IBM Cadam Announcements

By CBR Staff Writer

Cadam adds Version 3.1 of its Interactive Design Professional Cadam

Professional Cadam Interactive Design Version 3 is the workstation implementation of Cadam’s 2.5-Dimensional design system. Geometry from one orthographic view can be projected into another view, and geometry from two views can be projected into a third view to form an isometric or true view. The package supports a wide range of dimensioning types and tolerancing styles including symbols for Geometric Tolerancing. A bi-directional data transfer capability enables customers to exchange drawings and models, and Interactive Design is closely coupled with Cadam’s geometric modeling package, Professional Cadam Interactive Solids Design. Version 3 is available June 29.

Cadam Interactive Design Version 3 Release 2

Interactive Design Version 3 Release 2 is an enhanced version of Interactive Design Version 3 Release 1. It offers a multiport window manager and optional display of side bar function key switches. Like Design Version 3, geometry from one orthographic view can be projected into another view, and geometry from two views can be projected into a third to form an isometric or true view. A bi-directional data transfer capability enables the exchange of drawings and models with host Cadam. Functions include analysis of section properties; user profile definitions, model size, and data transfer compatibility; new visualisation aids including sidebar function keys; transparent file storage; and the ability to integrate the product with advanced engineering models from Professional Cadam Interactive Solids Design and Professional Cadam 3D Surface Design. Version 3 Release 2 is to be made available sometime during December 1990.

Cadam 3D Surface Design Version 3 Release 1

3D Surface Design Version 3 Release 1 provides geometric modelling tools that enable engineers and designers to create, modify, and analyse designs involving three-dimensional wireframe and surface geometry. The techniques for defining and modifying these surfaces include trimming, offsetting, blending, and filleting. The construction techniques associated with the 3D wireframe entities include offsetting, joining, splitting, relimiting, and extrapolating. Underlying mathematical formulation and resulting entities are based upon non-uniform rational B-splines, an emerging standard in the computer aided design and manufacturing industries. Professional Cadam 3D Surface Design provides a user interface which is a three-dimensional extension to the Professional Cadam Interactive Design. It includes off-plane construction techniques, multiple co-ordinate systems, and several simultaneous and independent geometric viewports. Surface Design is fully integrated with Professional Cadam Interactive Design, the program for 2.5 dimensional design and drafting. It generates views for producing annotated engineering drawings, and allows 2.5 dimensional geometry from existing models to be generated into three-dimensional geometry, for three-dimensional modeling. 3D Surface Design Version 3 Release 1, which may be operated under the control of Resource Licence Manager, is available in the US from December 31, 1990.

Manufacturing System Version 3 Release 1 establishes Cadam’s framework for graphical numerical control part programming on the RS/6000 Unix machine. It is fully integrated with Professional Cadam Interactive Design, and enables users to simulate the cutter motion of their part programs. Operators may choose from several options for controlling the range of motion and display characteristics of the graphical replay. These functions require Professional Cadam Machining Center. Professional Cadam Manufacturing System is a prerequisite for Machining Center applications. These applications allow users to develop, verify, and edit part programs, and IBM says this is an alternative to language-based systems. It’s out December 31, 1990.

Professional Cadam Machining Center Version 3 Release 1 Professional Cadam

Machining Center Version 3 Release 1 enables n

umerical control part programmers and manufacturing engineers to develop part programs in a multi-axis milling environment, with up to four-axis tool control and five-axis positioning. It provides contour milling of sequential and chained boundaries, pocket milling with island avoidance, and auxiliary-function command programming. With its prerequisite, Professional Cadam Manufacturing System, Professional Cadam Machining Center provides cutter path optimization and precise simulation of machining operations. The Machining Center is integrated with Interactive Design, so as to enable the user to access a common geometric database, and perform common geometric construction and editing functions. It provides a user interface that creates pop-up panels and windows to streamline data entry. Version 3 Release 1 may be operated under the control of IBM Resource Licence Manager and is available from December 31, 1990 in the US.

Solids Design Release 2 3D-Capacity

The Interactive Solids Design Version 3 Release 2 product is said to offer a high level of integration with the new Three Dimensional Surface Design product. The three-dimensional wireframe construction and editing is identical between the two products, and wireframes developed in either package may be transferred to the other. Surfaces or faces that make up a solid model may be transferred to the Professional Cadam 3D Surface Design product. Once these surfaces are brought into the three dimensional Surface Design, they may be manipulated, placed in archive, or passed on for input to manufacturing departments. Physical plastic prototypes can be generated directly from the solids geometry via a push-button interface to stereolithography machines which allows users to build prototypes of models. Like Release 1, Release 2 enables engineers to create three-dimensional solid models that may be used to generate hidden line removed views and shaded renderings. Clearances and interferences between objects in an assembly may be determined, and the user can produce the required views of the solid model for engineering documentation, including orthographic, isometric, exploded, and hidden line removed. Release 2, which may be operated under the control of Resource Licence Manager, is available December 31, 1990.
