How to create Locus for Connecting rod? UG Nx7.5
(OP)
Is there any way to genertae automatic locus for connrcting rod when Crankshaft rotated.
Need a asociative profile because con rod dimensions need to vary for different bore..

I looked for some references with respect to 'locus' and crankshaft/connecting rod motion, and found this item:

Found couple of options.
One in Assembly sequencing where we have option for Motion enevlope after creating a sequence.It will create a light weight body [shaded]
One more is using Motion simulation and trace the path - issue here is either we have to go by a solid body trace that takes bit time and create lot of solid body or we can go to a curve selection which wont give a single path
but neither of this gives what i need,as this makes going out of UG modeling,thats to create a envelope when crankshaft moved.We need this envelope so that to decide clearence fro crank case.
components affect the clearence envelopes are Cranckshaft counterweight and Conr rod big ends.
the reason i need this in Modeling is because we have to try different configurations ..so it will be easier to get clearence envelope

what i thought was instead of simulation tools whether we can create some curves or sketches in modeling itself.

I looked at Johns link to the "homepages.htm"
In the description it states that the piston motion is symetrical, but it should be noted that, in some engines the gudgeon pin is not located in the centre of the piston, but instead may be slightly in from or behind centre. This affects how the engine makes its power, and also makes this motion NOT symetrical.
