Your 3d Modeling Workflow: Idea to Print

[Geoff]

Can you move the bottom of the object to be under the build plate plane?

Simplify 3d can also do a lot of that model repair however I have never used it. I'm not sure if it is better or worse than Blender/Netfabb repairs...

Blender exports with an origin you set, so yes. You set the origin of the object somewhere higher, drag it below the Floor (ie then set it to location to 0,0,0 )

You then press CTRL-A and RESET the Location. The model stays in place but its co-ordinates are now reset to 0,0,0

When you export it, it will export it as 0,0,0 being the build plate and whatever below is below.

Yep, I tested this ins S3d after posting. The preview showed that it won't print what is below the build surface.
