Floor Elevation is currently available in beta. Workflows, availability, and outputs may change between releases as the feature is refined.

Overview

This is a step-by-step guide for setting up your FieldPrinter and recording elevation data on a real jobsite.

What to Bring to the Jobsite

• FieldPrinter 2
• AT500 Laser Tracker (Hexagon) or AT930 Laser Tracker (Hexagon)
• Tripod
• Reflector
• iPad with Dusty Controller with version 2.14 or later

Setup

1. Verify that the tripod and tracker are in a stable spot, and center the level bubble inside the circle on the laser tracker.
2. On the iPad, open the Setup panel.
3. Toggle Measure Elevation (Beta) on.
4. Follow all steps on the Setup panel until every step has a green check mark.

Note: Completing the Verify Station Location step is required to collect elevation measurements.

Measure Point Elevation

Requires a CSV file with the layer set to measure.

1. Confirm the CSV measurement file is published to the project, and the layer is set to measure. Measurement points are shown in purple on the layout.
2. Complete the Setup process.
3. On the iPad, select the points you want to record. You can queue all of them or pick a subset.
4. Tap Start. The FieldPrinter drives to each point and records the elevation.
5. Watch results come in on the iPad. Each point updates with its measured elevation as the FieldPrinter completes it.
6. If a point can't be reached because of an obstruction, skip it and move on. You can come back to it after restationing.

Measure Area Elevation

The FieldPrinter will autonomously drive through this area to create the area elevation heatmap. The area will be entirely covered, so the edge of some heatmap squares may fall outside of the designated area.

1. Complete the Setup process so that Measure Elevation (Beta) and Background Measure are toggled on.
2. Use the Elevation Area tool on the iPad to draw rectangular areas that mark where area elevation should be collected.
3. Tap Start. The FieldPrinter drives through the area and records elevations as it goes. Outlier readings are filtered automatically.
4. Watch the heatmap fill in on the iPad as the FieldPrinter covers ground.
5. When the queued task completes, look at the heatmap for gaps. Use the Elevation Area tool or manually drive the FieldPrinter through any uncovered regions to fill them in.

Heatmap Visibility

The heatmap toggle controls whether you see the live elevation overlay on the iPad as the FieldPrinter measures. Data is recorded either way; the toggle only controls what's displayed.

1. Open the Settings tab on the iPad or look at the lower right-hand corner of the canvas.
2. Tap to toggle the heatmap display on. Color values appear over the layout, scaled to the min and max readings collected so far.
3. As more data comes in, the color scale auto-adjusts. High spots and low spots stand out at a glance.
4. Toggle the heatmap display off to see the layout without the overlay.

Restationing

Most jobs span more than one stationing. The cloud stitches your data together only if each station shares at least one control point with any previous station.

1. Pick your next tracker location so that at least one of those control points is still in line of sight from the new spot.
2. Scan at least one control point that says Previously Stationed.
3. Rescan at least one control point you used in the previous station. Two or three is even better.
4. Record as many control points as possible, so that there are more options for following stations.

If the iPad warns you that your new stationing does not share control points with a previous one, stop and add an overlapping point before you keep measuring. Ignoring that warning is the most common cause of a disjointed final heatmap.

For very large sites where no single control point is visible from both stations, print and then record new control points during the first stationing in spots that will be visible from the next one. Reuse those during the next station.
