ParticipantThe information for importing a Table of Offsets is provided on pages 32 – 34 of the manual.
I had to fiddle with this for several days until I could understand what some of the terms meant and which features to activate and which to leave turned off. During the next revision of the manual, I would like to see a labeled diagram or two explaining the meaning of each of the terms used in this section for the benefit of us nonprofessionals.
- “Stations” and “waterlines” are pretty straightforward
- While “deckline” would seem to be fairly clear, the example shows the deckline intersections to be above those for the “contour line”, which I assumed was intended to represent the sheer or rail of the hull, so I never used this data.
- The “forward contour” is the line describing the stem in the profile view and the “aft contour” is the line describing the stern in profile.
- No example is given to show what a “flat bottom” means. Does it mean a horizontal bottom, or a plane surface curved fore and aft?
- One thing that I found out the hard way is that every space in the table must have a number in it. If there is no station/waterline intersection in your table, then you must enter a “0.000”. If you don’t do this, very strange things happen!
- I found that importing the main part of your table into a spreadsheet makes filling out the required format for DS easy. Then export the spreadsheet as a tab-delimited text file.
Hope this helps
Terry
