Thank you for this informative video. May I ask if how about the gold bar 24k is it possible to define the requirements?

I am having issues fixing the intersection. When I select and pull down the rail curve and pull it down, the only thing that moves is the black curve line, not the whole intersecting rail.

This is a fantastic tutorial - easy to follow and everything explained clearly - I've already used the skills I picked up here to design and fabricate my first engagement ring (couldn't have done it without you, Jack!) I do have a question about the network surface function: why is it that in the video the A and C points run down along the shank, whereas when I do it it frequently cuts straight down along the side profile of the ring? It creates a seam that won't allow me to use loft to create the internal surface. I can duplicate and join the edge, but the seemingly arbitrary nature of where it puts points A and C is really bothering me... 😅

What % allowance do you recommend for Mould/Master? Thank you for the video!

Your videos are so helpful to me. Will you be making more soon? 🙏

When I make any jewellery design its weight decrease is unreal. Example - A customer need a 2.5gm ring, and i make it 3gm on matrix9 but after casting its stand for 2.1gm ( Remember no finishing only casting weight) Please help me I need urgent solution 🙏🙏

Very helpful

Hi there - When I did the edge analysis at the end, somehow I have 12 naked edges? Anyone how know to fix this?

It's weird because I get a must lighter weight on the finished pieces than what was calculated. For ex, a piece that showed a volume of 310.8 mm3 (so 4.22g in 14k according to the calculator) ends up weighing just 3.4g once cast and polished. I understand polishing will take away some gold, but surely not that much..

Thanks a lot mate! Appreciate :)

Hello teacher, thank you for this video. I have a query, there are times that it allows me to make the duplicate edge and other times it doesn't, the curves appear as joined, and that doesn't allow me to make the loft on the inside face above. I hope it is understood. Thanks for everything

thanks for this!

Brilliant, thank you so much for this!

Truly, your tutorials are fantastic. Easy to follow and understand. Please upload more, would so appreciate it. 😊

A fantastic tutorial…appreciate it very much!

Super super helpful and informative! I found that an easier way to finish is to cap the entire thing after NetworkSrf, making it a solid surface, and then boolean out the middle of the ring. Duplicate the bottom 2 edges of the top half of the shank, and then just sweep1 along the inner ring rail. Gets rid of the lofting steps. :)

Thank you so much! Great method and super pleasant presentation!

Thank you, your teaching method is gold 😊 every single step and explanation left me feeling like I could actually do this. Other tutorials and even my real life certified teacher left me feeling dumb and discouraged and hating CAD projects.

Hi Jack and students. I am looking into paying for some lessons using Rhino, for jewelry design. I am looking at other instructors as well. My experience is as a CAD modeler for the Plastic Injection Mold industry. I have been using Cadkey for about 30 years. I have an opportunity to get out of the mold business and into the jewelry design business. Jack, please tell me why you are the guy for me. I do like the way that you tend to not just rely on visuals only. I like to know the angles that I am rotating, not just always free-floating things. Should I lighten up on this visual thing?

hey man, great tutorial! I just seem to have a hard time doing a boolean ( not just with this exercise tho) is there any chance you can help me with it? thanks.

So usefull! Thanks a lot.

Nice tutorial, thank you! For the origin, I just enter 0 followed by Enter. Regarding the design of stone settings, I'm a n00b. I wonder: Why do you not make the chamfer match the stone, and why do you not put an undercut into the prongs? My guess is that 3D printing is not precise enough, plus variances in the stones, and it's better to do that by hand when doing the setting. But I really have no idea.

Boolean difference failed. What are the properties of the "medallion" 3d object that makes it different from a 3d box I draw in Rhino? With the 3d box any text drops to the "bottom" of the box... ......... There is something very specific here that you assume is already in place.

So helpful, thank you so much

Hello Do you have any other way of smoothing rings? Like Zbrush? Bcos 3d coat screws up the topology of the ring and it is not renderable. Any other way to smoothen the rings with perfect topology?

Hey man, thanks for the tutorial; im having a hard time using boolean union to make it a single object; and getting shading problems where the shank meets the start of the prongs

hi there!! tks for your videos, are so hel´ful por me, but i have bunch of doubts... i design and manufact jewerly and 3d is nes forme, i have lot of problems with stones.. i mean, the stone mesure most be .2 big on the design rigth? but i think that the hole of barrens arent enough because the stones just doesnf fit, so any advise of you could be very helpful tku very much

Helpful class🎉

Thank you very much 🙏

Thank you a lot. It is very detailed.

Hello! could you please give us the conversion formulas for 10K and 24K? Thank you for the helpful spreadsheet!

Another great teaching video. Thank you

Thank you for the clear instructions. It helps to take the guess work out of CAD to product.

Hello! Thank you so much for these videos! I'm having trouble fixing the intersection. When I use the gumball to drag the rail curve down it only moves that curve by itself and not the actual object of the twisted prong. Do you know what I may be doing wrong?

Muchas gracias

Boa noite! Parabéns pelo vídeo! Tenho dificuldade pra unir as garras no aro....

How would I check the karat weight if I put stones in the piece ?

EXCELLENT, EXCELLENT!!!!

really well educated tutorial! thank you!

Thanks so much, this was really helpful

Try importing as a obj file. You won't get those strange artifacts that a STL file has. Scale to 2000. Do your smoothing, etc, then export as STL. The results will be MUCH better!😀

I scale 99% of my models to 102.5% Have you ever used 3dCoat? It is an excellent program for importing your (obj) rhino models into, then doing all your boolean operations. Then you can do a smoothing operation and export to STL for RP printing. No boolean fails and the model is perfect! Eric Marvets has an excellent tutorial on this if you are interested. ruclips.net/video/HwyGIEssfqc/видео.html

Thank you. You should become the teacher. Easy explanation ❤

thank you for your clear explanation and for sharing the spreadsheet, very helpful!

thank you

Why can't I make a curve network? It keeps telling me "Unable to sort curves. Select curves one at a time. Unable to use this curve network."

Just starting to learn Rhino. This was extremely helpful. thank you. How do I get the stone downloads?

One more time bro, Thank You, i hope you'r well!

I've been looking for this for months. you have no idea how much you have helped me, thank you for sharing this knowledge. Happy birthday!. let karma come back to you

شكرا لك
