"# Sketching: Dynamic sketch plane\n",
"\n",
"The sketch is a lightweight, two-dimensional modeler driven primarily by client-side execution.\n",
"\n",
"At any point, the current state of a sketch can be used for operations such as extruding a body,\n",
"projecting a profile, or imprinting curves.\n",
"\n",
"The sketch is designed as an effective *functional-style* API with all operations receiving 2D configurations.\n",
"\n",
"For easy reuse of sketches across different regions of your design, you can move a sketch around the\n",
"global coordinate system by modifying the plane defining the current sketch location.\n",
"\n",
"This example creates a multi-layer PCB from many extrusions of the same sketch, creating unique\n",
"design bodies for each layer."
