CAnnondale Posted August 24, 2011 Share Posted August 24, 2011 Hi Guys, I need some help in here. I want to draw a dresser coupling and I am stuck on how and where to start. Can any body again extend their knowledge on this matter. I really do not know how to start. I have attached a link and an image as a reference, Thank you & appreciate it much.

CAnnondale Posted August 24, 2011 Author Share Posted August 24, 2011 Appreciate if you could give an .ipt on how to do it. Quote Link to comment Share on other sites More sharing options...
rdharvey Posted August 24, 2011 Share Posted August 24, 2011 Could you extrude a solid profile and the n create 3d sketches to produce a surface and then surface cut to leave the *wavey profile*? Quote Link to comment Share on other sites More sharing options...

Be_cool Posted August 24, 2011 Share Posted August 24, 2011 I'm just joking...if no one can solve this problem J.D. Mather will do it in 10 minutes. Quote Link to comment Share on other sites More sharing options...

rdharvey Posted August 24, 2011 Share Posted August 24, 2011 If you create your construction geometry as shown in the image you can select the points for the curvature of your surface .... simple way of doing it. once your offset surfaces are made you can cut from you circular extrude your surface to leave a wavy effect.. if jd has another way of doing it then fair enough.

Be_cool Posted August 24, 2011 Share Posted August 24, 2011 HAhahahah loool!!! That's what I'm talking about Quote Link to comment Share on other sites More sharing options...
rdharvey Posted August 24, 2011 Share Posted August 24, 2011 depends what approach you want to take it could be produced using simple revolve - cut - mirror and loft functions... surfaces look fancy though lol Quote Link to comment Share on other sites More sharing options...
rdharvey Posted August 24, 2011 Share Posted August 24, 2011 oh JD has replied. lol didnt take long Quote Link to comment Share on other sites More sharing options...
JD Mather Posted August 24, 2011 Share Posted August 24, 2011 I'll try to post an actual solution when I get a chance, but a bit busy today. The wavy spring doesn't look right and more complicated to create. The I think the key to this one (to simplify) will be lofting to faces (not sketches) and set tangent, to avoid having to create 3D sketch intersection rails, but even that shouldn't be too difficult. (said the one who hasn't tried yet) Quote Link to comment Share on other sites More sharing options...
CAnnondale Posted August 24, 2011 Author Share Posted August 24, 2011 Hi guys, Good morning. Thank u all for the replies. Anyway, i did try to create it using loft surface using a 3D sketch. It did somehow shows that shape but on some portion of the surface it is not 90deg perpendicular. I will post an image when i get to the office.

CAnnondale Posted August 25, 2011 Author Share Posted August 25, 2011 Here is the image of what I have done. Issues encounter: 1. Can not get the 90³ perpendicularity after lofting to surface. 2. Can not thicken the surface to more than 4mm. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted August 25, 2011 Share Posted August 25, 2011 I don't see the Extrude I suggested earlier in that picture? There is a planar feature for the clamping face of the fasteners. That needs to transition (Loft) to the cylindrical face. Attach your file here. That planar face is easy to create and needed for the tangent loft. It is hard to say from the pic if the other face is cylindrical or conic, but either case is easy to model. The trick is to then get the tanget transition Loft from the planar to the cylindrical (or conic) feature. It may or may not require a 3D sketch for rails. (I don't see a need for surfaces). If the 3D sketch is needed I would create it using an intersection of two 2D sketches. Post your file and I'll fix it up. Quote Link to comment Share on other sites More sharing options...

JD Mather Posted August 27, 2011 Share Posted August 27, 2011 Clamp_jd.zip My first attempt to understand the geometry. Now that I see where I'm going wrong, I'll try to post back in a couple of days with another solution. Quote Link to comment Share on other sites More sharing options...
pluissand Posted September 7, 2011 Share Posted September 7, 2011 I think that this a good aproximation Quote Link to comment Share on other sites More sharing options...
CAnnondale Posted September 7, 2011 Author Share Posted September 7, 2011 I think that this a good aproximation Ummmm... Close but that is not actually the shape of the curls. Quote Link to comment Share on other sites More sharing options...
