Designing Engine - Summary Window Nerfs Bore/Stroke

[Eric.B]

When designing an engine, you can tweak some sliders and then open the Summary window. Just click "Apply" a couple of times, and observe how the sliders for bore and stroke go down slightly every click, along with the displacement number near the bottom of the screen (the displacement slider remains stationary.)

And as a related sidequestion, is it correct that the stroke/bore sliders max out at 75, unlike all other slider that max out at 100? If you drag the 3 displacement slider to zero, and then drag bore and stroke to max, the displacement slider is only at 50, and this represents the max displacement the engine can have. (Test by draging the displacement slider from 50 to max. You will se the displacement number fall a bit as you drag up to 51 and then increase back to the earlier max when you get it up to 100.)

I think there were some talk about this on the forum in july or something, but I cannot remember how that discussion ended.

Both of the things mentioned are bugs that I had fixed previously. But they came back due to additional features added and bugs introduced by fixing them. (If memory serves me I made width/length proportional to layout which broke bore/stroke when using the summary stuff...)

I am contemplating I believe Frank's fix to the issue. (And if it' wasn't Frank's idea, sorry! I'm getting old!) By removing displacement slider all together. Making both the bore and stroke inputs to be exact. (Type in the bore and stroke you want, within the limits.) I still haven't made up my mind, we'll see how things go for 1.18...
