Add Lines and Arrows

The arrow tool lets you add lines and arrows to point to an area, a spot, etc., or make a length markup on the plan drawing. You can easily resize and rotate the element to point to the area to be marked.

Beyond basic annotation, it also functions as a measurement tool for lengths. To view exact dimension, simply hover over the line or check the layer editor on the left.

Background - Linarc's intelligent AI algorithm processes each uploaded plan sheet, automatically detecting and saving the drawing's scale. When you create an arrow or line markup, the system uses this scale to instantly calculate and save its dimension. If the auto-generated measurements seem inaccurate, you can easily adjust them. See Recalibrate a Drawing for guidance.

To add a line or an arrow

• Click the down arrow beside the arrow and choose line or arrow depending on the markup you want to make.
• Click the spot on the plan where you want to place the markup and drag it to draw the line/arrow.

• Use the handles at the edges to rotate and/or resize the arrow/line to the required orientation and size.
• Drag the arrow/line to the precise location.

The markup is added with the default red color. 

Customize the Markup

• Click the color palette icon above to the markup or in the toolbar at the bottom to adjust the stroke color. See Format Stroke and Fill Colors for guidance.

You can also clone the markup to mark similar area on a different spot in the drawing. See Clone and Reuse Markups if you need guidance on it.

Every line you add is automatically saved as a new layer within the "Current Markup" group, which is visible in the layer editor on the left side of your screen. From this editor, you can manage your shapes:

• Rename: Click the element's label in the editor to give it a brief, descriptive name to keep your markups organized.
• Lock: Hover over the element and click the icon to prevent accidental edits or deletion.
• Hide/Show: Hover over the element and click theicon to temporarily hide or show the layer on your plan.
• Delete: Hover over the element and click theicon to remove a mistake.

You can continue selecting tools to add more markup elements as needed. Once you are finished annotating the plan, you must save the layer group. See Publish Markups for detailed instructions on finalizing your work.
