subtract

Boolean subtraction operation on two RF PCB shapes

Since R2021b

Syntax

c = subtract(shape1,shape2)

Description

c = subtract(shape1,shape2) subtracts shape1 and shape2 using the subtract operation. You can also use the - symbol to subtract the two shapes.

Subtract Two RF PCB Shapes

Open Live Script

Create and display a cross trace shape.

trace = traceCross;
show(trace)

Figure contains an axes object. The axes object with xlabel x (mm), ylabel y (mm) contains 2 objects of type patch. These objects represent PEC, mytraceCross.

Create and display an annular ring shape with an inner radius of 4 m.

ring = ringAnnular(InnerRadius=4);
show(ring)

Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 2 objects of type patch. These objects represent PEC, myringAnnular.

Subtract the annular ring from the cross trace and display the result.

shapeDiff = subtract(trace,ring);
show(shapeDiff)

Figure contains an axes object. The axes object with xlabel x (mm), ylabel y (mm) contains 2 objects of type patch. These objects represent PEC, mypolygon.

Create and display a curved bend shape.

bend1 = bendCurved;
show(bend1)

Figure contains an axes object. The axes object with xlabel x (mm), ylabel y (mm) contains 2 objects of type patch. These objects represent PEC, myCurvedbend.

Create and display a curved bend shape with a spatial offset.

bend2 = bendCurved(ReferencePoint=[-1e-3 -1e-3]);
show(bend2)

Figure contains an axes object. The axes object with xlabel x (mm), ylabel y (mm) contains 2 objects of type patch. These objects represent PEC, myCurvedbend.

Subtract the offset bend from the default bend and display the result.

shapeDiff = bend1 - bend2;
show(shapeDiff)

Figure contains an axes object. The axes object with xlabel x (mm), ylabel y (mm) contains 2 objects of type patch. These objects represent PEC, mypolygon.
