You can set a precise line length in Concepts using the Measure feature. It works when drawing live with a tool set to 100% smoothing or by setting a length on the Line Guide before you draw.
Measure with 100% Line Smoothing
- Select a tool on the tool wheel
 - Tap the smoothing icon and slide it to 100%. This allows you to draw instant straight lines.
 - Open the Precision menu and tap Measure to activate it.
 - As you draw, a live measurement tag will show the stroke’s length based on your drawing's scale.
 
Measure with the Line Guide
- Open the Precision menu and tap Guide. Select the Line Guide from the guide options.
 - Enable Measure in the Precision menu.
 - To set an exact length before drawing, Tap+Hold the measurement tag on the guide. Enter your value into the keypad that appears.
 - Pro Tip: Double-tap the crosshairs at the center of the guide to constrain your drawing between the handles. This ensures your line matches the length you set.
 
Editing an Existing Line's Length
- Select any line on your canvas.
 - Tap the length value (e.g., L:x) in the status bar at the top of the screen.
 - Enter a new value in the keypad to adjust the line’s length. It will either Scale or Stretch the stroke based on your setting in the Selection menu.
