mmm, it’s just that the LCE figure given in the DH report for my boat is “5.022” which looks about the same as the position in the drawing view for the Lateral Area location icon. But there is another location icon on the drawing view saying LCE=4252! I would have thought that LCE mark on the plans would be the longitudinal Centre of Effort mentioned in the DH, rather than the Lateral Area icon postion….
cheers, John.

I found that they did not line up but then discovered the reason; I had ‘added’ a bit aft (a minus 100mm value on x) and then tried to measure the hydro figure from the aft section on my dxf transfer …
On another note, there is a figure of long centre of effort … in a sail boat the centre of effort is normally associated with the sail area, and you position it relative to the centre of buoyancy, bt DS knows nothing about my sails, so what does the mark for LCE refer to?

[John]

I’m quite aware of the meanings of the terms … my question related to what the marks corresponded to, turns out that none of the marks on the plans corresonds to the location of the centre of buoyancy given in the hydro report, which is the value I needed to calculate where to put the ballast.

Thanks, that edge collapse worked and I got rid of all those excess lines/edges and their associated points.
If I did hit the subdivide control net function, it must have been accidentally …
Many thanks for your help.

Thanks, I tried that but nothing happens. Collapse button is highlighted but the point remains.
I’m pretty sure I didn’t perform any Split action. These unwanted points are between ever single pair of coloured control points with additional grey coloured lines joining them.
