Translations:CAM ToolShape/9/en
- Create a new FreeCAD document.
- Open the PartDesign Workbench.
- Create a Body and give the Body a label you want to show up in the bit selection.
- Create a Sketch on the XZ plane and draw half the profile of the bit.
- Constrain the bottom most center of the bit on the origin
(0,0)
. This will be the center of the axis on which the G-code will rotate the bit.- Note: Do not add dimensional constraints at this time.
- Close the Sketch.
- Revolve the Sketch around the vertical Sketch axis.
- Open the CAM Workbench.
- Select the Sketch in the Tree view. This ensures that the PropertyBag created in the next step will be nested in the Body.
- Select the CAM → Utils → PropertyBag option from the menu.
- A PropertyBag named
Attributes
is created. This PropertyBag will be used to control the dimensions in the Sketch. - Double-click the PropertyBag in the Tree view.
- The Property Bag task panel opens.
- Click the Add... button.
- The Create Property dialog opens.
- Create a property named
Diameter
. This property is mandatory for ToolBits. Property names are case-sensitive and may not contain spaces. - Select
Shape
from the Group dropdown list. - Select the appropriate Type.
- Optionally specify a ToolTip.
- Click the OK button.
- In the Property Bag task panel enter a value for the Diameter property.
- Similarly add all other required properties.
- Click the OK button in the Property Bag task panel when done.
- Double-click the Sketch in the Tree view.
- Add dimensional constraints and apply the properties from the created PropertyBag. For example to apply the Diameter property:
- Repeat this until the Sketch is fully constrained.
- Save the FCStd file where FreeCAD expects to find ToolBit files. See Description above.
