hi everyone would really love if somebody could show me how to tackle this project. the other day and niece had a project where I thought I’d be able to assist and would be no trouble loading this project on my CNC machine. But to be honest, I couldn’t get past the design so the project never went much further. my niece needed a project done for her school and we were going to shape a hand surfing plane( please see photos attached). I was quite embarrassed as it brought me to an abrupt hult on how to tackle this design as simple as the object looks. It has a three-way curve system and I really struggled to create the object in Shapr3D so I could start some G codes for the CNC machine. Would love any suggestions if anyone’s out there to help.
You could use loft to make it work but just simple extrude and shape with fillet can do it.
- Make the curved board.
- Extrude a rough shape of the lip.
- Fillet
It’s kinda similar to this process for an AC knob.
Extrude two profiles. Intersect them. Add filets. Serve on a table.

Sorry, didn’t noticed the center part 
As a variant project a line in the center and use move tool on it
Or simple extrusion and filets will work too, as @SCALEMODEL mention.
This one is using loft
That’s awesome guys. Thank you so much. Just one thing that that image doesn’t show not only this round and it curves one way. It also curves a third way which archers kind of like a surfboard. It’s the third arch I’m having issues with.
So what would one add this shape to the final shape or create it all in one? I never thought of doing that so-called Finn like this ,that makes good sense to create two separate shapes and morph them.
You should be able to union the 2 bodies.
Here’s how I created this project. Three sketches, one revolve and two extrudes. Finished with fillet radii after the subtract and union.
The middle lip is covered very well, so I will cover the 3rd way it bends. Hard to tell from the photo how the front/back curves up or down like a surfboard but either way this will work.
Try all around loft.
Hey @SCALEMODEL
Can you explain your solution to me better?
I find this very interesting for my future work with the organic shape?
For example, for a seat for a chair.

Thats a good point that does look like a chair seat. I’ll put together more detailed explanation.
Google it. Shows both sides and hand straps. Odd shaped thing.
Interesting result can be achieved 
Yup above is basically it.
Only thing to add.
- Middle all needs to meet and be tangent.
- You control the shape of the oval by introducing more smaller or bigger Fans that you use to LOFT.
Awesome tiger Mike I would never thought of doing it like that.
