Three steps to effect the Revolve with Rail command - select Axis, then Profile, then Rail. At each step, the cursor should trigger a pre selection highlight of the candidate object, but does not. This is a feedback issue. If several objects are close to the cursor during the hover, the cursor changes from black style to white style to indicate a nearby appropriate candidate. But, which one? Pre selection highlight would indicate which one.
Most (all?) other multi step tools and commands, including those with the green checkmark to complete (Loft, Extract, Fillet, etc) produce a preacquisition highlight.
Other aspects of the Revolve with Rail process seem to be working as expected. The candidate object does highlight red when acquired with a click, and the command does create the solid object as expected.
I think the is a v2023 issue. Anyway, I cannot remember noticing in earlier versions.
