D-Cubed: Latest release of the PGM, Version 51.0
Released March 2007
D-Cubed announces the latest release of its Profile Geometry Manager (PGM), the component that adds extra productivity tools to 2D DCM-based sketchers. New functionality specific to version 51.0 is listed below. A full product description can be found here.
Broad enhancements to offsetting capabilities
A key capability of the PGM is the creation and management of offset profiles comprising any type of 2D geometry including NURBS curves. Of major significance is the tight interaction of the PGM with a 2D DCM sketch, where dimensions and constraints can be applied freely to any geometry in the profile, including the offset geometry. Subsequent modifications to the dimensioning scheme result in automatic updates of the offset profile with correct trimming and capping of the offset geometry.
Version 51 introduces new functionality and enhances reliability and performance with offset profiles. Highlights include:
- Extended trimming capabilities. The PGM automatically trims unrealistic intersecting geometry in an offset loop. Version 51 enables trimming in a range of challenging special cases that were not fully supported in previous releases.
- Solving multiple offset distances. The PGM now enables applications to create and modify offset loops where the value of the offset distance varies between different edges in the loop. Trimming is also supported on such offset loops for common cases. An example is illustrated below:
- Improvements to dragging geometry. The PGM supports dragging operations, where geometry can be interactively repositioned in accordance with existing sketch constraints, including any specified offset distance. Version 51 enhances this dragging capability, enabling users to more rapidly evaluate conceptual modifications to a sketch which contains offset loops.
- Enhanced support for offsetting evaluated parametric geometry. The PGM provides full support for offsetting NURBS curves. Applications can also represent freeform geometry using a parametric definition that will be evaluated by the PGM. In previous releases, the PGM could fail to offset the parametric curve correctly if its definition was modified by the application. Version 51 addresses this issue, resulting in improved reliability when offsetting evaluated parametric geometry.
About the PGM
The Profile Geometry Manager (PGM) enhances the productivity of 2D DCM based applications, enabling a range of advanced variational sketching operations. This is achieved by working directly with higher level geometric data structures and automatically handling a wide range of design changes. Examples including offsetting loops whilst inserting, extending and trimming edges as required, or adding constraints to loops rather than to individual edges.
