driftworks

I'm not finding the commands, settings or icons referred to in several of these solutions... perhaps I should clarify my system set-up... I am working in VW 9.5.3 within Mac OSX 10.2.4. Should have included that in the original post.

I am coming out of the dark ages and drawing a project completely in 3-D... somehow my walls have become "sticky"... when I draw a new wall with the wall tool, an existing wall becomes hightlighted upon the first placement click, and when I enter the second click for the end of the new wall, it instantly extends and fillets with the wall that became highlighted on the first click. Very frustrating. Thoughts appreciated.
