charlieinolas Posted October 27, 2012 Share Posted October 27, 2012 hi all, I have a problem guys with modeling a simple geometry. I made a cylinder, and I wanted to cut out a hole in its surface (fig1). I created another cylinder, and used Proboolean and hole is nice, but when I want to chamfer the round edge of the hole, some nasty things appear probably due to vertices on the hole's edges that have no connection with cylinder edges. I tried to remove them, but it seems that doesn't do the trick. Could You help me out guys how to solve this problem easily? thanks Link to comment Share on other sites More sharing options...
salvador Posted October 27, 2012 Share Posted October 27, 2012 Before chamfering, convert to Editable Poly, enter Vertex mode and remove all edges and vertices that shouldn't be there. Try as well Reset X-Form and re-convert to EPoly, just in case. Good luck! Link to comment Share on other sites More sharing options...

charlieinolas Posted October 28, 2012 Author Share Posted October 28, 2012 (edited) Ismael, thanks for links however I think that these methods are a bit too complicated.This seems to be a simple story with cutting a hole in a surface, and using turbosmooth and cuts looks like an inconvienience and does not seem to be precise, I'd personally expect more from Max. Furthermore it's not a flat surface here. This is a bent cylinder surface with given number of polygons. Salvador, I deleted vertices that seemed to be unnecessary, but still it does not do the trick (pic). I also tried that script called 'vertex killer' but it seems that nothing happens. Anyone used it on max 2012? Edited October 28, 2012 by charlieinolas Link to comment Share on other sites More sharing options...
William Alexander Posted October 29, 2012 Share Posted October 29, 2012 Increase the number of segments on the cylinder, that will help some or make the "distortions" less noticeable. Higher density of the mesh on the cylinder may help also. Link to comment Share on other sites More sharing options...
salvador Posted October 29, 2012 Share Posted October 29, 2012 Can you post a pic of it in vertex mode and one in polygon mode clicking Edit Triangulation? Let's see what going on before chamfering. Link to comment Share on other sites More sharing options...
charlieinolas Posted October 29, 2012 Author Share Posted October 29, 2012 (edited) Here You go Salvador. (this is before deleting some of the vertices I mentioned earlier) Edited October 29, 2012 by charlieinolas Link to comment Share on other sites More sharing options...
salvador Posted October 29, 2012 Share Posted October 29, 2012 Ok. Clearly there are vertices messing up your chamfer. You can see them. I wonder if the vertical divisions on the object are necessary. If not, remove them before booleaning your cylinder and I'm pretty sure you will get what you want. If you are subtracting on a curved object, that's a different story; but still it shouldn't go wrong. Try removing the unnecessary vertices manually and see if that fixes it; you don't have all that many. Link to comment Share on other sites More sharing options...
charlieinolas Posted October 29, 2012 Author Share Posted October 29, 2012 Salvador, couple of post earlier I wrote what happened after deleting those vertices. There is a picture as well. It seemed to be better, but still wasn't flawless. Deleting vertical divisions is not a good idea, those are cylinder segments. Link to comment Share on other sites More sharing options...
salvador Posted October 29, 2012 Share Posted October 29, 2012 Found this thread: http://forums.cgsociety.org/showthread.php?f=6&t=932752&page=1&pp=15 I think it might as well solve your problem, since boolean (IMHO) will not. Link to comment Share on other sites More sharing options...
charlieinolas Posted October 29, 2012 Author Share Posted October 29, 2012 Thank You Salvador for Your time and trouble. Those methods You showed are somewhat similiar to those Ismael has given in the 3rd post. I studied this through and managed to cut out a nice hole and this way seems to be the best indeed if its about final result, however when we need to have a perfect circle on a bent surface it's becoming a bit more complicated. I personally thought that Max is able to cut out objects using Boolean in a bit smarter way than this but, as we see, things are as they are. Anyway, the work is done, and the aim is achieved. Thanks for all help and suggestions guys. Link to comment Share on other sites More sharing options...

charlieinolas Posted November 2, 2012 Author Share Posted November 2, 2012 Guys, I'm back here cause I have another problem. It's related to the topic so I'll write here without making another thread. I made a hook using 'line tool' and then extruded it. Somehow I can't chamfer the edges around - some of them chamfer differently than others. What's going on here? thanks for all help Link to comment Share on other sites More sharing options...
johannestiner Posted November 2, 2012 Share Posted November 2, 2012 Use the bevel profile modifier Link to comment Share on other sites More sharing options...
salvador Posted November 2, 2012 Share Posted November 2, 2012 Use the bevel profile modifier Yep! that little guy works a treat. Link to comment Share on other sites More sharing options...
charlieinolas Posted November 2, 2012 Author Share Posted November 2, 2012 but You mean Bevel instead of extruding the closed spline (shape) ? Link to comment Share on other sites More sharing options...
charlieinolas Posted November 2, 2012 Author Share Posted November 2, 2012 ok I found it under modifier panel. it seems to be working. thanks guys!! Link to comment Share on other sites More sharing options...
