You need an editor like MakerWare. Unless you want to print them on a 3D printer through EZ-Robots. What are you trying to do? ARC opens ARC Program files named *.ezb.

my 2 cents.

hi i just wanted to see how it looks.i dont have an printer or makerware.

thank you moviemaker

sorry forgot

thank you moviemaker

you don't need any other programs, ARC can view STL files just fine.

You are opening it incorrectly though...

1. Click on Project in the Ribbon
2. Click on Bit Builder
3. Click on Design
4. Click on Add STL
5. Select the STL and click Open

there's nothing in there.

Look across the top of that dialogue, it has a path to where the STL files should be, this is where you need to put the STL files if you don't want to browse through the hard drive to find them (the column on the left, double click the .. in it to go up a directory and browse through your hard drive).

The default location is usually Documents\EZ-Builder\My STL Files

thank you guys

i found it.i had to schare the stl folder ,too let it chown in ARC.

thank you moviemaker and rich

rich where do you get nieks part?found it.

When I want to look at an STL file. I just double click it and it opens up into MakerWare.

do you need 64bit win7 for to use makerware?
