When you are changing the dimensions, they are all locked to scale, so changing one with keep the others in proportion. Will it mess up the build if you like only change one dimension?
The problem I'm having is that I finished my first helmet, which I scaled at a height/width/depth of 280/214/335 mm, since I measured the proportions to my head and 28 cm left a good amount of space extra. So I built it and then when it was finished, I found that, while in terms of height and depth there was plenty of comfortable space inside, it wasn't really wide enough and it was like scratching my head and all that (to wear it, I had to like really trim off parts in the inside and pad it). So I'm planning on starting a second, better helmet this time but I'm not sure what to do with the scaling. Like I said, the height and depth of before was fine, the width is the problem (since apparently I have a very wide head), but then another problem came because when I make the width larger - I tried 228 mm width - the height and depth then also get even larger, and the big parts don't even fit on one page so... yeah, not sure what to do.
Thanks.
