Can you use a 'Law' within a sketch?
Can you use a 'Law' within a sketch?
(OP)
I want to offset a curve within a sketch based on a 'Law'. This will give me a variable offset results. I believe this how I created the control curves for spring-back tooling sufaces in V4, it's been a long time though. I haven't found a way to use a defined 'Law' in a sketch for offset curves. Before I write a enhancement request, I wanted to ask first; Is it possible?

In the right column (Members of Law) double pick evaluate. Inside the brackets pick the Fog law you created. The fog law is located under the design table tab.
You might need KWA for the laws you want to create. Send an example.

But you can create your curve ouside then sketch then project it in the sketch.

Note: you have to identify several 'sections' in adaptive sweep for it to maintain a reasonable accuracy.

I'd suggest you follow Eric's advice, and don't use a sketch.
Start with a plane (the same plane you'd use to make the sketch). Intersect the surface with the plane to get the reference curve. Use Parallel Curve to offset the reference curve based on your Law. And use this Parallel curve to make your multi-section surface.

Earlier this year I wrote about Laws and their application here. Try looking in these two: thread560-176891: mirror on a curve?? and thread560-191644: Law and Sweep: Corrugated Flexible Hose
I'm sure there's no need to use Adaptive sweep for what's described, or to try and do it Sketch: it's all there. As Jack says, use the, misleadingly named, Parallel Curve - controlled by the Law.
RE: Can you use a 'Law' within a sketch?
I do not think your way will work as the outside curve (intersection) will not follow the adaptive sweep.
you might have to decompose your construction and offset surfaces not using adaptive sweep.
