I've been looking at inspecting a selction of cylinders. I'm looking to plot the results onto solidworks 2003, but i want to put in tolerence bands so that all the deviation off the perfect cylinder are highlighted. Anyone know if there are programs that will show this up already and output cylindricity and roundness values.
Thanks Anthony
If not, it might be an interesting macro/add-in to do. What's unclear to me is how the cylinders are modeled in SW. Do you have measured points ? an imported surface or volume ? Could you send me a sample to have a look ?

Anthony have you thought about the idea of creating a solid using cloud data from your CMM, then using a "perfect" SolidWorks model either as a go-nogo (with interference detection to a "hole") OR using the "cavity" function to give you the difference between a perfect cylinder and your actual cylinder OR using SolidWorks Utilities to Compare Geometry (which will highlight differential areas)? I know these methods don't give you DEGREES of difference (out of tolerance), and if you're trying to create SPC tolerance data they probably aren't what you're looking for, but at least they can allow you to accept or reject particlular cylinders. Are you trying to do acceptance/rejection or are you trying to determine the real results of particular processes?

Such programs do exist. I saw one at the NPE recently, I believe it was called Shape-Grabber. They sell both the hardware and the software. There are others as well. You might want to look at ScanWorks from Perceptron, Direct Dimension, or Polyworks Inspector, all of which were in a recent issue ot Time-Compression Technologies magazine.
