nut or groove problem

 From: mike (MIOHN) 8 Mar 2012  (1 of 9)
 hi, any help out there? I cannot create a groove ( in deutsch "Nut") on this surface where the cuts are going along. Whatever values I try it calculates very long and then nothing happened. I want to get a beveled gap between these surfaces. What I'm doing wrong here? thanks Mike Attachments:

 If I good undestand your problem (not sure) :) Sweep one rail (circle as profile) = a tube Boolean Diff = separated forms Sweep 2 rails (any curve as profile) = fill with any surface profile 20 seconds on my computer 10 years old, so 1 second with yours! ;) EDITED: 8 Mar 2012 by PILOU

 4992.3 In reply to 4992.2 thanks Pilou! this works! But still the question - why does the "nut" function not work? regards Mike

 4992.4 In reply to 4992.3 Maybe because The "Shell" or "Inset" Function works on a surface and not on a line ? Another thing : works with no Units System! It's more easy for tiny measures ;) EDITED: 8 Mar 2012 by PILOU

 4992.5 In reply to 4992.3 Hi Mike, is it the Construct > Offset > Inset command that you're trying to use for the "Nut" function? Inset can sometimes tend to get confused when you use it on a piece that is smooth to the surrounding pieces. That's because it normally tries to shrink the boundary around the surface by using offsets of the surrounding adjacent surfaces, but that method does not work when the surrounding surfaces are smooth, so in that case it tries a different technique but it's kind of unreliable. The next version of the geometry library is having some work done to its shelling/offset function so I have some hope that will get improved. Meanwhile see this thread for some other techniques that can be used instead: http://moi3d.com/forum/index.php?webtag=MOI&msg=3859.1 For something like this you may want to divide the object into 2 different solids (that are each capped) by cutting the full solid object by a dividing curve using boolean difference, and then fillet or chamfer the edges. - Michael
