Cubic elements can be skewed, rotated, translated (slid),
replicated, repeated along straight or curved paths,
and are the primary tool for most projects.

Projects in RogCAD are built up mostly through the use of cubic
primitives. The user defines a cubic shape by specifying two
diagonally opposite vertices.
RogCAD automatically supplies the remaining six vertices as well
as the connecting lines and planes.
These cubic elements can be skewed, resized, rotated, translated,
replicated and repeated along straight or curved paths.
Thus generated are things like rows of mitered boards, windows,
or rows of buildings.
Points, lines and planes can also be defined independently, and are
integrated with the cubic data structures, as are curved surfaces.
Complex curved surfaces are modeled by stretching basic circular
shapes in a variety of directions. The boat shown here required
about two hours of data entry.
More about RogCAD features
* Anything that can be modeled in the most expensive
3D CAD software can be modeled in RogCAD.
* Designs are built quickly. RogCAD has many automated
systems -- as well as transformation routines -- built into
its data text file system. A minimal amount of data entry
goes a long way.
* It's strictly keyboard entry, therefore inherently precise.
Design elements fit together seamlessly.
* Data for a project is displayed collectively in a text file,
allowing data entry and editing in any order.
* Can combine wireframe and surface modeling in any manner.
* Provides automatic surface rendering, with automatic shading
for light source direction.
* RogCAD's automatic surface rendering generates smooth
gradient lighting on curved surfaces.
* Provides customizable rotatable grids and multicolor wireframe lines.
* Provides unlimited range of perspective points and focal points,
and allows you to specify those values using 3D coordinates.
* With those precisely defined perspectives and focal points and
rotatable grids, RogCAD is excellent for doing analytical work.
* RogCAD provides smooth 3D navigation with real-time display
of perspective point and focal point.
* Can overlay multiple projects.
* Provides excellent control of the color palette.
* RogCAD's most striking aspect is its complete stability.
* RogCAD requires no installation of any sort, and it uses
just a tiny portion of your CPU and RAM. You can run
multiple copies of RogCAD simultaneously.
* You can expect to spend one to five days engaged in
self-study with the instruction document, depending on
what skill level you are aiming for.
Limitations:
* Not compatible with any other CAD format.
* You need to have an appreciation for the
"by the numbers" approach used in this software.
* Not comparable to sophisticated mechanical design software.
* Currently contains no libraries of predrawn elements, therefore
not best suited for rapid detailed drawings of standard designs.
RogCAD is best suited for accurately conveying the overall look
of an object, especially the unconventional.
History
I originally wrote RogCAD to run on my old IBM XT with the text-only monitor.
The data points had to be plotted on paper by hand and then connected with
a straightedge.
From 1993 to 2001, I developed it into its nearly current form.
Significant new features were added from 2021 to 2023, and
RogCAD is now in its final form.
For RogCAD's complete history and more information on why
I use RogCAD, click: RogCAD history
RogCAD is available for Windows, DOS and cross-platform.
RogCAD is freeware. - Roger Luebeck
I am the original rogcad. I named my CAD program rogcad in 1995,
which marked the beginning of the name. I originated the domain
rogcad.com on 6/30/2000 and have owned it ever since. There is a
rogcad listed on an online chess site, but it is not me. I haven't
played chess since 1969. Any occurrence of the name rogcad on the
Internet outside of my CAD work and my other web pages is not me.
