    How to create a 2d geometry in inventor for Algor

    Anyone know how to create a 2d geometry in inventor for Algor for and axisymmetric analysis? I have imported 3d models with not problems for standard analysis.... In inventor I have created a sketch on the yx plane then bounded the path for a surface... but when you import it..... Algor thinks...

    Algor and threads

    well, a quick hand calc 17500lbf/.441in^2(3/4" dia) = ~39.6 ksi, with algor, with a b.c on the very bottom face perp to the axis, 41 ksi Von Mises stress..... Ok all is good... but once I change the B.C to fix the OD where the threads are and you get around 80.5 ksi.... so that is why I was...

    5&3/16" -16UN thread

    thanks for all the input.... yes this thread is a custom "special thread" the we had 2 parts from the 50's but no drawings for them..... So I started measureing the major of the external and using in the machinery's handbook and interpolating the tolerances from a 5", 5&1/8", 5&1/4" came up with...

    5&3/16" -16UN thread

    Anyone can help out? looking got the major, Pitch and minor for an external & internal thread tolerance. Machine handbook only covers 5 1/8 and 5 1/4. this 5 3/16"is an old odd ball thread.

    ASTM material spec for PTFE v-ring packing

    Help, New to the valve industry and I am creating a drawing for a packing set. All I Know is the current material used is a white native PTFE. I would like to ad an ASTM material spec to the print to ensure the right stuff. Thanks
