Thanks for the explanation regarding dart points.
I have now completed the design I have been working on and exported the table of offsets so that the boat can be lofted prior to building.
When I examined the data I discovered a crucial section of information missing – The Location Buttock Points. These are particularly important for this design as there is a hull tunnel is involved at the stern.
The lack of buttock points also explains the problem I had when I first started using Delftship and tried, unsuccesfully, to import offsets that I had taken off a boat that we are restoring. I was also unable to import offsets from a drawn and faired yacht taken from your database.
Do you think it may be an idea to look at the way Delftship handles offsets? It would go a long way to making the software excellent throughout the process from conception to build, modification or restoration etc.
Or, am I missing something yet again? Quite possible!
All the best
