When you use the Hard Mask or Soft Mask with an active Shape Guide, the erased area may not align perfectly with the guide boundary. This usually happens because the mask responds to the pressure of your stylus, creating a softer edge that does not extend to the maximum boundary.
Here are two ways to get a clean, sharp edge.
Use Your Finger to Erase
Your finger does not have pressure sensitivity. Tracing the guide with your finger will create a solid, clean-edged mask that matches the guide boundary exactly.
Temporarily Disable Pressure
You can turn off pressure response for your stylus.
- Go to the Settings menu.
- Tap the Stylus tab.
- Set the Pressure Response curve to be a flat line at the top of the graph.
