hardness of the brush

The bottom slider controls the hardness of the brush. When using a pencil (lasso pencil), the approximate hardness will be displayed at the top of the slider. It is designed to become softer and darker as you go up.

When using a pen, the higher you go, the smaller the pen pressure size becomes, and the lower you go, the smaller the minimum width of the pen pressure size becomes.

Settings *Details are in a separate section below.

Settings related to the entire app are available from the gear mark. Currently, some optional drawing functions such as snapping are also summarized here.

Setting

Straight Snap Turns on Straight Snap. Enables vertical and horizontal snapping across the screen.

Isometric view This is a function that allows you to snap to vertically and horizontally isometric lines.

Grid Angle You can control the angle of the entire grid. This app's snap does not follow the screen viewing angle, so you can also control the line angle by changing the viewing angle.


Image stabilization You can control image stabilization. There is no clear recommendation, so I think it would be best if you choose the one that is easy to use. If you want a direct feel, set it low, and if you want to play long strokes cleanly, set it high.


Tilt Sensitivity This setting is mainly used to control the angle at which the drawing occurs when the pencil is laid down. The tilt of the screen and pen will vary depending on the size of the user's hands, so be sure to find a value that is comfortable for you. If you increase it, the sensitivity will increase and it will be easier to produce a laid-back image.



Use the Touch to Scrape tool This feature blurs drawn lines by rubbing them with one finger. It was equipped with a function that can be used for drawing. It may interfere with accurate depiction, so please turn it on and off as appropriate.


Place the vertical menu on the right You can place the vertical menu on the left or right depending on your preference. Please use whichever is easier for you, regardless of your dominant hand.

Top menu text display The UI of this app is set up so that the text display can be omitted to make it easier to use even in split view. You can also set the text to be hidden when displaying in full screen.


Clear cache data If you are having problems with display or loading, you may be able to resolve the issue by clearing the cache data. We are working hard to prevent any problems from occurring, but if something happens, please give it a try.
