Really, that fixes it? Never would have guessed.
Still not a real curve, no matter how many times you roll your eyes.you have to use another software if 100% true curves are required.
simple as that.Is 100% curve even possible?
yeah.. it is..
(though on screen it's not totally possible because pixels are square.. when output to a robot saw though, the cuts can be absolutely true)[edit] a sort of similar problem comes up in nurbs apps.. the surfaces shown on screen are actually render meshes.. basically, they look like sketchup surfaces.. but the underlying calculations are there so when output, the true surfaces will be cut/printed)… likewise, when inferencing and what not, sometimes things will appear not to line up in the nurbs app because of the render mesh being used to represent the surface whereas intersecting with the surface is actually determined by the true surface… basically, with nurbs apps, learn to trust the wires and ignore the surfaces
Knowing the 3d printer capabilities you can tweak the final output. All of my models for my side business Hobby Fuzion http://www.shapeways.com/shops/hobbyfuzion are made in Sketchup. Designed for the tabletop, the models are perfectly round to the touch and I use about a 64 segment circle for these to conserve polygon count (some are old and the early Shapeways had tighter poly limits that they have increased over the years). The original .STL plugin was from a request I made on the old @Last forums years ago Course while the sample models are not very detailed on my shop (that was mainly due to resoluztion limits, not lack of Sketchup capacity), the test planet/moon model was a hollowed half-sphere base in Sketchup and surface detailed in Zbrush from a picture of the Moon made into an alpha brush. I've also made some jewlery for familiy (not shown) usine Shapeways silver printing that had curves without facets so it's doable.
