I sculpted in Sculptris. Then I output to a OBJ file. When I uploaded to Shapeways, the size was 0 and the volume was 0. How do I control the size (scale) of the output file? There don't seem to be any controls for looking at the dimensions. There is a scale button in the program, but it doesn't seem to have associated dimensions. Thanks for any help. Alan
You can try opening it in Meshlab.. Import the .obj, click Show Layer Dialogue(Looks like a sheaf of papers) on the top menu bar. Then click Filters/Quality Measures and computations/Compute Geometric measurements. Values will show up at bottom of Layer Dialogue box
Sculptris doesn't do any sort of scale. You can do as Fredd suggests. I usually import my item into Blender to scale and hollow.
I agree with Michael about Blender. It has some good import/export options, along wtih some nice tools for 3D printing purposes. It is a big learning curve if you want to get really good at it, but for just the basics its easy. Besides there is good advice at #Blender on the irc channel Freenode.
Grab yourself a free copy of NetFabb Basic. Load up your obj file. You can then scale your model to get to the size you need. To save the re-scaled model file, head to the Part menu and Export Part Paul [hr]stop4stuff Modeller for hireShapeways ShopTwitterYouTube[hr]
