Measurement Operations

Editing Vertices

Add, move, or delete individual vertex points on a measurement to reshape it precisely.

Steps

Select a measurement with the Select tool. Vertex handles appear as small cyan circles.
To move a vertex: drag the handle to a new position. A live preview shows the reshaped measurement while you drag.
To add a vertex: hover over an edge between two vertices. A "+" ghost vertex appears. Press and drag it to insert and place the new point in one motion (releasing without moving just inserts it).
To delete a vertex: quick-click its handle without moving it. Areas keep at least 3 vertices and linears at least 2, and the ends of a straight line can't be deleted this way.

•A quick click (released within 0.3 seconds without moving) deletes the vertex, and any drag moves it. Pressing and holding without moving does nothing. Right-click (or Ctrl + click on a Mac) never adds, moves, or deletes a vertex.
•You can also press Delete or Backspace while hovering over a vertex to remove it. On a straight two-point line, this deletes the whole line instead.
•Clicking the "+" on a straight line converts it into a multi-point linear.
•Dragging a vertex near the edge of the viewport auto-scrolls the view.
•If adding, moving, or deleting a vertex would make an area's edges cross, nothing changes and you'll see an error message.
