How would I make this?

[TimelesslyTiredYouth]

Right Mamluk, bowl by Bethan Gray.

I understand how to make the bowl, may ways, revolve, T-spline/surface revolve and edit, ect...

What I don't understand, is how to make the Blue bits empty...

I thought volumetric Lattic, but it didn't go all as planned...

What would be the best way to model something like this?

[TheCADWhisperer · Accepted solution]

I would Revolve.

Cut one instance of each size.

Circular Pattern the features.

Depending on how you want the sides of the cut (straight or tapered to center) would determine how I would model the cuts.

Can you File>Export and then Attach the *.f3d file of your attempt to model the geometry here?

[TimelesslyTiredYouth]

Right, I'll import it when I can but for the time-being, 

are you suggesting I create the bowl line, revolve with surface tools by maybe 5-10 degrees (or T-spline, edit as necessary)

Thicken, by set value...

Create a sketch inline with the part of the bowl, emboss it to wrap sketch on bowl, then engrave,

and then use that bit of the bowl to circular pattern the rest of the bowl, by circula pattern multiplying it by the value that gets it to 360 degrees

Kind regards

Attach your attempt(s) here.

I would not use t-splines for this simple design.

Not that it matters too much but you want this bowl to hold fruit say but not water?

[Warmingup1953 · Accepted solution]

This may be one option:

Create plan view of the proposed pattern..(easier said than done!) and cut a Surface bdy via extrude and thicken:

just a thought bubble at this stage. I used Project Salvadore to trace a minuscule screen capture

Right it's a cultural project. Mix of indian and the Mamluk Dynasty (Like Islamic Geometry) and for the Indian, part, it will be designed as like a pottish design, with a similar design on the top. And then my own personal effect by making it work both ways (upside down and normaly)

For your curiosity with the water, When I make the bowl with Holes, I'll use Boolean subtraction with a normal Bowl to get those little gaps seperately to 3d print. Will then spray paint different colour, to input in. I want it to be optional on whther they can be in the bowl or not for my project. Like smthing you pop in...

For @TheCADWhisperer 

Problem solved sort off, I think the circular pattern is what I need. I will try to make the design when I get some free time, by revolving a curved line for a bowl only 15 degrees, make a sketch of one row of the ovally thingies, use emboss tool too make it curve on surface (if doesn't curve on surface I'll use thicken) use trim offset (or engrave/extrude) then use the circular pattern tool, to make the full circle with that pattern and I'll do any chambers,chamfers and fillets before I circular patter. I will constrain starting sketch and add parameters to change size of the bowl, I'll figure out how to keep the parameters of the first row sketch with the bowl size along the way

I will report back to the thread if this works after hearing @TheCADWhisperer first advice, otherwise I will ask necessary question to proceed

Sleeeeepy Regards

Right sorry, reply didn't load for me till now didn't see it yet sorry!

[TimelesslyTiredYouth]

This is perfect exactly what I wanted, thank you for the knowledge! Now I know how to Make Volumetric Lattices with curved objects, and @TheCADWhisperer circular pattern advice has unintentionally, given me an idea to solve one of my other issues in another design I have.

When you save Project Salvador, Do you mean you imported an image of the top view of the mamluk bowl and traced it?

*I though Project Salvador personally wasa workfolow to repair optimize and prepare 4d mesh objects for 3d printing ?

**3d mesh

I've not had the time to play around with Project Salvadore. Very cool! 

[TimelesslyTiredYouth]

Can someone please give me some context, I'm internally dying without it in the backorund... Is it an automatic tracer?

[johnsonshiue · Accepted solution]

Hi! There are multiples ways to do this. I only focus on creating the tool to cut the pattern. This approach requires two circular patterns. The first one is a 90-degree circular pattern of the tool. After the bodies are created. Use Scale command to reduce the body size accordingly. Then pattern the bodies around full circle. Lastly, cut the bodies from the bowl.

Many thanks!

Thank you very much, I'm sure this will be a life-saver in the future!

Project Salvador is a real Game Changer! (Note to Self....Don't over-use it!)

Project Salvador (Beta) Intro 

[TimelesslyTiredYouth]

It really is, Released in 2018, can't believe I never knew about it before! (Note to self, don't use it, constraining complex sketches and adding parameters to match, Hell) It's got quite a way to go, but it really is a game change!
