Hello

I want to perform a parametric study that involves flow through a pipe with a parabolic occluder. I have created a sketch with the parabola and a circle, shown on the image (left), using a spline defined by 3 points. That is the only way I could find. However when I change the location of the points defining the spline, by modifying the parameters controlling dimensions, the shape of the curve changes back into a spline (image right), as if there were additional points on it.

Does anyone have a clue how to draw a parabola in DesignModeler or how to overcome this shape changing problem?

I know that if I go to Modify -> Spline Edit and refit the spline it works fine, but I would like to do it automatically from the Workbench level. Any ideas how to do it?

Thank you
Krzysztof
