22:24 <ohsix> i have a questionnnnn, preparing pictures

22:26 <ohsix> http://i.imgur.com/U8lp3Mf.png i have this, and i want to cut into the model / have a work plane at the current camera view, i can't just draw a rectangle. i can draw in 3d but i'm geometry-dumb enough to not just do it

22:26 <ohsix> https://f4.bcbits.com/img/0007822607_36.jpg it's supposed to sort of resemble this, as 3d as reasonably possible tho

22:27 <whitequark> it doesn't make sense to have a workplane at the current camera view because the camera view is far from the model, it doesn't come through it

22:27 <whitequark> or rather the frustum encompasses the model or something like that

22:27 <ohsix> yea i know that, but the result is similar

22:27 <ohsix> right, with that projection it might as well be 'infinite'

22:28 <whitequark> yup

22:28 <whitequark> so, hm

22:28 <ohsix> i modeled it really bad / quickly to show someone something, it is just a cube with a subtracted rect on each face

22:29 <ohsix> i could put a workplane onthe inner cube but there'd be a compound angle they'd meet

22:29 <whitequark> can't you just take the three vertexes that form an equilateral triangle

22:29 <whitequark> and put a workplane on it?

22:30 <ohsix> i tried that

22:30 <ohsix> hm, i didn't try it on the inner cube though

22:30 <whitequark> oh, right, that won't do

22:30 <ohsix> the first thing i did was similar to that, drew in 3d to get a reference at bottom, front corner

22:33 <whitequark> ohsix: http://www.math.toronto.edu/mccann/assignments/199S/cutcube.pdf

22:34 <ohsix> i hadn't even thought of just looking for a geometric thing haha, i was like 'oh i could ask someone!' :D

22:34 <ohsix> i'll have to read that, i had a false start that looks similar

22:34 <ohsix> k i'm on irc on a weird computer and it's bugging me, bbl

22:34 <whitequark> it's really really simple

22:35 <whitequark> cut a few adjacent edges in half, pass two lines through that, maybe use a center of the cube for the workplane origin (or don't)

23:14 <ohsix> i've kind of been conscripted to operate the 3d printer, solvespace has been great for making test parts so i can learn about the plastic & printer properties

23:15 <ohsix> the '3d printer guys' i spoke to don't really seem to know or care about the materials and stuff that much, they're like, print and reprint until it is right; but you can know the shrinkage and shit of the material you use most of the time :D

23:16 <whitequark> bleh
