If this value is too small, the trim operation may fail, since the curves on surface often do not define an exactly closed region. This value determines the distance within which polyset vertices must be in order to be merged. See Polygon Edit Vertex Merge for more information. We recommend NOT using this toggle unless you have a good reason for doing so and fully understand the implications. To help prevent accidently using rational curves or surfaces, we have removed this option from separate modeling option windows and have located it in one location in the Construction Settings window.
Rational geometry contains points which include multiple knots.
If these curves or surfaces are deformed kinks may be created. All rights reserved.
