I've been looking at Shapeways for a while, and I've got a bit of experience with Blender. More recently I've been learning Cheetah3D for the Mac. I've been enjoying the breath of fresh air that the interface brings compared to Blender. My Dad is a model railroad fan and has a decent sized HO scale layout. As a project to help me learn Cheetah, I'm hoping to model my parents' house, have it turned into a physical model by Shapeways, assemble and paint it and present it to my Dad as a birthday present. His birthday isn't until August, so I've got plenty of time to work through learning curve. I do have a couple of questions for those more experienced... I believe that their house which is, I believe, some 40-50 feet long would work well within the limits of the Shapeways size limit when scaled down to the 1:87 HO Scale. Am I correct in assuming that the house should be modeled as a number of separate pieces? Each of the walls, plus a base and roof? How detailed can the model be? Ideally, I'd like to have reliefs where the door is and for the grooves of the siding so that the texture will show up even afer they've been painted. Related to the above, I see that some of the materials feature a .2mm detail. This seems like it would be plenty, but is this material strong enough to serve for a model railroad building? I've seen several folks that have done model railroad parts and buildings, any pointers for the design from you guys (best ways for the pieces to fit together, recommended adhesive, limitations with putting LED lights in the inside, etc.) would be much appreciated!
