Re: Need Help Making Part from Spec

I have made this 2 different ways for reference (and no, not in Inventor but in Solidworks).

I'm guessing you made yours the first way I did and that's why you should have 3 sections actually - 2 seams.

Dome one (on left below) uses actual sketch components and tangent relations between them but indeed has 2 seams.

BTW, check your add up on the print of the .885+9.125 = R10.010 (not R10.011).
Or if those are ALL correct, I refer to dome 2.

Dome 2 (on right below) was made using only the origin as the bottom center of the part and using only the dimensions 9.125 and 11.685.

BTW, the green lines are what I actually sketched in and then revolved both of these.

Of course thinking about this more, there is one more possibility. The 1.828 dimension could be the base of the part (straight extrude up) and then a dome could be on top of that with a width of 9.125 and a height of 9.857 (11.685-1.828). Isn't it great to get drawings supplied to you with so many questions involved?? LOL Try accomplishing work in "the real world" under conditions like this, and oh btw throw in already unreachable deadlines while you are at it.
It's fun.. Trust me. I do this every day.

Ah, touche'.
LOL I'm guessing he was told it was one, cause that is an awfully weird extruded shape we have here if it's a plate or another type of extruded object.
