I cant see my model in Netfabb

Recommended Posts

it seems the same problem you can have in sketchup. when you zoom/pan/rotate, part of the model ic cutted away? if it is so, maybe it is a problme with the scale of the model. a revit model maybe is in meters or feet, a 3d printer model is usually in millimeters, so the cut plane in the rendering engine could behave erratically...

in sketchup it easy to work in meters and then scale all when you are ready.

I had a lot of problem in cura with the 3dpreview window, it was always black. after I disinstalled some software from my win7 64 PC suddenly it starts working like a charm!

I hope this help...

thank you.

i clicked apply to repair in netfabb and the models shows up perfect.

then saved it out as STL and brought it into skeinpypy, i dont have daids cura installed on my office computer yet. :cry:

And the same thing is popping up, i can only see weird small clicing of my complete model ??

you can scale in netfabb, aftter the repair and then export the stl.

by the way, I'm an architect and so your experience with revit models is interesting. I think that a lot of info that revit put in the model is really not used (if not un-healthy) by our 3d slicers and printers.

OT:

at this point you need a SHELL command (like in inventor or solidworks or maybe the sketchupp version could work). a shell command remove all the internal geometry of a 3d object and gives you only the external shell. this cut the polygons and make the object better for 3dprinting. netfabb make something similar when you repair (it closes holes and remove SMALL internal objects).

internal object as far as I know doesn't prevnt you from printing but made the 3d slicing operation really not clean in particular th infill section.
