 greetings from a long-time lurker, I really admire the work presented here and love Moi! Until now I've managed almost everything from scratch, but I don't know how to do this simple task. I'm trying to create an extrusion that extrudes towards a point. the idea is to create a shape resembling a teddy bear, projected onto a sphere and then extrude 1mm inwards towards the center of the sphere. Hard to explain, but I think you'll know what I mean. I've attached a flat projection of the "teddy" I want to create and projected this onto the sphere too. I bet the answer is simple and I'll look a real idiot in a few moments ;) Thanks for any help in advance. Regards, Harri Finland Attachments:

 4791.2 In reply to 4791.1 Hi Harri, One way I can think of is by creating two spheres 1mm apart, then insert and extruded solid version of the teddy bear (>1 mm) and then boolean them together to get the surfaces you need. You may need to join them to create a solid. Or, project the teddy bear onto both spheres and then loft or blend the resulting profiles to get what you need. --Luis

 4791.3 In reply to 4791.2 Thanks Luis, I think this would not create a teddy that's outline tapers towards the center of the sphere? The teddy should be be cut perpendicularly towards the center point. Harri EDITED: 15 Dec 2011 by HJOY

 4791.4 In reply to 4791.1 Hi Harri, If I understand you correctly, there are several ways to do this in MoI. Attached JPEGs are showing one way that I would use to do this. Hope this is the result you are looking for. Michael T. Michael Tuttle a.k.a. mictu http://www.coroflot.com/DesignsByTuttle

 4791.5 In reply to 4791.3 I see what you're saying. You could possibly create a lofted version of the teddy bear that starts small at the center of the sphere(s) and finishes the size you want around the outermost one and the boolean the results. --Luis

 I'm thinking: Flow with Projection!

 4791.7 In reply to 4791.4 THanks Michael, Looks beautiful but not quite... Your teddy is extruded along a line; it should "vanish to a point". Harri

 Hi Harri, Sorry, I missed the taper inward part of you question. You could try a sweep with pointed end like this: You would need to sweep pointed end for main face and each one of the eyes. Then do the boolean intersect of the main body to the shelled sphere as I mentioned previously. Then boolean difference the eyes from the head. Then unhide the copied solid sphere, and do the boolean difference with the newly created teddy head. Does this make sense? Michael T.

 4791.9 In reply to 4791.6 Hahaha, thats a good one MajicMike. made me think of something along those lines. I think flow to the inner sphere and then slice and join it with the outer sphere 1mm apart should probably work, although I don't know how the flow command would actually affect the taper, which Harri is very interested in solving. Maybe Michael can give some insights about whether or not flowing the teddy bear would actually achieve the vanishing point that Harri is looking for... --Luis

 Take one big bear, take a very little bear at the vanish point Make a Loft Direct between them Intersect the volumes ;) If you want a rounded bear take a sphere tangent to the middle of the face's bear ;) EDITED: 15 Dec 2011 by PILOU

 4791.11 In reply to 4791.10 For the taperd bear, dont forget sweep "with pointy end".

 4791.12 In reply to 4791.11 Yes yes yes!! Thanks everyone, nice solutions. I'll play around and try them. Harri

 4791.14 In reply to 4791.4 And I think Michael T was on the right track there with his first reply since he did use shell in there as well. The difference is that if you want the "side wall" parts to also follow the surface normal then you'll want the side walls to also be generated as part of the shell as well. If the side walls come from a boolean with an extrusion then those areas will have the one uniform directional quality of an extrusion rather than the "follow the surface shape" type of result that shelling a surface fragment will give you. Hope that make sense! - Michael
