Exterior Perimeter Scanning

Before you begin your scan using ScanToSketch®, enable Do Not Disturb mode on your device — phone calls or app switching ends the scan. Then, plan your scanning route to optimize scanning time and accuracy. It's best to reserve the longest wall or the wall with the most obstructions as the last wall so that you don't need to walk the length of it.

Check out the animation on the right for an overview of the process. You can also click the animation, or click the play button on the video below to watch the full best practices video.

Once you've planned your route and enabled Do Not Disturb mode, go to your first corner and follow the instructions below to begin using ScanToSketch:

With the report open in TOTAL for Mobile, go to the Sketch PowerView, tap the ScanToSketch icon ( ) in the toolbar at the top, and select Exterior Perimeter.
Raise your device slowly to aim the crosshairs at the corner at an angle that shows both walls, and wait for a steady green dot to appear precisely on the corner. Then, press the green Auto button ( ) to place a corner marker.
If the green dot appears in the wrong location or doesn't appear at all, adjust your position and/or the angle of the device to capture more of the structure's walls. Move the crosshairs slowly to the left and right, up and down, closer and further, and then back to the corner. Pointing the device at the ground or at another corner and back also helps with detecting the corner.
Alternatively, you can manually place a corner point by aiming the crosshairs exactly at the corner and tapping the white Manual button ( ). However, we recommend using the green Auto corner markers whenever possible.

Once you've dropped your first corner marker, repeat step 2 for each additional corner: Point your device toward the ground, move steadily to the next corner, raise and aim the device, and drop another corner marker. It's best to walk in a straight line, but it's okay to walk around obstacles.
If you make a mistake or place a corner marker in the wrong location, press the Undo button ( ) to remove it and try again.
Once you've dropped a corner marker at the last corner of the property, press the Done Marking Corners button on the upper right.
Choose whether you want to export your scan as a Closed Area or Unclosed Area, and then press Export To Sketcher to transfer the scan back to your sketch canvas.

That's it! Once you've exported the scan to your sketch canvas, verify the sketch as needed with public records, spot check or remeasure difficult areas, and then edit, stitch, and merge the elements of your sketch to fine‑tune it as necessary.
