This is a step-by-step tutorial on generating a toolpath with Blender CAM. For detailed description of panel options go [here](Blendercam-Panel-Descriptions.md).
Choose Parallel (or Outline Fill, Circles, Spiral, Block, Cross) in the Strategy dialog. Waterline option works best when OpenCAMLib is installed and other operations require curve data source. See how to generate curves from mesh model [here](Profile%20and%20Pocket%20operations.md).
In Object dialog select object being source of geometry for toolpath generation.
## Configure Cam Material and position object
In CAM Material size and position, set radius around model option to reflect the amount of stock material to be machined.

Manually position object inside work area, or use "Position object" option to position it automatically.

If the box representing material doesn't update, uncheck "Estimate from model" option and then check it again.
## Configuration of the active Operation
Set "Distance between toolpaths" to desired value.
"Distance along toolpaths" option determines accuracy. Lower values result in more accurate toolpath, but make computation slower and increase amount of resulting G-code.
Select "Use exact mode" - it improves accuracy. If you have [OpenCAMLib](Opencamlib%20Installation.md) installed, also select "UseOpenCAMLib" - it impoves accuracy and speeds up the computing time. OpenCAMLib also enables high quality algorithm from calculating waterline toolpaths.
