I have a pipe, made out of two cylinders stuck together, one smaller than the other, and revealing itself inside the larger one. (easy way to do 2 textures) Now I'm trying to chop them up some. One I'm trying to cut in half, like a c shaped pipe- half missing. The other I'm trying to cut the top off at an angle. I tried cutting the pipes apart with a basic cube, but it kept giving me errors. I moved it about alot, and consulted the manuals. I then made a higher detail polygon count cube using the grid IPAS. lots of little polygons in that sucker, I forget how many. I tried it again, and it kept giving errors. I then proceded to make a text cylinder, with more parts to it along the length of the pipe. I tried the subtraction boolean again, and no go. Somehow I finally got a strange result (mabe on the last way I talked about, I forget)- it was the half pipe, with one single plane left from the cube. I don't understand it, so I thought I'd ask here. I know there were probably many planes made up in that grid/cube type object, but I figured at least one would get it. 🙂 I didn't know how to get a 6 sided, lots of polygons, cube to use as a subtractor. Any pointers? I realize I'm not the polygon guru here, and probably missed something really simple. (but I thought booleans would be simple, if they worked..) The pipes look great, so I'd like to cut up what I have now, instead of recreating them, if possible. Thanks as always, JNJ
