I have access to Maya, Blender, Mudbox, Meshlab, Netfabb, and Zbrush. If you can think of a way to do this on any of those programs or any combination, I'd love to hear it.]]> canadian90 2013-06-18T21:35:49-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=70052&th=14101#msg_70052

Which software do you use for modeling?

can you share that STL file with us?

Thanks!

The original 3ds file I opened in blender has the openings for the buttons while the new download that I posted the URL to does not.

Is there a bumper AND a plain case available?]]> Rayrod72 2013-06-14T14:41:04-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=69811&th=14698#msg_69811
What I had been doing to create the cone was I would draw a right triangle and then use Revolved Boss/Base to make the cone shape. This lead to an STL that appeared to have polygone lines on it (see example above).

However if I created the cone by drawing a circle and using Extrude Bose/Base with a Draft (bringing it to a point) the STL appears smooth.

Upon further investigation I discovered that the STL created with the Extrude tool had exactly twice as many triangles (2876 vs 1438).

Obviously I have NO idea why this is, but there ya go.]]> justice91423 2013-06-14T09:10:37-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=69800&th=14698#msg_69800
Just in case : http://www.shapeways.com/blog/archives/1550-how-to-prep-and- upload-a-3d-model-with-solidworks-for-3d-printing-with-shape ways.html

I know in CATIA we have the same problem and it is necessary to really change the resolution of your part in the software but even with that you still don't have perfectly smooth surfaces.

I imported the .3ds file into blender 2.67 and checked the scale. In blender the length of the case is roughly 4.5 meters when in reality it is 115 mm.[/quote]
The file is a .stl ... I would re-import it.

I downloaded the shapeways basic iPhone case to design my own. The file is found here: http://www.shapeways.com/model/559554/basic-iphone-case-fram e-downloadable.html?li=productBox-search

I imported the .3ds file into blender 2.67 and checked the scale. In blender the length of the case is roughly 4.5 meters when in reality it is 115 mm.

I want to make sure my designs are not too small (less than .02 mm) so I need to be careful with the sizes in my design in blender. i know I can use a ratio to determine the correct sizes but do I need to scale it down to actual size before uploading to print anyways? Is there a quick and effective way of doing this?

Before I found this file I started from scratch and I was using the dimensions Apple posted on their website. I was able to make a correctly scaled model this way.

I had hoped the shapeways case would already be to scale. Is it an effect from importing into blender?

Thank you!]]> Rayrod72 2013-06-14T03:00:02-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=69784&th=14750#msg_69784
1.5 * 25.4 = 38

Your software is exporting the model in metric units, even though it may be reporting inches onscreen.

Using Autodesk Inventor, I created a small 1.5 inch cube, which I exported as a .CTL and uploaded to this site. The cube was a test intended to verify that this service would work, before actually investing time to make a useful model. The cube showed up fine, except the scale was off. 1.5 inches turned into 3.8. Is this a known/common issue? What can I do to fix this?

Thank you for your assistance! I'm looking forward to making awesome things.

Generally, the CTE is important which is rather large for most plastics. Maybe the alu filled nylon might work? Just wondering if anyone has experience with this.

Thanks so much for your help. I'm currently using Solidwoks 2013 SP0, but I was using 2010 when I originally made the part.

I was not able to find the exact options you mentioned, but I did find the STL resolution sliders. Solidworks lists them as Deviation and Angle. I turned them both up to the max and saved the file that way.

It was a big improvement, but I can still see lines (image attached).

Is it possible there is a better file type for this?

Thanks again for your help, and input is appreciated.]]> justice91423 2013-06-11T17:02:27-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=69605&th=14698#msg_69605 influence the "subdivision" or "tesselation" of objects.]]> mkroeker 2013-06-11T12:55:15-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=69596&th=14698#msg_69596
I'm using solid works, and my parts have a lot of curved areas. I found that when I received my parts from Shapeways, the polygons were visible in the part. The attached photo shows the problem.

Do I need to use more polygons somehow? If so, where in Solidworks would I control that?

I'm really as a loss so any help is greatly appreciated.

Thanks

PS. I outputted the parts as .STL files, if that maters

sorry about that! We'll review and update this tutorial asap. In the mean time, VRML2 should work just fine.

How do people generally export out of Maya with color for shapeways? I'm going to try vrml2 format.
