Delftship Fairing Question

I'm simply stumped on this one.. Have been playing around with this design for three hours trying to fair one curve.. No luck. There is a lack of fairness on a surface that is contained by four crease edges yet it is not fair?

Any thoughts.. Attached is a photo. IN the red box is the unfaired area I refer.

Cheers..

 

Could you attach the other views... including the meshes... or better yet, attach the file itself.

 

File Attached..

Here is a copy of the file..

Trying to come up with developable surfaces in conical sections.. I used a cylinder as basis and went from there..

 

Here's the photo of the cylinder starting point..

 

But that one area on the sheer is driving me nuts..

 

I need the Delftship file... the .fbm

 

I thought I sent it.. It's actually Freeship... Here it is again..

 

Steve.. Thanks for taking a look..

 

What version of Freeship is this?

 

Never mind... downloaded the latest and it opened. I think I found your problem. You have a Corner connecting to a curve... here is a picture.



You can see on the left side that the corner is causing the problems trying to translate and meet the smooth curve. You have a straight line going from the corner forward and back, but the next line below it is a smooth curve... it can't reconcile the two without distorting.

 

If you right click a view and select mode/developablility check it will show you in red where the model is having problems being developable. However... this program's algorithms are for steel plate so there is a bit of leeway if the boat is being designed for plywood construction.

 

Thanks and a few updates

Hey Steve.. Thanks very much! Here's where the design is now.. I've tried for developable surfaces although most curves surfaces are red. I've tried to keep the plate errors as low as possible however I'm not sure what error translates to developable plywood.. Here are the error number.. What do you think for 4 mm plywood (skin of frame) - not stitch and glue.
