This page focuses on the Product
Management aspects of the CIMLINC period.
CIMCAD3D was CIMLINC's first 3D CAD program. It
seamlessly provided wireframe, surfaces and solid modeling at a time when
most systems forced you to move from one program to another.
CIMCAD3D had an innovative 2D -> 3D user interface that simplified 3D
modeling. It was the first CAD program to use Object Oriented
approaches, requiring original computational algorithms.
CIMCAD3D allowed CIMLINC to win key accounts such as Boeing, and several
automotive company vendors.
Catapult CIMLINC to the lead in the market for 3D CAD
systems with the first truly usable 3D CAD program for traditional CAD and
Provide an extensible platform for future 3D systems, such
as Assembly Modeler, Manufacturing (CAM), Analysis (CAI).
Provide a smooth upgrade path for existing CIMLINC customers
using CIMCAD (2D) systems.
CIMCAD3D was widely accepted by current and new CIMLINC
customers, it paid for the development costs in 9 months.
CIMCAD3D provided the platform for future CIMLINC
products, such as an NC module.
The product was delivered on time and was reliable enough
to be put into production at Boeing within months of its introduction
(rare at the time).

|This was one of my most satisfying jobs, the team was clearly
ahead of its time|
and I learned so much from them.

This followed CIMCAD's UI metaphors which were ahead of the field by
4 years. In 1982, CIMLINC showed at Autofact Unix workstation
implementing Windows, Pop Ups, Icons and Stroke recognition all networked
via Ethernet. Some of that technology is still not available today in
CIMCAD3D took the successful parts of CIMCAD and implemented them in
3D. I designed a Working Plane metaphor and developed the Snap-to-Object
feature which allowed the user to work in either a 2D projected mode
similar to what they knew or full 3D mode.
The User Interface also had sophisticated Selection capabilities
which provided the User with graphical ways to handle the complex CAD
drawings generated in Mechanical Design.
Cover for CIMLINC
using CIMCAD3D, 1986. This was actually done with the prototype software
I was developing, prior to the release of CIMCAD3D. It provided valuable
press coverage for CIMLINC. I learned the importance of managing the
Press. The cover is actually a wireframe image of a boolean operation
done on 4 Solid Model Objects. Eric Mueller wrote the Solid Modeler.
Items taken from it:
|Graphical User Interface with Programmable |
|Working Planes allowing easy 2D to 3D transition
|Object Oriented Database |
|3D NURB Surfaces |
|SOLID Models with Boolean Operations |
|Running on both SUN and CIMLINC workstations. |
