  Re: x210c01 ChromeSilver Drill 4 x 4 x 7
 
(...) None I know... (...) The official way is to ask a number to a LDraw admin. That said there are numerous parts on tracker named px... (would be px210c01 here) (...) Yes you should be able to use stacked cone primitives. As Travis suggested the (...) (16 years ago, 11-Dec-08, to lugnet.cad.dat.parts)
 
  Re: x210c01 ChromeSilver Drill 4 x 4 x 7
 
(...) Just to refresh my memory ( I haven't done any parts since 2951) The 48 primitives divide a circle in 48 straight lines, right? That would for a 60 LDU diameter mean that each straight line is approx 4 LDU's long, so using coneshapes each 4 (...) (16 years ago, 11-Dec-08, to lugnet.cad.dat.parts)

(...) I do not understand correctly what you are saying. If you use a cone primitive you can stretch it in all direction. There is no need to use "about 40 cones". A maximum of 10 should do the same! You should use for this the program "cones and (...) (16 years ago, 12-Dec-08, to lugnet.cad.dat.parts)

(...) Welcome back! (...) I agree with Mikeheide, since the total curvature is low I think 6 cones would be more than enough! (...) Seems a good approach. As for the edge line between screw and cones, Isecalc will provide it instantly! (It would be (...) (16 years ago, 12-Dec-08, to lugnet.cad.dat.parts)

(...) When the curvature is the only concern, then yes, but I have to take the screwshape into consideration, the closer I am to the ideal curve, the easier it is to calculate the screwshape and avoid holes in the part. Furthermore when thinking (...) (16 years ago, 13-Dec-08, to lugnet.cad.dat.parts)
