Michael, This may be a bug too:

When I go to run flow on the wheel object, using the circle with the straight line as the base and the circle with the spiral line as the target -
All objects on the screen disappears when you run the Flow command.

Look at the two files: spiral_twist_ex02_1stBeta.3dm and spiral_twist_ex02_2stBeta.3dm files were made in the respective app versions.

You have to try to flow the wheel object in the new Beta to test it.




In the last beta, the flow works fine.

Note: that the above picture is from the first beta, where Flow worked. (it did NOT work in the new beta, everything vanished) The spike on the flowed object is just a product of the objects being flowed in the degenerate area, but not the bug I'm talking about.
