Add a diagram to a Freeform board on Mac
You can connect shapes and other items with lines to create a diagram or flowchart on your Freeform board.
In the Freeform app
on your Mac, click a category in the sidebar, then double-click a board to open it.If you don’t see the sidebar, choose View > Show Sidebar.
If necessary, click the Show Connectors button
or choose View > Show Connectors. (When connector lines are enabled, the button looks like this 
.)Add any type of item—text, shapes (except lines), photos or videos, links, sticky notes, or other files.
Select the item you added, then drag one of the arrows up, down, left, or right, to add a connector line.
When you stop dragging the connector line, the shapes library appears, and you can select the next shape for your diagram. (Click the More button
to open the full shapes library.)You can also drag a connector line to another item that’s already on the board, and the line is automatically added between the two items.
Repeat steps 4 and 5 until your diagram is complete.
Tip: To quickly duplicate a shape (or other item) and add a connector line, select the shape, then click and hold the connector arrow on the side where you want to add the line and shape—as you hold the arrow, a preview of the shape and line appear, and when you let go, they’re placed on the board.
Continue to build your board by adding text, shapes or lines, photos or videos, links, sticky notes, and other files.
