Overview & background
The measurement tools are located in the main markup toolbar available when you open up one of your plans. These measurement tools allow you to calibrate distance, indicate length, and record surface area directly onto your plans.
If your plans have a scale printed on them, our software will automatically read that scale and calibrate the drawings for you. This only works if the scale is text/vector-based.
To confirm if the OCR software was able to recognize and calibrate the plan sheet scale, click the Measurement icon and you will see options for the Distance and Area tools.
If these are not displayed, then the plan sheet scale will need to be calibrated.
Use this tool to create the first length measurement and determine the standard scale for the distance on your plan. The symbol for this tool is a question mark between the two opposing arrows. Until you calibrate your plan, this will be the only tool you see in this menu (once you calibrate a measurement for that plan, you can use the other measurement tools).
When calibrating distance, click once on the plan and drag the line across it until you’ve reached the desired length. Click again to finish, and you’ll see a window appear where you can input the distance in feet/inches or meters. Once you’ve saved that measurement, every distance measurement you add afterwards will be automatically determined based on that initial calibration.
Tip: On the web, holding down the "Shift" key while using the measurement tools will snap the line in precise degrees so you can create measurements at specific angles.
Note: If you change the scale of your plan, then all of the existing measurements will be adjusted to match the scale.
Calibrate the scale of multiple plans at once
To do this on web, select the checkbox that appears on the thumbnail for each plan you would like to scale. If you would like to select the whole set, just click the checkbox next to the plan folder.
Once your plans are selected, click on the red "Actions" button at the top of the main Plans page and select "Edit Scale." You can then input the scale ratio that you want the plans to have:
Use this tool to leave distance measurements directly on your plans. The length is automatically calculated based on the initial measurement made with the calibration tool. The symbol for this tool is a ruler.
Use this tool to measure the area within a shape. The symbol for this tool is a filled-in polygon. When you select this tool, first click on your plan and move the line that appears along the edge of the area you wish to measure; each time you click, a new point will be made in the shape.
You must have a minimum of three points in your shape to determine the area measurement, but you can have as many points as necessary to encompass the desired area. Double click to finish creating the shape. The measurement will automatically appear in the center of the shape.
Change units of measurement
You can change the units of measurement used for these tools by going to the 'Settings' page of any project. You will find a “Measurement” section where you can choose between “US/Imperial” (Feet and Inches) or “Metric/SI” (Meters). This will affect all the measurements that you previously made and all future ones you make on your plans.
