To delete lines or remove unneeded buildings from your DIY project or Measurement Order, first navigate to the Sketch tab in your project:

Now, click Delete Edge from the toolbar on the right-hand side, or press the D hotkey:
Left click on the lines you'd like to get rid of, and they'll be deleted from the sketch:
If you wish to remove an entire building, click on all of its associated lines on the diagram to remove it from both the square area and linear measurements. Look for the green dots of the line endpoints to make sure you have deleted all necessary lines.
To view these updates to the measurements in your Sketch Report PDF, be sure to generate a fresh PDF when you navigate to the Documents menu.
