Maybe it's just me but I found it easier to click "merge" or "replace" when importing additional cad models. At some point a few years ago, the wording was changed and the user now has to read the question then answer "yes" or "no."
Question: Do you want to merge?
< Yes > = No
<No> = Replace
<Merge> = Merge
<Replace> = Replace
I like the old way. Who's with me on this one?
