Sorry to overkill the helix topic

 From: designer 4 Apr 2012  (1 of 14)
 My apologies for bringing this up again as i know it has been talked to death. I am currently using the trial of MoI and the reason i want to buy the software, silly as it sounds is because i want to design something like the da vinchi air-screw. its a conical Helix, and i'm have no joy designing one and ive spent my whole night combing this forum and nothing has helped. Please a kind a appeal to the highly respected creator of MoI and all others too, to assist with a simple Helix tutorial that is as fool-proof and simple as extruding a shape. Please assist. How do i go about making something like this Of course, its the sloping and vortex geometry i am trying to learn and that has brought me here. Some please kindly assist. Thanks. Attachments:

 5048.3 In reply to 5048.2 I think the twist function is only in version 3 beta or the 2.5 mac beta. not in the 2.0 trial :)

 5048.4 In reply to 5048.1 Hi designer, also check out some of these previous posts about creating a screw thread from a helix, they could show you another possible way to do it: http://moi3d.com/forum/index.php?webtag=MOI&msg=767.2 http://moi3d.com/forum/index.php?webtag=MOI&msg=490.36 Also another one here: http://moi3d.com/forum/index.php?webtag=MOI&msg=4623.1 But one approach is to first draw a helix path curve, which you can do with the Helix command, look for it under Draw curve > More > Helix. The Helix command will also let you create a tapered helix, set the "Tapered" checkbox option that shows up inside the command options and that will let you pick both a start radius at the bottom of the axis as well as a separate radius for the end of the axis line to make a tapered helix. Then once you have the general path, draw another curve hanging off of it and use the Construct > Sweep command to build a surface that follows the path, that's the part that is shown in the screw thread discussions above. Set the "Twist = Flat" option inside of Sweep to avoid having the profile do any banking as it travels along the path. Let me know if you are still stuck after looking at these other examples. - Michael

 The easiest way to create something like that IMO is to draw the helix first, then a straigth line in the center that is your axis and then simply do a loft between them: For a bit of thickness you can use the Shell command afterwards and then boole your central axis cylinder with the result... Did something similar a while ago with a smaller helix in the center... (couldn't make the second attachement viewable inline with the message edit function...???)

 5048.6 In reply to 5048.5 That is sweet Tom! I never thought if that and it makes a nice surface! :)

 Ladies and Gentlemen, it is a pleasure, and i am a believer. just trying to load up my debit card now to pay for the V3. All methods worked beyond my expectations. It's amazing how much power can be found in the dumbfounding simplicity of this ware. Michael, all i can say is keep it up. The power of nature that creates things is powerful and yet so simple, AND effective!!!!!!!!!! - look around if you don't believe me. In this simple package, you give us the ability to create things of our imagining and inspiration. Truly remarkable. Please confirm i can pay direct for the v3? Greetings from Nigeria.

 5048.9 In reply to 5048.7 Hi designer, I'm really glad that you like MoI! > Please confirm i can pay direct for the v3? Yes, you should be able to order it directly, you will probably need to use a credit card that has a billing address inside of your country though. Also v3 is not completed yet, it's still under development and is in beta release, it will still be quite a while yet before it's finished up and so right now it's only version 2 that you can actually purchase for now. - Michael
