[Therion] Extended profile problems

[Bill Gee]

Hi Martin -

Thanks!  This is much better, but still not what I want.  I don't want the profile to fold back on itself at all.  I want one continuous profile extending from OC5a on the left to G14 on the right.  Is that possible?

If I draw them as "projection none", then two questions come up.  First, if I put survey stations in the scrap will they be used to scale the drawing?  Second, can two (or more) such scraps be joined?
