The mirror and pattern tools in the Sketch > Create panel let you create identical patterns of sketch geometry or construction geometry in an active sketch in Fusion.
You can use the following commands to create patterns in an active sketch:
The Mirror command 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. A Symmetry constraint is added to the geometry.
The Rectangular Pattern command creates copies in one or 2 directions that you select.
The result is a series of identical copies arranged evenly in rows and columns.
You can also suppress individual copies within the pattern.
The Circular Pattern command creates copies around a center point that you select.
The result is a series of identical copies arranged evenly around a common center point.
You can also suppress individual copies within the pattern.
