making all line segmentsof same line type show as one line segment

Can someone help me with the cmd name that makes all line segments of the same line type show as one line segment? different than PE or Join. Thanks in advance.

Two options that spring to mind are "Group" or "Selectsimilar" !! is that what you mean

Are you speaking about the Linetype generation option in the properties dialog box of the polylines ???

Or are you talking about a pline that has a line type that resets between vertices?

If so that is an option in the "PEDIT" command: "Ltype gen" (on or off).

Wow Clem, that was fast.
I didn't actually know that was a properties option too, thanks for the tip!

Yes to both Ted & Clem, Thank you.
