In previous versions of MicroStation (as it appears in the help files), there was once an option to "Add Threads" to a feature hole. This option seems to have been removed or depreciated in the CONNECT version.

My suggestion is to add this option back in, complete with variable inputs (thread pitch, full length threading vs. specific distance, etc.), and (if it wasn't an option before) to add the same to cylinders, custom revolved solids/pins, , etc.

Thanks!
