I am working on a long term project to create a "g-scale" Chicago El train. I have received drawings of a 5000 series car, imported them into Adobe Illustrator, and begun to trace over the top and create dimensions for 1/32. The process I went through was to draw a 45MM rectangle reflecting the track gauge, placed that between the wheels, scale the drawing for a best fit, and then draw lines and measure in MM through illustrator. You can see where I started and where I ended below. After doing this I have a few questions from anyone that has taken the same approach:
1) Is starting with track gauge and "eye-ing" the location of the wheels appropriate?
2) I am scaling to 1/32 since the Elevated Trains are Standard gauge... that said I recognize it might be best to use motor blocks from USA Trains (NW2?) or LGB which might challenge my current scale. How does one come up with the right scale? There are a few measurements in the plans that I could have anchored on like wheel size of 28"
3) Where are modelers more precise vs. let things just fit? As I started the process I thought gauge was most important but as I have continued I am wondering if I should have tried to anchor off wheel size since I will probably use pre-built motor blocks. My current plans have 2.45" between wheel centers; the NW2 trucks appear to be about 3". Wonder if I should redraw with those dimensions?
4) Are there motor blocks you might recommend I should use?

Appreciate any help, this is a fun process but I am trying to figure out the right way forward.

My real job is freelance design, mostly packaging. I use illustrator daily. It's by far the best vector drawing program. Personally, I would size to the overall car length. Can't speak to the motor blocks. I 3D print mine. What are you building with? Styrene? Brass?
Thanks, good to know it is the right software. The cost is relatively high for a casual user and I am not a fan that Adobe has gone all in on the subscription model. Using the 7 day free version for now and hope to get plans done before it runs out.

Not sure how I am going to build it yet. I dream of doing it in brass but I need to investigate how I can appropriately get the bends I would like. I am very much an amateur at this and one of the goals of this model is to improve my skills.

Take a look at the Hartland ones, which are in quite a few models so you should be able to find some.

And note that our wheels have larger flanges. If you use scale wheels (e.g. 28" over the treads,) then the oversize flanges may cause clearance problems with bodywork, etc. It might be better to use slightly undersize wheels so the overall outside diameter over the flange is the same as the scale size.
Will do, thank you for the assistance again! Will do on the flange sizes
