Creating Dadoes


You may have parts you need to nest that include dadoes.  In order to effectively prevent these dadoes from being assigned an inside profile, an outside profile, or being omitted completely, you must first save the geometry to a specific layer and name the layer Dado. Any open shape that is required inside of the part must be placed on a layer named Dado.


BobNEST supports 3 types of dadoes:


Following is an example of using dadoes in BobNEST.

Dado Setup

Here is a simple rectangle with a width of 5 inches, a height of 5 inches and .25 radii on each corner. There are also two lines on the inside of the rectangle that we will use as Dado geometry.




1.  First a layer named Dado must be created in the Layer-UCS-Post manager. To learn more about creating layers, view the Layers Tab help topic.


2.  Next to add the geometry defining the dado geometry to this layer, the software must be placed into selection mode, and select the 2 lines shown in green.  Then a simple right click in the CAD window allows the user to choose Modify Attributes and choose Layer.


3.  A dialog will be shown displaying the current layers in the drawing.  Choose the Dado layer and click OK to move the geometry to the Dado layer.


NOTE: All dado geometry, no matter their depths or orientation, that are intended to be cut during nesting need to be placed on the Dado layer.  BobCAD-CAM is not case sensitive so do not be concerned on matching the exact format of the term Dado shown above.  (ie. DADO, dado, dAdO are all acceptable for the Dado layer name).  Also important to note is that if there is an open geometry chained assigned to the Nesting Feature, and it is not located on the dado layer, it will be ignored.


4.  Now when selecting geometry for the Nesting Feature, all of the geometry placed on the Dado layer will be recognized as dadoes, and a Default Dado operation will be added.  A dado operation is simply a Profile Feature, with the default offset strategy set to None for center line cutting.
