To create a place or a transition, bring up the Page marking menu by pressing and holding down the right mouse button on the page. See the marking menus page if you are unsure about how to work with marking menus.
Select New Arc to start an arc. An arc will be attached to the cursor, and you can drag it to the transition or place where you want the arc to end. Click on the background to add bend points or on a transition or place to finish the arc. You can also add more bend points later by dragging the arc where you want the bend point to occur.
An arc must go from a place to a transition or from a transition to a place.
You can abort the creation of an arc by applying the Drop Tool tool before you attach the final endpoint.
Select the desired element to create transition, place, or arc:
Click with the left mouse button where you want to create the element.
When creating an arc, you can create bend points by clicking on the page background, just like for marking menus. If you want to cancel the arc, click again on the palette cell where you picked up the arc tool. Alternatively, bring up the Workspace marking menu and select the Drop Tool entry.
