Trim Surfaces - Check to trim the selected surfaces back to the fillet edge.
End Points - Check to digitise the start and end points of the fillet.
The variable radius is defined by the Start Radius and End Radius parameters. Certain limitations apply to the accurate generation of fillets:
The surfaces must not be parallel or nearly parallel at any point along the fillet.
The fillet cannot take place around a tight corner, the radius of which is less than the fillet radius.
Tolerance - Specifies a value to alter the smoothness of the fillet. Smaller tolerances result in smoother fillets but take longer to calculate.
Search Grid Density - EdgeCAM uses a 'search grid' to find the intersection. Usually a density of 2 gives satisfactory results. However, surfaces that overlap in a number of places, or only overlap by a small amount, might need a higher search density. Higher densities take longer to calculate.
Name - Specifies a name for the surface. Use this name later to select the surface.
