Blender units discussion

As usual, like a lot of things, this turned out to be a simple and profound solution.
This really helps with difficult edits in Blender. Draftsight is so much more precise.

By simply changing SCALE under IMPERIAL in Blender to 0.0254 I'm able to cross platform between Blender and Draftsight.

I was having an issue editing the roadway to be one continuous span from anchorage to anchorage, but this technique solved it pretty quickly.

(addendum. Apparently it makes no difference. I'm having a hard time wrapping my mind around this. Perhaps it has been a long day and my brain is not functioning in an optimum way.... Whatever. As Scarlett says, I will think about it tomorrow.)

I figured getting the rolling stock accurately placed would be enough for one day.

Railroad Track Dimensions

The dimensions of a railroad track are not hard to find. Railroad track rails are 6 5/8" tall, the top flange is 2 and 22/32" and the bottom flange is 5 and ?? inches. If you are picturing the capital letter ' I ' in your mind, you are on the right track. The upper portion of the rail is only 5/8 inches thick. Now the track width in the United States and Europe is 4' 8 1/2", or 1.435 meters.

Standard gauge in North America is 4' 8 1/2", measured between the inside edges of the rails.

Some Stats

The full width of the bridge floor is 85' according to "The Great East River Bridge"-the Brooklyn Museum.

The road is 2 degrees from the anchorage to the middle span.
