[Ed...] Posted September 22, 2020 Share Posted September 22, 2020 I have made composite 2d curves by using the Read Nominals function to allow the evaluation of multiple curve features simultaneously (composite profile tolerance on drawing allows features to fit/translate but only as a group). When reading in / appending the nominals in to the composite curve, Calypso creates joining lines that connect each of the separate curves. The last point of one source curve is being automatically joined to the start point of the subsequent curve. Depending on where the start and end points are, this phantom line crosses over actual nominal data and is causing issues during the evaluation. It seems Calypso is treating the phantom line as if it is nominal data and everywhere the phantom line comes close to actual data it shows relatively massive deviations that are not real. I've attached a screenshot of a characteristic graphic that may help explain the issue. Any help is greatly appreciated, thanks! Ed Link to comment Share on other sites More sharing options...
[Cl...] Posted September 22, 2020 Share Posted September 22, 2020 Are you sure that the curve is open? Check to see if the "Open/Closed button is toggled open. See the red "squiggly line? That segment is closed. Not sure if that's the problem, but something to look at. Link to comment Share on other sites More sharing options...
[Me...] Posted September 22, 2020 Share Posted September 22, 2020 I don't know the answer to your question but here's an alternate method to evaluate multiple curves with fitting... Measure all your curves individually. Copy the curves you want grouped for a Best Fit analysis. Recall the points of each copied curve into the new curve without recalculating the nominals. You're creating an exact duplicate that's recalling the original. Use Alignment from Several Curves (Curve Best Fit) and select all your original curves you want to Best Fit. Apply the Evaluation Constraints in the alignment as needed. Change your copied curves into the Best Fit alignment and/or report their profile in the new, Best Fit alignment.

[Ed...] Posted September 22, 2020 Author Share Posted September 22, 2020 In response to Clarke, the curves are definitely open. @Robert, thank you for the suggestion, I will give this a try and update soon. Thanks Ed Link to comment Share on other sites More sharing options...
[Ed...] Posted September 24, 2020 Author Share Posted September 24, 2020 @Robert, I've implemented your solution and it appears to be working well. Thank you for your help! Ed Link to comment Share on other sites More sharing options...
