I’m looking for a quick and easy way to measure the radius int the corners of a bent pipe model.  Note this is an IGES model of a pipe supplied by a customer, not a pipe routing model in SolidWorks.  We recieve the pipe models as simple 3D IGESs without any supporting data.  The corner bend radii are all supposed to be the same along the length of the pipe, but this is not always the case and we need to interogate the model to make sure.

Is there a really simple way to find out the radius of the corner in the centreline of the pipe?  We can manually build a 3D sketch along the centre of the pipe and measure that no problem, however I wondered if there was an easier way.

Using the 'measure' tool doens't appear to be much help, there is no edge to select...only the outside face of the pipe.

Thanks.
