I'm still trying to create this double DIN adapter. Since it is much too expensive I'm trying to make it hollow. A file says a thousand words.

I get the following error message:

Quote:

We could not determine the size and/or volume of your model due to an invalid model structure. Please investigate the problem and try again.

I guess the walls are too thin. But my software says they are more than 2mm everywhere. I'd absolutely appreciate it if someone could investigate this issue... again.

Thanks!

An upload in WRL format by the way results in the same message. I haven't tried any other format so far.

In C4D my default unit is millimeter, so I think I have to choose the same unit in the Shapeways upload dialog. I don't want to get an object that is 25.4 times the size that it's actually supposed to have.

Just so you know, your hollow section is going to be full of build powder with no way to get it out unless you drill a hole into it.

Please have a look at the picture I have attached. As you can see the holes in the bottom are open. I've also checked the inside of the holes. There is no face covering the holes.]]> SeveQ 2009-09-03T12:41:25-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=6254&th=1317#msg_6254 SeveQ 2009-09-03T13:32:46-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=6326&th=1317#msg_6326
I just uploaded your STL file with size unit mm and everything went fine. I also manually checked the model and it's all perfectly manifold, normals oriented fine etc.

So I'm not sure what the problem is?

Well then, I'd say, consider this issue solved. Thanks for your help though.]]> SeveQ 2009-09-08T18:30:09-00:00
