Blendercam Tools
Blendercam has a number of curve operators that will modify selected curves to make them better suited to CAM operations. They can be found in the Tool Shelf Panel located on the left of the 3D view editor. The operators create new curves which can then be used in CAM operations.

- Curve Boolean
- Intarsion
- Add Overcuts
- Silhouette Offset
- C-Remove Doubles
If the Tool Shelf is not visible on the left of the 3D view then use the short cut T or use the mouse to left button select the small + near the top left border of the 3D view.
- 1 - The 3D view editor must be in object mode. Select the Blender CAM tab to view the Curve CAM Tools panel.
- 2 - Select the expansion arrow to see the tool buttons available.
Perform a Boolean operation on two or more curves. A new curve is created. The Boolean operations that can be performed are:
- Union -
- Difference - subtract the first selected curve(s) from the last selected.
- Intersect -
Makes a new curve that is cuttable from both the inside and outside. This is useful for intarsia, inlays, and joints. All sharp edges are rounded over using the cutter diameter. Works on mesh, text, and curve objects.
Adds overcuts for slots/inserts and creates a new curve. Works on text and curve objects.
Operator Options:
- diameter - tool diameter to use for the overcut
- threshold - the minimum angle that an overcut is applied.
- Outer polygons -
- Invert -
This operator finds the silhouette of objects(meshes, text, curves just get converted) and offsets it and creates a new curve.
Operator Options:
- offset - tool diameter to use for the offset
Curve remove doubles - warning, removes beziers! This operator will convert the curve to a mesh, perform remove doubles on the mesh, and then convert it back to a curve. This can be used to fix curves that are imported into Blender from other applications i.e. stl, dxf, that may have overlapping control points in the curve which can be a problem when calculating an operation.
