 5316.2 In reply to 5316.1 Hi Rachel - the problem here is with the layout / formation of the curves - in order for Network to work right the curves must form a grid layout where they can be unwrapped to a 2D pattern. It's similar to how on a 3D globe curves of longitude and latitude unwrap to horizontal and vertical lines on a 2D map. In your current layout here it's not possible to get a 2D representation because of your 2 long curves crossing each other and then connecting back to the same base ring. You can solve this by splitting the long curves (use the Edit > Trim command to cut them) so that they will share endpoints where they come together making a kind of "pole" region similar to the north pole or south pole on a globe. Check out here for some links to previous discussions about Network curve layout: http://moi3d.com/forum/index.php?webtag=MOI&msg=4384.4 And one that applies to your particular case: http://moi3d.com/forum/index.php?webtag=MOI&msg=1778.6 - Michael

 5316.3 In reply to 5316.2 Ah fantastic, thanks! I understand now, and I'll try breaking up the lines tomorrow. Is there a more suitable tool for this purpose? I do eventually want to have the bottom of the shape filled in to make a solid (the bottom is a complicated shape on its own, the ear is eventually to be made from foam and fit tightly over a small knob on a headset). I was planning on adding the bottom later on with boolean transforms.

 5316.4 In reply to 5316.3 Hi Rachel, > Is there a more suitable tool for this purpose? For more organic style models a polygon modeling toolset can be a better fit in general - they use a much different modeling approach which is more about manipulating a cage of points and not about drawing curves like MoI's construction method. The "draw curves" method that MoI uses is particularly strong when much of your objects are defined well by 2D profile curves like they are for mechanical objects. Organic objects have a lot less 2D profile nature to them and so MoI's approach becomes less of a fit for organic models. If you do want just a dome shape like in your example file though, drawing in just one profile curve and using Revolve is a better tool for a symmetrical type rounded tip thing like that. That would look something like this - just draw in one profile curve that's just a half of one of the ones you currently have like this: And that's all you need actually, no extra circles - then select that one half profile there and run Construct > Revolve. Pick the revolve axis starting at the endpoint of the profile and then coming downwards: Revolve then forms a surface by swinging the profile around using the axis line like a hinge, it will automatically make a circular result to it: But I'm not entirely certain if you were actually wanting tips on building a different kind of shape than what you had in that example file - these tips for revolve here are on that particular kind of dome-like shape that you had in that file. - Michael

 5316.5 In reply to 5316.4 I split the lines like you suggested and Network did exactly what I wanted! The shape is not rotationally symmetric so Rotate isn't suitable... unless I can then morph the resulting shape, which doesn't seem possible in that case although I may well be wrong. thank you, Rachel

 5316.6 In reply to 5316.5 Hi Rachel - there is a command that is new for v2.5/v3 called Flow which might be able to handle the morphing for you of a uniform revolve. Check out here for some examples: http://moi3d.com/forum/index.php?webtag=MOI&msg=4856.2 I'm still not sure exactly what kind of end result you're looking for though, but if it's something like making the revolved shape follow a path then Flow could work for that - you would draw 2 curves, a line going down the middle of your revolve for the base curve, and then a bendy curve for the target one, then select the revolve and run Transform > Deform > Flow, pick the "down the middle line" at the first prompt in Flow and the bendy one in the second prompt and it will generate deformations like this: - Michael EDITED: 9 Aug 2012 by MICHAEL GIBSON Attachments:
