Dear sir/maam,

I have a question about using the "Coupler, thread, connecting bar" function in engineering tools.

I have been using the function Coupler "spilt bar and create coupler connection" most of the bars are separated and coupled but some of them showing the error" the catalog doesn't include articles for current diameter or selected function.

I tried to sort out this error by reading some online help but couldn't fix it. Please help me.
