 576.2 In reply to 576.1 Hi Rudy, Shell can be found under Construct / Offset / Shell. It is used to create an object with a "wall thickness". There are 2 ways it can be used. One way is to construct a solid of the specified thickness out of a surface: Here you see a surface to the left, and to the right the result of using shell on it to thicken it to a solid: One thing to be aware of is that if you have any tight curves or bends in your surface, you can't generally use a thickness value that is greater than the radius of the bend, otherwise this will cause the calculated surface to sort of fold back on itself. Then the other way to use shell is as a way to sort of "hollow out" a solid. On a solid you can select faces of the solid which will become openings, and then after you run shell on it, you will have an object with wall thickness. Here's an example - this is the result of taking a box, selecting the top face and then running shell: You can see there how the selected face becomes an opening, and all the other parts of the box became slabs of the specified thickness. It is also possible to shell a solid without selecting any faces, in which case it will hollow out a cavity within the solid. But generally when used with solids you first select a face for the opening. Let me know if you have any additional questions about shelling. - Michael Attachments:

 576.3 In reply to 576.1 Hi, it means that you can give objects thickness/walls. You can find it unter Contruction->Offset. Look at the picture for shell examples. 1. Object without Shell. 2. This is what you get when you use Shell. The object now have walls. 3. This is what you get when you select one face before executing the Shell command. The Object is open where the face was before. 4. Here i selected 3 faces before i executed the shell command. Strength was set to 1 for all Shell examples.

 576.6 In reply to 576.4 Thank you Sk2k, Have a good night...thank you for the trick on the revolve, still do not know the A axis... Tomorrow if you will remember Best, Rudy

 576.7 In reply to 576.6 There is no A axis. :) My faulty english misguided you. MfG sk2k Point of Inspiration

 576.8 In reply to 576.6 Hi Rudy, You might be thinking of the A axis on a CNC milling machine, which CAD jewelers use for cutting rings and two sided parts. The rotary "A" axis on my milling machine has a 4-jaw chuck that holds the material. It's set up in the CAM software so that that when the front side is done, the software automatically turns the rotary 180 degrees and then the the art work on the back is carved. -Jesse EDITED: 2 May 2007 by JESSE Attachments:

 576.9 In reply to 576.8 Dear Jesse, Thank you for adding things that are actually for me learning tools. Little by little I am getting there. I am trying to figure out the mill operations as well, if it is worth to get one to start or just send the STL file to a RP company and have my resins done, what about mistakes....I do not want that the company will charge me for a resin that is not correct....all these kind of questions in my head....plus learning to design in MOI (because I really think I love it, more than Rhino....MOI is simpler and very intuitive...I am trying to figure out how it thinks....little by little.... Also because I do not have to forget to earn my daily dough Thank you, Rudy Enjoying your tutorials as well!
