RogCAD, for DOS and Windows operating systems
3D CAD modeling Keyboard data entry CAD software from yesteryear, for technically oriented users. For hobby or productivity. This software, typical of simplistic 80's CADware, does not provide photo-realism or fast modeling routines, but it does provide complete control over the output, being keyboard entry based. It's especially useful for combining wireframe modeling with surface modeling in a customized manner. Also, being keyboard entry based, it allows for easy editing of designs. One simply edits a text file containing the data elements, using Notepad or any text editor. RogCAD is a general use CAD program. You can request a copy of it or hire me to model your project for you.

It's a proposed awning / possible screenporch for a client's cabin. Here's another recent project for a house addition - New workshop/office. FREEWARE: If you would just like a copy of RogCAD, drop me a line. (But first take a look at the How To document, which is a brief introduction to using RogCAD, then the instruction document for the DOS version.) RogCAD is available in 640 X 480 for DOS (15 colors per palette), and 1024 X 768, 1280 X 960, 1400 X 1050, and 1600 X 1200 for Windows (255 colors per palette). Here's the Windows 1024 x 768 interface: gear cineplex |

More about RogCAD features:
* 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 shading for light source direction.
* Provides customizable grids and multicolor wireframe lines.
* Provides unlimited range of perspective points and
focal points, and allows you to specify these values
using 3D coordinates.
* Can overlay multiple projects.
* Provides excellent control of the color palette.
Limitations:
* Not compatible with any other CAD format.
* Slow learning curve. You need to have an
appreciation for the old fashioned "nuts and bolts"
approach used in this software.
* Contains no libraries of predrawn elements,
therefore not best suited for detailed
drawings of standard designs. Best suited
for accurately conveying the overall look of
an object, especially the unconventional.
* Surface modeling of curved surfaces is not
fully automatic and requires a lot from the user.
* Surface modeling of complex objects needs to
be done in multiple operations.
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 current form.

Special Relativity explained in absolute terms - eliminates the twin paradox, shows Einstein's clock sychronization diagrammed in absolute terms, and ends all confusion regarding relative frames of reference. Completely compatible with, and in fact subsumes, Einstein's relativity. Not Lorentzian relativity. Reveals what is transpiring behind the scenes of Einstein's treatment. Documents: Relativity in Absolute Terms. My most comprehensive online document. A concise overview of why special relativity must be diagrammed in absolute terms. Twin Paradox Animation on youtube. More concise text than found in the document below. Twin Paradox Animation. Expanded text, and animation of the twin paradox. (Embedded youtube animation.) Twin Paradox Explained. A similar discussion of the failure of spacetime diagrams. Twin Paradox Animation. Alternative text, and animation of the twin paradox. (Embedded youtube animation.) Absolute Frame of Reference Absolute frame of reference in the physics community. Free pdf file of the book: Relativity Trail, free pdf format, with 192 pages, 65 diagrams and 75 illustrations, will provide you with complete detailed algebraic derivations of all the kinematical effects of special relativity. Everything is charted out in absolute terms against a system at rest with respect to the totality of the universe for perfect clarity as well as soundness of theoretical basis. It is the totality of the universe that imparts the inertial properties of clock rates and lengths which generate the effects of relativity. This is explained in detail in Relativity Trail. Excerpts from the book Relativity Trail with included images. Einstein explained in excerpts from Relativity Trail.
