Trying “CAD” Again …

With some decisions made about the new layout design (overall size and shape), it’s time to get down to serious planning.

First up, I decided that I’m going to give another go at using the computer for layout design. That meant choosing a CAD program of some sort that would run on the Mac. While I already have imaging and illustration software, as good as it is, it doesn’t work well for layout design. I also determined that a generic CAD application would be problematic, as I would have to “teach” it all about track before I could even think about designing a model railroad — something I just don’t have the time for.

Some time ago, I had looked into track planning software for MacOS, and found that there were basically two options. After re-installing the demo versions of each, I settled on Empire Express, from Haddon Software. While there are a couple of features I would like that are “missing” from the application (specifically, automatic yard ladders and bezier curves), I like the way the software handles most situations. I’ve included a new screen shot of the software here, since I recently discovered I boogered up the previous ones (they could only be seen on a Mac!).

As mentioned previously, some of the design criteria have already been set — benchwork height and overall layout size, for instance. Minimum radius is still up for discussion. I am waiting on a response from Victor Models in the UK regarding the suggested minimum radius for their SR&RL #19 model, and I also need to do some testing with the Bachmann Forneys (the railroad will have three of these in operation). I’m hearing and seeing conflicting information regarding their operation. Bachmann claims that the Forneys will go around a 22″ radius curve with a train in tow, and at least one reviewer has confirmed that it worked. However, we occasionally had problems on the 26″ radius curves of the MADModules/Berrett Hill specs (although there may have been other reasons for some of those problems — they weren’t so bad the last time we had the modules set up). I’m hoping that I can make the curves be 26″ radius or less.

I’m also still hoping to be able to incorporate a version of the “Keg Harbour” plan into the layout, along with 8-feet of the yard modules. However, both eat up a lot of space, and this is, at present, going to be a very small railroad. Converting those items into “modules” within Empire Express will be an “early” order of business. That will also give me some opportunity to practice some with the software and gauge its accuracy.

  1. Hi Geren, Interesting. My j-o-b is at a CAD software devel co in Columbia that makes a top-notch CAD program for the Mac. ‘Tis Vectorworks. Also, it works for stage and lighting design and is used by many entertainment designers … as a bit of a crossover into your j-o-b.

  2. Vectorworks is impressive stuff — I looked at it back when we talked about the virtual set system we installed at my j-o-b. It’s far more program than I would ever need personally. Heck, I can barely operate a pencil and paper when it comes to design. Actually, that’s an exaggeration. I’m pretty good with certain 2D design and graphics programs like Corel Draw and Photoshop, and I’ve got some knowledge of Solidworks. But, for the most part, using CAD and 3D design programs completely eludes me. For some reason, I have a hard time getting my head around it.
