You're looking for a way to make your idea a reality. You can hire a designer to design and model it for you, but maybe you're on a budget or want to learn a new skill. We at Portland CNC are boot-strappers ourselves and have learned many ways to get something done cost-effectively.

To start, you'll need to make a drawing or model of what you need to have made. Look below at the Software section to choose what's best for you and your project. You might also need a way of accurately measuring your parts, for that check out the Tools section.

Do you need 2D or 3D files?
- 2D - Many projects only need a 2D or vector drawing. The format of choice is a DXF file (drawing exchange file) that is ubiquitous between file systems and most software. DXF files are 2D and have limitations but are good for most projects. DWG is another good format to use in this case.
- 3D - If you need a 3D object, you'll need to design and then export it
- Unsure? Pick a software that does 3D and you'll most likely be able to export 2D from it.
Create your model / drawing and export in:
- 2D: DXF
- 3D files: 3DM (if Rhino), IDES, or STEP
