I want to make sure the finished product is smooth in the Y direction, so I made that my 2nd pass, but there are still X ridges. What settings will make sure the sloped furrows are smooth along their length?
There are only so many things you can do with a curved surface and a flat tool.
reduce step over
use an outline operation with a small step down
use a pocket operation to select the wavy area and try enabling the contour option of that operation. this is a long shot and will require a lot of parameter tweaking.
that looks like a bug. are you able to right-click export your workspace as a .kmz and email to me [ sa at grid dot space ] – from there I can replicate and investigate. thanks
I checked your settings, and precision was 0 which means it’s calculated using the animate precision from settings. And that was almost using the lowest resolution possible. This led to stepping artifacts. I set precision to 0.035 and got very good results. Alternatively, if you crank up the animation to something like 2000 or 4000 and watch the javascript console, you can see the auto calculated precision.
