north Posted August 17, 2010 Share Posted August 17, 2010 on the exercise fw-190 fighter jet, watching the video and i am trying to understand on how he calculates and draws/traces the tires, he is using advance manipulator to manipulate the pivot then he starts position it and that it has to be in the y-axis. im trying to understand but it is hard, also since the problems with these videos is that the sound and video are way out of sync. with each other. he starts doing this in the second part of the lecture around the 11 minute mark to finishing around 15 minute mark.

Hash Fellow robcat2075 Posted August 17, 2010 Hash Fellow Share Posted August 17, 2010 I haven't watched that vid but here's the simpler way i'd do it. you know how to lathe a circle by lathing out a cone and deleting all but the bottom ring? you get a circle that's flat on the horizontal. Make a circle that way, then rotate the circle 90° so it's vertical then scale it so it's about as wide as the width of the tire tube in the image. Not as big as the whole wheel, just as wide as that rubber tube cross section would be. Next, move it so it's as far from the vertical axis as the inner edge of the tire is from the axle of the wheel in the picture. pick one CP, hit lathe and you get a torus for your tire. rotate and move it into place. Does that help? Quote Link to comment Share on other sites More sharing options...
north Posted August 18, 2010 Author Share Posted August 18, 2010 i will try that, when you say Lathe? what do you mean exactly? i probably been using it but dont know the terms well yet, lol. lathe you mean probably hitting the arrow with the "+" sign next to it and creating control points? also, where did you learn this method?

Hash Fellow robcat2075 Posted August 18, 2010 Hash Fellow Share Posted August 18, 2010 I believe the first use of Lathe is in Ex 9 "Flower Power". Do that if you haven't already. Quote Link to comment Share on other sites More sharing options...
north Posted August 18, 2010 Author Share Posted August 18, 2010 i did, i believe it was used to create the top of the flower yellow bud. i will check it out again. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted August 18, 2010 Hash Fellow Share Posted August 18, 2010 And the whole stem! Lathing is is one of the most used tools. Part of A:M modeling is seeing something like that tire and saying "ah, a lathed shape. Easy!" To get a circle you can lathe any spline, delete everything but one spline ring, and that spline ring that's left... a circle! Quote Link to comment Share on other sites More sharing options...
north Posted August 18, 2010 Author Share Posted August 18, 2010 hmmm, scale it so it's about as wide as the width of the tire tube in the image. Not as big as the whole wheel, i am not too sure if i did this right, now i am getting a huge circle here, i attached a pic of it. Quote Link to comment Share on other sites More sharing options...
north Posted August 18, 2010 Author Share Posted August 18, 2010 okay, never mind. i figure it out. i tried the video again one more time. and found out that he just made too many errors and started over on creating the circle for the second half of it portion....sigh, if only i figure that out sooner.
