The Review page has tools to calculate distances, areas, angles, and radii but before using them EPR requires the user to calibrate the page by setting at least one measurement scale.

Calibrate

The Calibrate Tool lets users set one or more scales using known distances on the current page. The set scale is then used for any calculations made using EPR’s measurement tools.

Setting a Scale

To set a scale:

1. Click on the Calibrate Tool ( ) button in the toolbar.

2. Move your mouse cursor to the endpoint where you want to begin measuring from and click once.

3. Move your cursor to the other endpoint of the known distance and again click once.

4. In the “Calibration Scale” pop-up that appears:

   1. Select a scale from the “Save As” drop-down list.

      1. If you want your calibration to apply to the entire document, select “Document-wide Scale.”

      2. If you want your calibration to only apply to the current page, select “Scale #1” or the next available scale on the list (up to five different individual calibration scales can be set).

   2. Select a unit of measurement from the “Units” drop-down.

   3. Input the values for the distance you measured.

   4. Click SET to save your calibration (or CANCEL to start over).

Open

Using Calibrations

If a single calibration scale is set, EPR will automatically use that scale as the default for all measurement tools. However, if more than one scale has been set, a pop-up will prompt the user to select one of the calibrated scales from a drop-down before using the selected measurement tool.

Open

Once a calibration scale has been set, a measurement label can also be toggled on to display for any existing sketch. To display the measurement:

1. Click on the Move, Pan, and Select Tool ( ) in the toolbar.

2. Click (or double-click) on the sketch until you see it framed with a red dashed outline.

3. In the Markup Detail window, toggle the Measurement Label to display.

4. Click SAVE MARKUPS at the top of the review page to confirm.

Editing Calibrations

Stored calibration scales can be updated at any time by measuring another known distance (or remeasuring a known distance) and selecting the scale to be updated within the “Calibration Scale” pop-up.

When you click SET to confirm the update, a warning message will pop-up, asking you to confirm the overwrite. Click CONFIRM to save the change (this will update the calculations for any measurements currently using this scale) or CANCEL to stop from overwriting the scale.

Calculate Distance

Once you have set a calibration for a sheet, you can calculate the overall distance between two or more points using the Distance Tool.

Linear Distances

To measure a linear distance:

1. Click on the Distance Tool ( ) button in the toolbar.

2. Move your mouse cursor to the endpoint where you want to begin measuring from and click once.

3. Move your cursor to the other endpoint and double-click. The distance measured (based on your selected calibration) will be displayed.

4. Click SAVE MARKUPS at the top of the review page to confirm.

Non-Linear Distances

To measure a distance that is not a straight line (such as a perimeter):

1. Click on the Distance Tool ( ) button in the toolbar.

2. Move your mouse cursor to the endpoint where you want to begin measuring from and click once.

3. Move your cursor to the next endpoint and just click once. Continue moving your cursor in any direction, as needed.

4. Repeat step 3 as many times as needed.

5. When you reach the final endpoint, double-click. The distance measured (based on your selected calibration) will be displayed.

6. Click SAVE MARKUPS at the top of the review page to confirm.

Editing Distance

You can edit the position of your endpoints or even switch scales without redrawing your distance sketch.

1. Click on the Move, Pan, and Select Tool ( ) in the toolbar.

2. Click (or double-click) on the measurement you want to update until you see it framed with a red dashed outline.

3. If necessary, move any existing endpoints (which should display as red checkboxes) to a new location by dragging them as desired with your mouse cursor. The distance calculation will update automatically.

4. Alternatively, you can also switch the scale used (if the page has multiple scales set) by going to the Markup Detail window and selecting another scale from the dropdown. The calculation will update automatically.

5. Click SAVE MARKUPS at the top of the review page to confirm.

Deleting Distance

To delete a distance measurement:

1. Click on the Move, Pan, and Select Tool ( ) in the toolbar.

2. Click (or double-click) on the measurement you want to delete until you see it framed with a red dashed outline.

3. Then, either:

   1. Click the delete key on your keyboard, or

   2. In the Markup Detail window, click on Delete ( ).

4. Click SAVE MARKUPS at the top of the review page to confirm the deletion.

Calculate Area

Once you have set a calibration for a sheet, you can calculate areas using the Area Tool.

To calculate an area:

1. Click on the Area Tool ( ) button in the toolbar.

2. In the “Calculate an Area” pop-up that appears:

   1. Choose a scale from the drop-down menu. One should already be selected by default, but if the page has multiple scales you can switch to another.

   2. Choose whether to draw With a Guideline or Without a Guideline.

   3. Click APPLY.

3. Move your cursor to the endpoint where you want to begin measuring from and click once.

4. Move your cursor to the next endpoint and just click once. Continue moving your cursor in any direction, as needed.

5. Repeat step 4 as many times as needed.

6. When you reach the final endpoint, double-click. The distance measured (based on your selected calibration) will be displayed.

7. Click SAVE MARKUPS at the top of the review page to confirm.

Editing Area

You can move, resize, rotate or switch scales without redrawing your area sketch.

1. Click on the Move, Pan, and Select Tool ( ) in the toolbar.

2. Click (or double-click) on the area you want to update until you see it framed with a red dashed outline.

3. In edit mode, you can:

   1. Hold the sketch and drag it to a new location.

   2. Click on the red frame to resize and/or stretch the area sketch. The area will update automatically.

   3. Click on the red circle on the lower right of the frame to rotate the object within the frame.

4. Alternatively, you can also switch the scale used (if the page has multiple scales set) by going to the Markup Detail window and selecting another scale from the dropdown. The area updates automatically.

Measurement Summaries in the Markups Panel

The Markup Panel (located on the right side of the Review page) has a Measurements Pane which shows the sum total Distance and Area calculations for the current page, broken down by each calibration scale. It also lists measurement totals using the document-wide scale.

To view the Measurements Pane, make sure the markup panel is visible (click to expand it if collapsed), then click on Toggle Show Measurements ( ).

From there you can click to switch between SUMMARY, DISTANCE, and AREA.
