fillet
Purpose
fillet
Create circular rounded corners in geometry object.
Syntax
Description
g = fillet(g1,...)
g = fillet(g1,...) creates rounded corners in 2D geometry object.
The function fillet accepts the following property/values:
TABLE 1-43: VALID PROPERTY/VALUE PAIRS
PROPERTY VALUE DEFAULT DESCRIPTION
out
none
Cell array of
strings
Determines the output
point integers | all | all Specifies which vertices are filleted
none
radii 1-by-m vector Curvature radii of the fillet
The corners to fillet is either specified with either the property point or edges. The
default value is the all possible corners are filleted.
If there is only one radius but more than one corner then the single radius is used
for all corners.
Examples
Fillet a rectangle object:
r = rect2;
s1 = fillet(r,'radii',0.1);
s2 = fillet(r,'edges',[1 2;2 3],'radii',0.2);
Diagnostics
If fillet does not succeed in creating a rounded corner according to the specified
radius, the corner is skipped.
When a fillet intersects another edge, the function generates an error message.
Compatibility

The FEMLAB 2.3 property Trim is no longer supported. Only pair of edges that
have a common vertex can be filleted. For edges that are not linear, the linear
approximation of the edge in the corner is used to compute an approximate fillet.
