I may develop a plugin for model railroads, typically at H0 scale (1:87) but it could be at other scales too. Since I not very often do SketchUp models of scale models I wonder how you are doing this and if there is any best practice.
I’m thinking it may be easiest to draw everything in as if it was scale 1:1 in SketchUp. This way users could download buildings, trees, vehicles etc from 3D Warehouse without having to resize them and the plugin wouldn’t need to draw its object differently regarding what scale the users’ physical models are in. Also I suppose face creation is easier in this scale and perhaps other features of SketchUp works better in full scale too (clipping?).
The other option would be to draw in the model railroad scale which might be easier if users want to base the layout on the physical dimensions of their home. However I think it would be fairly simple to draw the room you plan to have the model railroad in, scale it up 87 times with the scale tool and base the railroad on that. Then everything could be scaled back to model railroad scale when exported/printed.
Thoughts on this?
