Is it possible to dimension a spiral?

[overkill4]

Hi All,

I have a model where I'm building a composite curve with a spiral and I want to have a driven dimension which gives me the total length of the composite curve.

I know that I can measure the length of the composite curve, how can I turn that into a parameter?

Is that possible?



60% of the time, it works every time.

OK4 X dim = R or Dia - Y dim = crest to crest (ie: metric type thread pitch) - Z dim = Over all (top to bottom or side to side)dimension. Y dim can be crest to crest for 45 deg / 90 deg or whatever works for what you are doing. Remember a screw is just a incline plane rolled up.
