| nodes and rods (network) structure [message #45910] Sat, 24 March 2012 12:20 UTC |

Hi,
I am very new to 3D prototyping. Unfortunately, I am starting with a quite complex model (got no other choice). I have lots of questions.
My model is a network structure; geometry is composed of very simple elements, that is nodes (spheres) and rods (extrusions of circles). What varies is the orientation of these elements in space. I model in vectorworks, that exports to STL.
I tried many times to upload to shapeways, but had no luck. Since all elements of the structure remained separated, I thought that making a boolean union of the whole would be a good thing. I mean, joining solids avoids non-manifold geometry, correct?
I only partially succeeded because I ended up with three solids. Vectorworks refuses to join those three. Can someone suggest another software to make the union?
Also, when I export to STL and check in netfabb, I don't get only three shells, as I expected. I get MANY MANY of them... how is that explained?

I've divided the structure into a few modules, isolating the parts that repeat. Shapeways upload system still responds that "Only manifold objects can be printed".
Can anyone help me understand what the problem is?
I attach the module I am currently working on.

Is it me, or attachment doesn't work?

Hello stonysmith and jacant,
thank you very much for your help.
@stonysmith: I performed the 'default repair" as you said, and once it finishes and the repaired piece replaces the old one, the big " ! " on the lower right corner disappears so I assume all problems are solved, which is not because i still get an error when I upload to shapeways...
@jacant: I am more than willing to send you my file if you think you can help. I exported to DWG. Strange thing is that when I open this file with autocad 2012 for mac, the geometry appears corrupted, while opening in rhino it looks fine.
Anyway, if you give me your email address, I will send the file to you.
Again, thank you guys for support! it is truly appreciated

What error are you getting when you upload the model (after repair).

If you fixed this in Netfabb, and it still got rejected it could be that it is a big model. There are different rules for 'big parts'
http://www.shapeways.com/design-rules/wsf_bigparts
As can be seen your minimum wall thickness will need to be 1.92mm.

My email address is under this last line.
