Hash Fellow robcat2075 Posted November 10, 2018 Hash Fellow Share Posted November 10, 2018 I'm making a project that involves a solid-spoked wheel, much like many car wheels are today without hub caps. To cut down on the modeling I used some lathing and duplicate techniques. I based my lathe outline on a rotoscope diagram. I used two CPs at every corner to make a sharpish but still-beveled edge... This wheel has 8 spokes (with 8 holes in between) and a bump on each spoke. The easiest way to model a round bump or hole is to stitch it in on splines between two other splines. That means a minimum of four splines across for each instance of a hole and a spoke with a bump... To support 8 holes/spokes, i need to do a 32 cross section lathe. (You set that at Tools>Options>Modeling)... However, the five-pointers around holes and bumps prefer not to be stretched very far or around large turns. I'll need extra splineage where I've drawn it in... To create those spline I put some extra CPs in the lathe outline where i wouldn't normally need them for a straight spline. I broke up one spline crossing and spread the edge splines apart to start the pie-shaped hole... Connect the front and back edge splines... The corners are 6-points and need to be split into two 5-pointers. I add a CP to the middle of each front-back spline with the Y key and stitch in a middle spline... The five pointer patches are still visibly wrinkled from having to turn a large angle. I stitch in a new spline around the hole between the middle spline and the old square edges and hook in a new radial spline at each corner at the wide end of the hole... Now the 5-pointers don't have to do much curve work. I stitch in the oval spline for the bump on the spoke and that gets me one finished hole and spoke... I could do this seven more time around the wheel, but there is an easier way... I cut out the 5 lathe sections that contain this new modeling and deleted one lathe section on the edge to leave hanging splines... I grouped that, set its Pivot to 0,0,0, the copied, pasted and rotated the pasted part 45°... I connected each hanging spline to its immediate neighbor in the old section. This new quarter section gets copied, pasted, rotated 90° and connected to make a half section. The new half section gets copied, pasted, rotated 180° and connected to make a complete wheel. 1 Quote Link to comment Share on other sites More sharing options...
R Reynolds Posted November 21, 2018 Share Posted November 21, 2018 Nice modeling, Robert. It looks to me like your making a one of those old, railroad hand (pump) cars. It probably comes too late but if you can use any more detailing, I can offer all parts from this one. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted November 22, 2018 Author Hash Fellow Share Posted November 22, 2018 Thanks, Roger! I better do my own modeling for my contest entry, though! 😀 However, I do hope to see an entry or two from you in Planes, Trains Automobiles. Three weeks to go!
