Friends I have a 1:200 scale aircraft .stl file and want to print in in 1:285 scale. What reduction should I use? TY Chris |

Well, if you scaled it up x200, it would be real world size, and then if you divided that by 285 you'd get your 1:285 model.
So that's really 200 divided by 285 which is 0.702 rounding up. Or 70.2 percent the size of the stl you have. |

Math is not my strong point. I was wondering if there is someplace I could find a chart for conversions on the web? |

I use this chart a lot when converting stls to other scales.

No worries. I've been designing 3d stuff for about a year now, so have to make these calculations all the time. You won't go too far wrong if you go from "scale 1:X" up to "Real world size", and then back down to "scale 1:Y". You can go straight from scale x to y, but its easier to make mistakes doing that.
So far I haven't ended up with a miss-scaled item, but it's easily done. |

Here is an online scaling calculator, with various ways to make the calculations: link Robert |
