Whats the name of this of shape? and whats the efficient way to create them

[Carlos Medina]

I use this shape a lot, to make buildings, entrances, chests etc… (i don’t even know the name of it)
I usually make them by combining cylinder and a square.
i hate repeating the process every time i need it, and i haven’t found a way to easily create it with primitive shapes.

Is there a easier way to create them?
being able to edit the rotation segments would be more than ideal

I don’t have a name for it, but I’d use an extruded rounded rectangle for it:

you can always use the File/Save Object Preset… in the Object Manager to save anything you make for later use (use Load Object Preset to get it back). You are using the Slice tab in the Cylinder?
