescribed limits.<\/P>
