    Curve by equation - logic expressions?

    Hi, thanks for the suggestions. I shall have a play with the VSS when I get home; my only concern is the complexity of my curve equations - one of them includes evaluating the root of a fourth order polynomial...it's not pretty! Just been browsing...shall also see if I can use a graph - I...

    Curve by equation - logic expressions?

    Is it possible to include logic or boolean expressions in the definition of a curve? I've two different curves, one presenting an error due to atan(something/0) and the other producing a discontinuity in theta (by 180 degrees) also due to trigonometric functionality. The first error I could...

    Sweep and rotate profile along helix

    Many thanks for the input - I finally solved it this evening. For info I couldn't open the second example above, maybe it was created with WF4? Yep - I created a straight trajectory coinciding with the x & y plane intersections, then also created a helix trajectory (rotating about that x-y...

    Sweep and rotate profile along helix

    I have a sketch in the x-y plane. (in case it's relevant it's defined from two datumn curves and an outside edge). I would like to sweep it (as a cut) along a helix that propogates in the z direction (ie, in the xy plane it appears circular, centred at the origin). I have defined said helix...
