Creating a variational sweep
Creating a variational sweep
(OP)
I would like to sweep/rotate a single line about a circle, similar to a revolved sweep, only I want to vary the angle of the single line as I sweep around the circle, thus creating a variational sweep. I also want to control this angle with a law curve so that I can specify the angle at certain degree points and have a smooth transition between points. The start angle and end angle will be the same. With the variational sweep, I can not find anywhere to allow a dimension to be varied by a law curve.
Can this be done easily.
Thanks

Anyway, give it a look and see what you think.

RE: Creating a variational sweep
Those 2 techniques are exactly what I was looking for. I was able to acomplish the variable surface using the variational sweep and specifying extra sections, however, I found this tool can be tempermental. Using your method with Angular Law based on Sketch is very similar to how I would have created the surface in ProE, except in ProE, the Sketch does not exist in the model, but instead is an item in the part navigator. Anyhow, same result.
I have another question regarding your model and please forgive me if it is a simple question. The sketch you have to drive the angle is mainly composed of a spline. The spline is made up of a total of 5 points (start end and 3 internal). How did you create this spline so that the ends are always tangent to the horizontal line and why did you select a degree of 5. Every time I create a spline inside a sketch and make the ends tangent with other curves, I cannot make the ends remain tangent during modification of the geometry.
Thanks

RE: Creating a variational sweep
Until now I always thought Studio Splines inside the Sketcher were quite limited and non-associative and could not understand why the feature behaved differently to outside Sketcher tool. That helps alot.
Thats John.
As always, you come up with the goods.
