Mr. Bodo Hasubek 3 Report post Posted November 12, 2017 Dear all, I would like do have a defined accuracy for my imagecurves and offsetcurves.I found two settings that may influence that: 1) .setNumberOfEvaluationsForParametrization()2) .setApproximationTolerance() (both apparently work for imagecurves and offsetcurves) Questions: i) What exactly do they do and what is the interaction/dependence between these two parameters?ii) Which one should be used?iii) What are the standard values for those parameters? (I couldn't find the corresponding get... functions) Thank you and kind regards,Bodo 1 Share this post Link to post Share on other sites
Mr. Carsten Fuetterer 9 Report post Posted November 13, 2017 Hi Bodo, an image curve will be default be the exact curve as the source curve. When you change the parametrization to e.g. "Unit Speed", then the curve will be approximated with new control points to fit the original curve within a certain approximation tolerance. The command .setNumberOfEvaluationForParametrization() is not used anymore and should not have any effect on the curve. The default value of the approximation tolerance is 1e-5 best regards Carsten 1 Share this post Link to post Share on other sites
Mr. Bodo Hasubek 3 Report post Posted November 14, 2017 Hi Carsten, That's what I needed to known. The parametrization aspect is really interesting. I didn't expect that, but it makes sense. Thank you,Bodo Share this post Link to post Share on other sites
