Hello, Solidworks refugee here, with some questions on navigating FreeCAD's feature tree.

Example: I want to make this:

Step 1: Sketch on XY, draw rectangle, pad

Step 2: New sketch, draw rectangle, pad

Accidentally forget Step 3, which would have been to sketch and pad another rectangle

Step 4: New body, sketch on XZ, draw circle (or whatever), pad

Step 5: Cut 1st body minus 2nd body.

Step 6: Explode the resulting compound.

Step 7: Realize that I forgot to do Step 3.

What should I do at this point?

In Solidworks, the standard workflow would be to use the "rollback" tool to suppress the boolean operation, add the missing Step 3, then "roll forward" to reapply the boolean operation.

What is the equivalent "best practice" workflow in FreeCAD?

Wow, I've been using FreeCAD for ages now, and somehow neglected to ever learn about this! Thank you
