Virtual Assembly and Design
Environment (VADE)
A Virtual Reality based engineering application which allows engineers
to plan, analyze and evaluate the assembly of mechanical systems.
This system focuses on utilizing an immersive virtual environment
tightly coupled with commercial Computer Aided Design (CAD) systems.
VADE has been designed and implemented at Washington State University
in collaboration with
NIST.
Open Assembly
Design Environment
The Open
Assembly Design Environment (OpenADE) project is an initiative at
NIST to provide an integrated and augmented CAD environment for
assembly design. The project aims to
1. identify
representations and issues for the next generation of
assembly-related standards, and
2. assist
designers with assembly considerations throughout the phases of a
product’s design-from concept to final process plan development.
OpenADE’s open
architecture provides standard interfaces that allow it to link to
commercial and noncommercial design tools such as parametric design
systems, VR environments, assembly analysis tools, and assembly
process planners. The OpenADE project has explored issues related to
knowledge representations, VR, assembly-level tolerances,
constraint-based specifications, and assembly process management.
Several components of OpenADE have already been implemented. NIST
also plans to extend OpenADE’s assembly knowledge representations
and handling of geometric and kinematic constraints. As a prototype,
three applications-VADE, Pro/Engineer, and dVMockup-have been
integrated to share geometry, assembly constraints, material, and
sequencing information. VADE, as a noncommercial design tool, plays
a key role in the sharing of geometry and assembly constraint
information with the commercial CAD systems. The VADE system has
provided a key thrust to this assembly representation
standardization effort.
