[Line tool: I'm stuck :- \]

Thank you, Andy!   I appreciate that.

 

[Line tool: I'm stuck :- \]

Thank you, JimW.  I now see the line contrain toggle.  And thank you, P Petondo, I've located the Attributes line style drop-down menu.  This menu has a few dozen line types (dashes, breaks, etc), but "solid line" does not appear to be one of the choices.  I cannot revert to a normal line.  Any further thoughts appreciated.

Can anyone kindly tell me how I reselt, or return to a "normal" line?  Somehow I got stuck with dashes that only go horizontal and vertical.  And I cannot reset the line tool.   Any advice appreciated....  Richard
