Shape3Dx tutorial and discussion

[magentawave]

Okay man, I started at the beginning of this thread with the program open and I learned a lot. I was able to use a file I already had and successfully tweak it to the way I want it to be thanks to these instructions. Yay! I'll have more questions later no doubt but I really appreciate the time you spent creating all the screen captures with annotations and instructions, Talldude. Thanks, and thanks to everyone else that's been pitching in their advice too.

Is there any reason why I couldn't take the file for the 8-6 I modified tonight and transform it into the 10'er that I want to build even though the 10'er will have a radically different outline?

P.S. The screenshot of your 7-4 looks super cool! Did you create the deck pad pattern in photoshop?

I shaped a few all rounders for a friend of mine who has a few sup shops. He wanted a 9'6, a 10'2 and an 11'2 board. I designed the 10'2 then went back to the main board spec and changed the length to 9'6. Then saved it as that board. Then increased it from the 10'2 model to an 11'2 model and save it as the 11'2. He had all three cut, and they turned out fine.

I did that and it worked great. Thanks! I took the 8-6 that Tom Whitaker did for me and created a totally different 10'er out of it.

I was wondering what we should be shooting for when it comes to Volume Distribution on surf sups? My gut tells me to bring the volume a bit forward because we paddle them standing up. What do you guys think?

The first two images are for my redesigned 8-6 and the second two are for the new 10'er. Does the volume distribution look right to you?

Next question is how to make the very tips of the nose and tail look better. As you can see, the tip of the nose is really thick. I want to preserve the existing volume and thickness in the nose and tail but I want to make the tips look prettier. Would you remove the existing control points on the nose and tail and put new ones in different places? If so, where would you put them?

You should be able to do it just by moving the points closer and ajusting the slice it's only  on big fat race boards you need to add points

Been playing around with a shape and trying to determine the buoyancy line.
When the application prompts me the measurement window it's not clear
to me how do I get to the correct values to fill in.

Also, is any way to see the affect of different rider weights on the waterline?

[supuk]

just use the volume tab and use the equation that 1L is equivalent to 1kg or weight

Hi

This is how I use it :

My weight being 90 kilos, + 20 kilos for the board, paddle, clothes, leash, water, I get a total weight of 110 kilos

Hence, I need a 110 liters volume below the buoyancy line. I enter 110 liters in "volume", so I can see where the buoyancy line will be, and adjust the volumes of the board if necessary.

For a 50 kilos rider, I would enter 70 liters.

There is a little bug in s3D versions before version 9.0.9.8 : if you change the design (width or lenght for instance) , the volume below the buoyancy  line is recalculated, which didn't make sense. In 9.0.9.8 shape3d keeps the value you entered (110 liters in my example)

My current shape3d design 

16'x27" DW

PaddleSpot..... I'm dig'n that whole shape and graphic

I not sure about that rocker line. I'm guessing a DW shape. I had older Hobie unlimited that was surfable, but totally plowed water in the open ocean bump and was a complete dogs in flat water. They designed it for the 38 mile open ocean Catalina Island to Mainland race. That board only had 5" of nose rocker and 3" in the tail. From the DW boards I've looked at, I think you might want to smooth that rocker line out a bit, and just add a little flip near the nose. Here's one of Supuk pics he posted of his latest DW unlimiteds. Look at the rocker on them.

@TallDude

I never knew this topic on Shape3D existed here on the Zoner site. Probably because it was started in 2015 and the last post for this topic was in October of 2015 until today. I joined the Zoner site in 2016 so I'm glad Burchas started it up again because if he hadn't, I would have never seen it.

I've seen the Shape3D video tutorials for it, but there is no narrative in them. Without narrative, I couldn't make head or tails out of the program. I just wanted to say "Thank You" for starting this topic thread.

Since I mainly mess around with thickness and volume for custom builds (did that with my custom Hammer); maybe now I can retire my pen, pad and educated guesses along with my calculator.

NW, you are welcome. Just another piece of software to burn endless hours on. Fun to some, work to others.

Now it make sense. Thanks.
This is some nose you got on that board. I like it.

I not sure about that rocker line. I'm guessing a DW shape.

First TD, thanks for putting this thing together. This is very helpful.

As for the board. The baseline of the shape is a replica of the Naish
Maliko 2017. So it's an all-water.

I adapted it to a 16' added some rocker, 3.3" tail, 6.5" nose.
I re-configured the outline so it's less parallel for better maneuverability.
Narrower shoulders and a piercing nose and added a little more volume
to the tail.

It's going to have a recessed deck transiting to a flat deck towards the
tail. Right now the board is 313 litter but I expect to take it further down.

Just started it so expect a lot to change. I'm in Maui now about to test
all sorts of boards to develop the rail and bottom contours.

Shape3D is really fun to play with. I'm sure i'll tap this thread for some
more tips and tricks.
