How to end the bow of the ship

[Hrvoje-]

Please, can somebody show me how to end the bow of the ship?

I attached the Fusion file of my project.

Thank you a lot!

I stoped here.

This will work with connected profiles and rails and is best done in the Patch workspace.

The profiles need to be at least tangent continuous and also precisely touch the rails.

You will need to eliminate the very small straight sections at the bottom of your profiles and connect the end of these profiles directly to the keel rail. If you need a small flat area at the bottom, then trim it of later.

You already have a keel rail.

Now you'll also need a gunwale rail.

Your Razma Sketch would be a top view of that Rail.

So, create a new sketch on the top plane and make sure 3D sketch is checked in the sketch palette.

Elect Sketch->Project/Include->Include 3d Geometry and project the end points of the profiles into that sketch. Then connect these points with a spline.

You'll see that in the top view it will almost precisely match the Razma sketch, so no adjustments are necessary.

Then you can create the loft. Mirror, stitch patch, stitch and you;'ll end up with a nice shape.

After I modified your file there are now a few yellow sketches in the file, but  you hopefully can see the general workflow.

I congratulate you on not using too many spline control points. That's how it's done!

Peter, thank you a lot for your time.

I did not succeed to solve the problem. I could not to do one of the recommended advices: "Then you can create the loft."  I stuck up here. I have to find the error in my sketches.

As @TrippyLighting already said, working in Patch workspace makes it easier.

I tried it this way.

Offset plane 20 mm for the keel bar.
Project the keel bar to this plane
New plane for the deck using 3 points
Drawing outline spline of the bow
Lofting keel bar
Lofting side surface
Lofting center surface
Lofting deck surface
Stitching all together
Patch rear surface
Stitching it to the rest.

Thank you Michael, I appreciate the help obtained from you and Peter.

Don't loft this in pieces. This can be done with a single loft. I'll create a screencast later.

Hi, Peter! I tryed your solution it works fine. Thank you very much!

Screencast would be welcommed.

Hi, Peter!
Do you have a screencast of this solution?

[TrippyLighting]

No, it failed to upload for some reason and I’ve not time to redo it. I was under the impression you had succeeded based on your last post.
