Concepts uses a dynamic measurement system called Measure instead of a static ruler. Activate it from the Precision menu to apply live, scalable measurements to anything you draw.

Here are two primary ways to measure:

Measure with Line Smoothing

1. Open the Precision menu and toggle Measure to "On".
2. Select a pen and set its Smoothing to 100% on the inner ring of the tool wheel.
3. When you draw, the line will automatically straighten and display a live measurement tag.

Pro Tip: To set a precise length, select a smoothed line and tap and hold its measurement tag to enter a custom value.

Measure with the Line Guide

1. Activate both Measure and the Line Guide from the Precision menu.
2. Position the guide on your canvas. The distance between its handles will display a measurement.
3. To set an exact length, tap and hold the guide's measurement tag and enter a value.
4. Draw along the guide to create a line of that specific length.

Bonus: You can tap a measurement tag to make it "stick" to the canvas as a permanent label.
