Complex 3D curves are curves that require machining motions on all three directions simultaneously. For example the top of a computer mouse is a complex 3D curve. You can create complex 3D curves in the eMachineShop CAD only by approximating shapes using a stair-case approach as in a topographic map as in the example below:
To create a complex 3D shape:
- Use the Line | Contour command and manual adjustments such as by nudging to create the contour lines.
- Set the Z value for each line.
- Consider using Comments to Machinist "Hand sand to remove steps" or "Contour mill to remove steps"
Also see the Revolve capability which allows for complex "turned" curved shapes.
