Besides myself, an electronic design engineer,  three of our modelers are also talented electronic technicians.  This gives PMD a BIG advantage over most all the other model building companies out there.  When it comes to the wiring and animation part of the construction, you will quickly see the difference.  With the  complete resources of CIRCUITRON, Inc. at our disposal, virtually any kind of control and signaling systems can be implemented.  If we don't already stock the circuitry necessary, we can custom-build it.  You will be amazed at the results!  As you check with other model-building firms, you will soon realize that most of them avoid electronics entirely (because they are not comfortable with it!) or utilize very simple circuitry to implement only rudimentary control and signals.  The level of detail provided by this approach is very limited, and this is one area where I am not afraid to get up and "toot our own horn".  You will find that a PMD constructed layout will have all color coded wiring, neatly bundled and ty-wrapped per electronic control industry standards.  A complete wire run list and schematic diagrams of all custom electronics will be provided at completion.

Please do not be misled by some of the wild claims you may read about Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM).  The operative word here is Aided.  CAD is just a tool, in many ways not significantly different from the draftsman's table, scales and drafting equipment.  It is, without a doubt, more precise than the best draftsman out there.  It is not necessarily as quick.  And, no amount of precision will make up for sloppy technique or lack of insight.  Designing model railroad layouts is far more art than technical skill, and the CAD system does little to improve the operator's artistic ability or actual design capabilities.

With all that said, we do use Computer Aided Design for virtually all our projects.  The biggest advantage it provides is the ability to quickly make changes to a completed set of plans without having to re-draw everything.  For that reason, I wouldn't give it up for anything.  We have six computer systems in operation here at Circuitron / PMD.  We run our CAD software (we may use 3 distinct systems for different parts of the project) on a 2.66 ghz quad core Pentium class computer with gobs of memory.  A second Pentium™ machine with somewhat less power serves for those times when more than one person is designing.  We have 3 different model railroad track planning software packages installed and we also utilize AutoCad and CorelDraw for certain parts of the design process.  We have a mid-sized and large format (42") plotter as well as a 17" x 22" color printer for check plots.  We use a third, somewhat older computer to run much of our graphics generation for custom sign-making, decals, etc.  We have been a registered CorelDraw reseller since version 3 was released in 1992 and we currently use CorelDraw versions 8-13 for most of our graphics work.  Combined with our 1200 dot per inch laser printer, our 1200 dpi Color Laser printer and our 2400 dpi high resolution inkjet printer, we are capable of manufacturing custom signage, control panels and decals in black and white or color with extremely fine type in any of the hundreds of fonts Corel provides.  A fourth system is used for billing, time tracking, estimating, etc.  A fifth machine controls our Laser Engraver and the last is a venerable early generation Pentium™ machine used to control our 3 axis CNC (computer numerically controlled) milling machine and our 3 axis, 4' x 8' CNC router.  We now have the ability to design and program a part on the computer when there is no commercial equivalent available and then use the Laser and CNC equipment to machine it out of wood, plastic or plaster.  Multiple identical pieces are easy to generate this way and perfectly sized custom retaining walls, columns, bridge abutments, etc. are a snap.  The CNC router  allows easy profiling of all curved plywood sub-roadbed pieces cut to a precision of 1/100 of an inch.  The computers are networked for easy file transfer, printing and archive backup.
