How do I convert .STEP files into .obj or .stl files?

I want to be able to convert the .STEP filed I download off GrabCad into a more usable file format for my projects, like .obj or .stl.

You can do that by SolidWorks. It makes me happy to help you. You can send me the STEP file to take a look.

On OS-X at least, read STEP/STP in to the free (open source) CAD Assistant ( and use the floppy disk icon on left to save as ply (w/ colors) or obj (w/ mtl). Also check out the cool "Clipping plane" feature (bottom icon on left).

If you want to colorize first, use FreeCAD and, save as STEP w/ color and follow instructions above.

All free & open source.

You'll need a program that opens the STEP format, and allows for saving/converting in STL or OBJ formats.
Check out Meshlab. I'm pretty sure it is free, and would be able to do the conversion:

I'm glad to see the down vote button is working :)
If Meshlab will not open a STEP file then we should find something that will convert the file into one that Meshlab will open.

Meshlab does some amazing stuff for a free program. Check it out even if it won't help in this instance.
