In greatest in quantity solid modeling CAD systems, knowledge of the history of the design is necessary to avoid unanticipated side-effects when making changes. With dynamic modeling, local geometry and topology changes can be made independently of the mould creation at any time, using the two direct and dimension-driven methods. The core constituents enabling dynamic modifications are the tool material substance and the relation solver.

HP Precision Engineering SolidDesigner (PE/SolidDesigne) is a 3D solid modeling design plan based on the ACIS[R] Kernel (see "About Kernels" in succession next page). It provides the geometric archetype needed by design workgroups in production development environments. The system's dynamic modeli technology gives the designer the freedom to incorporate changes at any time and at any stage of production development, without dependence on the history of the consequence design.

HP PE/SolidDesigner is a member of the HP Precision Engineering connected views (PE/Systems) product family. Today, HP PE/System consists of:

* HP PE/SolidDesigner for solid modeling * HP PE/ME10 for 2D design, drafting, and documentation * HP PE/ME30 for 3D design * HP PE/SurfaceStyler, an engineering styling application integrated with HP PE/SolidDesigner * HP PE/SheetAdvisor, a sheet-metal design-for-manufacturability application * HP PE/WorkManager for effect data and workflow management * HP PE/DDS-C for electrical method design * HP PE/Complementary Application Program (CAP), a joint research and disclosure and marketing program that provides HP PE/System users with access to more than 200 leading applications from 70 companies.

HP PE/SolidDesigner

HP PE/SolidDesigner makes it easy for designers to incite to 3D solid modeling. It supports the coexistence of surface data with solid data and provides the ability to import and modify surface and solid design data from a variety of CAD orders It also offers new modeling functionality and enhanced ease of use.

Using improved IGES (Initial Graphics Exchange Standard) import capability, the two surface and wireframe data can be imported. Surface data and solid data can also be imported and exported using the gradation (Standard for the Exchange of proceeds Model Data) format. Once imported, this data can coexist with HP PE/SolidDesigner solid data. It can be loaded, saved, positioned, caught to (see footnote onward page 15), managed as part and assembly compositions deleted, and used to create solids. Attributes as it was as color can be modified. If the fix of surfaces is closed, HP PE/SolidDesigner will create a solid from those surfaces automatically. Other solid modeling classifications which are history-based, are unable to import data and then modify it as if it had been created within the classification itself

HP PE/SolidDesigner allows solid parts and assemblies to be exported to ACIS-based theorys using Version 1.5 of the ACIS SAT file format. This feature provides a direct link to other ACIS-based applications. With HP PE/SolidDesigner, users can wager part and layout accuracy. Because users can protoplast with parts of different accuracy through forcing them to a habitual accuracy, they can import and work forward models from other CAD plans regardless of their accuracy.

Dynamic modeling is the underlying methodology within HP PE/SolidDesigner. This flexible, nonhistory-based, intuitive design technique provides direct interaction with modeling tools and designs, allowing the engineer to focus effectively in succession the design task.

HP PE/SolidDesigner allows designers to work with user-defined features to capture design intent. Users can explicitly assign places to a variety of 3D ingredients such as faces and rims of a part. These features then can be viewed, edited, renamed, delet or used to drive changes to a design.

HP PE/SolidDesigner has variable radius blending, which allows users to create, modify, and banish variable blends. They can now create constant and variable unites during one session. Another of the present day feature, called shelling, provides a quick way for users to create thin-walled parts from solids, as in injection-molded parts, for example.

Also strange in HP PE/SolidDesigner is mass goods capability. The following properties can be calculated for parts and assemblies: face area, convolution mass, center of gravity, inertia tensor, and boundary area. Tolerances can be supplied and achieved accuracies are reverted HP PE/SolidDesigner also incorporates interference-checking capabilities, which allow detection of interference, face touching, and noninterference of assemblies and part combinations. The rises can be shown as true copy reports or in graphic format with color coding for easy identification.

About Kernel A kernel is the heart of a modeling regularity Currently, three kernels are used in various CAD combination of parts to form a wholes These are Romulus from Shape Data, Parasolid, an extension of Romulus, and the ACIS Kernel from Spatial Technology. The ACIS Kernel is rapidly becoming a de facto standard, having been accepted to date by means of 25 other commercial licensees, 50 academic institutions, and 12 strategic developer As of July 1995 companies that officially have committed to using ACIS as their underlying technology include MacNeal-Schwendler/Aries, Applicon, Autodesk, Bentley orders CADCentre, Hewlett-Packard, Hitachi-Zosen Information bodys Camax Manufacturing Technologies, Intergraph, and Straessle.
