|Best practices for modeling with 3d Max [message #111579] Thu, 05 March 2015 00:24 UTC
I have used 3d Max for some time, but never for 3d printing, and I had a couple of basic questions. I use 3d Max 2011.|
My first question is about the smoothness of a somewhat cylindrical lathed object.
If I create an object by drawing a line-shape and using "Lathe" you have a "segments" setting. For a low setting of "16" segments, the smooth cylindrical surface will probably look segmented. I could crank that "segments" setting way up (but of course the mesh becomes more complex and Max runs slow). I am creating a cylindrical boiler for a steam locomotive, and want a nice smooth curve. Is there a best practice for what to do here? Are there any smoothing benefits to converting to an "editable polygon"? Can I assume my "smoothing groups" at the mesh level do not help when modeling for printing? I know I could always crank the segmenting up on my "Lathe" modifier, but I'm wondering what the best solution really is.
My second question is about Boolean vs Attach.
I need to add a bunch of little rivets and pipes on the surface of my boiler. As long as my sub-objects all overlap as they should, is there any difference between using "Attach" and "ProBoolean" to ultimately bring all these little pieces together in the end? As a simple example, if I created a cylinder and wanted to put little rivets on the outside of that cylinder, could I use small spheres for my rivets, make sure they overlap, and then use "Attach" or "ProBoolean" to unite everything in the end?
I'm excited about trying my first 3d print.
