Add Length Measurements

The ruler tool lets you measure the distance between any two points in feet/inches. Drawings are created at various scales, so it’s essential to calibrate the ruler tool individually for each drawing.

• If the plan sheet includes a clear printed scale, Linarc detects it automatically and auto-calibrates the ruler tool. An indicator appears each time you open the sheet, confirming that the scale has been applied.
• If the sheet does not show a visible scale—or if multiple drawings with different scales appear on the same sheet—the system cannot determine the scale automatically. In such cases, you must complete a one-time manual calibration. 

This article explains how to manually calibrate the measurement tool for a plan sheet and create a length markup. This is useful, for example, to measure the distance between two points and mark the same distance/area on a different location in the drawing.

• Calibrate the Ruler
• Add a Length Markup

Calibrate the Ruler

• Open the plan.
• Identify a location on the drawing with known dimensions, for example, a length marking between two points in the drawing. An example is shown below:

• Select the 'ruler' tool  
• Click on the location of the drawing where you want to place the ruler.
• Click the line to select it.
• Drag the handles at the ends to resize the line to cover the distance of the known dimension.

• Double-click on the line
• Enter the known dimension in the 'Enter the Scale' box in feet/inches. For example, 26'00"
• Click 'Submit' to save the calibration

You can change the color and stroke width of the line using the 'Stroke' tool.

• If you want to add a length markup, continue as explained below
• If you want to just save the calibration, click 'Save Markup'

Add a Length Markup

Prerequisite: You should have calibrated the ruler before adding a length markup.

• Select the 'ruler' tool  
• Click on the location of the drawing where you want to place the length markup.
• Drag the handles at the ends to resize the line and cover the unknown distance.

The line shows the dimension in feet/inches.

You can change the color and stroke width of the line if required.

To move the line with the dimension to a different location, click the line to select and drag it to the required location.

To change the color and stroke width

• Click on the arrow to select it
• Click the 'Stroke' tool
• Choose the color from the palette
  • Alternatively, use the color picker at the bottom right to choose a custom color
• Size - Use the slider to set up the brush width for the markup

Your selection takes effect on the currently selected markup and is auto-saved for your next markup tool.

The markup element is added as a layer to the 'Draft' group. It is shown in the layer editor on the left.

• Use the icon to show or hide the layer
• Click the icon to remove an element added by mistake
• Click the element label in the layer editor and edit it with a brief description of its purpose, if needed, to keep your elements organized
• Go to the next tool if you want to add more markup elements

Once you are done with the markup elements, save the layer group as a markup. See Publish Markups for more
