will do, thanks. YOu'll see in the zip 4 images called Picture 1 thru picture 4. They illustrate my description of the problem. I'll reprint that text on the email.Much appreciated,Bob

Hi Bob.I got it, and I'll try to see what's up over the next day or so. Dick

thanks for your email. I bet I know where I got confused. When you choose poly with coast, you get the page of line properties. I specified the box, "do not close the line"...Paraphrase...I'm at work right now. I assumed that to apply to the whole construction, but the lmw poly is still trying to close itself. The line property only applied to the coast..correct?That would make sense.Bob Bernstein

Hi Bob.Yes, the shoreline will not be closed, but the LWM masking poly will still try to close, and that gives you a poly with crossing lines.Dick
