I am manually routing some tubing and would like to have a dimension for the length of tubes.

Path length is grayed out and smart dimension will not generate a value.

Thanks,

Andy

Mark,

I am using SW2014, the problem might be that the geometry is a fit spline with no constraints.

Get a message " A dimension could not be created from the selected items ".

Thanks,

Andy

Is the fit spline being define with an underlying spline or splines or other sketch geometry? If so you can click on the fit spline and then use the "select other" to select the underlying geometry to dimension. If the fit spline is made up of multiple pieces of geometry then you will have to dimension each of them separately and then sum them.

One fairly simple way to accomplish this is to calculate the volume of the swept tube. Assuming your cross section is constant, the length can be easily calculated.
