Right click on the item that is crafting to cancel the item form crafting.
ROTATE:
You create this in your ThirdPersonCharacter - Pic provided - Change the “R button”, to whatever you want.
Then in PlayerBuildingSystem, Blueprints, BuildType, then open BuildPartData you can edit the option to give them rotation.
Not sure if this is what your asking as I don’t have the same problem. but this is how to setup rotation. I’ve setup the Chair to do it with no problems.
