Construction lines in 2D PCB are locked by default.

It will show as dashed lines to indicate it is construction geometry.

Then, you create a construction line to use as a mirror line .

Steps Create five circles at specific locations on the construction lines on the front face of the bracket.

The selected sketch geometry mirrors across the Mirror Line and displays in the canvas. Tips The mirror line can be a construction line or a regular line made in a sketch.

The Line tool in the Sketch > Create panel lets you create a connected series of lines and arcs as sketch geometry or construction geometry in an active sketch in Fusion.

The circles, and any construction geometry, constraints, and dimensions that are added to them, display in the canvas. 3-Tangent Circle Create a circle by selecting 3 lines to define the position and size of the circle so that it maintains tangency with the selected sketch geometry.

You used the construction lines of the new sketch to help create a series of circles which you then extruded to make holes in the bracket.

Create a PCB Sketch and draw construction lines . Control sketch visibility from the browser node.

The lines , and any construction geometry, constraints, and dimensions that are added to them, display in the canvas.

You select 3 lines that the circle will be tangent to.

PTH pads provide a more robust construction , but are physically larger than SMD pads.

Mirror The Mirror tool creates a copy of selected sketch curves mirrored across a line in the active sketch. The result is an identical copy mirrored on the opposite side of the line .

Sketch a tuning fork tutorial In this tutorial, you use common sketch entities such as lines , circles and arcs, to create a tuning fork.

Click to end the line . Continue sketching lines as follows: Note: As you place the lines , some constraints are automatically created.
