Using Plans

Models made in Trainz are life size (1:1) witch leads to a problem in taking measurements from scale plans, that is the thickness of the line maybe an inch or more. All the plans you will find will be on paper or were on paper witch has a 2% error. There is nothing you can do about ether but it comes out to about 2" for an 85' car and no one will see it in game.

I know of three ways to use plans and have tried all at lest one time.

Measurements

Simply use the measurements on the plans and/or use a scale rule to get the numbers to enter in.

Template

You scan the plans in and crop the scan to a know size then make a box or a plane the same size and UV map the scan onto it. You need to make a side, end, and top.

Background

Most 3D modeling programs let you add a custom background that you can re-size. This is what I use and have used in Gmax and Blender. Getting the size the same on two or more plans is very hard, one will be off just a bit. What I do is use the side as the master and if the end one is off move the part back in the side view.
