Finding and Placing Nodes

The Dynamo Library is located on left side of the Screen.

[1] Search:use the library search to find nodes.

[2] Browse: discover nodes in the library categories.

[3] Add Nodes: after you find a node in the library, just hit enter or click on it to place it on the canvas.

Writing Nodes to Build a Set of instructions

[1] Click on the output port of one node, then [2] drag the wire to the input port of another, and click again to connect.

[3] Click on empty spot in the canvas to delete a dashed, unconnected wire.

[4] Deleting Wires: Click on the port at the right end of the wire.Then,drag it away and click on an empty spot in canvas.
