  • Constructed Cylinders

    I feel dumb today. I want to construct a cylinder from a number of circles that I have measured in a hole. I know this has been discussed here, but for some reason I can't get it to work. V3.2063, Mistral. Everytime I construct it, the software won't let me.

      I've tried every option, even cast & projected knowing that would create a cylinder for each circle. It'll do that, but not give me a constructed cylinder.

        I'm using Auto-circles, could it be that??

              I would extract the points and construct the cylinder from them

                  Not that big a deal. I was just trying to show that the hole was tapered and that the part mating this will slip in. It shouldn't.....

                    Pick it up as a cone, then intersect the cone with planes at the levels you want show circle dimeters for. Dimension the circle diameters and you should be there.

                        I like the cone idea if it's truly a cone. For the points method this will give you a cylinder...

                              John,

                              The bore does not look like it's taper from the measured results - more like waves or coke bottle...

                              Try constructing immediately after circle measurements and did you choose IN or OUT when constructing the cylinder?

                              Brewski sounds good maybe I'll have one for lunch...ZZZZZ
