What You'll Learn
Using the curve tool
The curve tool in Paint Tool SAI simplifies the process of drawing curved lines on pictures in an image editor. To use the curve tool, first, click on SAI's "File" heading and select "Open" from the file menu. Using the file explorer window, select an image to import into SAI and click "Open".
Next, click on the "Layer" heading and select the "New Linework Layer" option from the context menu. Choose a color for your curve by clicking on the desired color in SAI's color palette.
Now, you can access the curve tool by clicking on the little icon with a pen on it in the toolbox. Right-click on the area in your image where you want your curve to start. Click again to place the curve's peak or valley, and a third time to set the curve's endpoint. You can continue adding peaks and valleys by clicking in new locations on the image.
To undo the last addition, click the left button of your mouse. Double-click the right button to anchor your curve.
You can also modify the line weight to create a taper or thickening effect on the lines. It is best to use this tool on a vector layer so you can edit the points even after finishing the curve.

Drawing straight lines
To draw straight lines in Paint Tool SAI, you can use the linework layer tool. This tool allows you to draw straight lines and curves and modify the line colour by clicking on strokes. You can also use the control point tool in combination with the Ctrl/Shift/Alt keys to edit and modify each stroke shape.
To draw straight lines without the linework layer, simply press Shift while using the brush and click. This will allow you to draw straight lines without having to use the linework layer tool.
Additionally, when drawing with a Wacom Bamboo Pad on Windows 10, you may encounter an issue where straight lines start to become circular. To resolve this, disable certain settings by searching for "flicks" in the Start menu and turning them off. Go to the pen options tab and disable single-tap, double-tap, and press and hold by selecting them and adjusting the settings. You can also search for "Wacom tablet properties" in the Start menu to access these settings.
While Paint Tool SAI does offer some capabilities for drawing and editing straight lines, it may be worth considering similar tools in other software such as Clip Studio Paint, Manga Studio, Photoshop, or Sketchbook Pro, which offer more options for creating and manipulating curves and straight lines.

Editing curves
Paint Tool SAI has a curve tool that simplifies the process of drawing curved lines on pictures in an image editor. To access the curve tool, click on the "Layer" heading and select the "New Linework Layer" option in the context menu. You can also access it by clicking on the little icon with a pen on it, found where your layers are.
Once you have activated the tool, you can modify and edit your curves. To do this, you must first select a size preset for your curve from the options in the box below the "Advanced Settings" heading. Then, right-click on the area in your image where you want your curve to start. Click again to place the curve's peak or valley, and a third time to set the endpoint. You can continue adding as many peaks and valleys as you like by clicking in new locations on the image. You can also undo the last addition by clicking the left mouse button.
Double-click the right mouse button to anchor your curve. You can also edit the 'line weight' so that you get a taper/thickening effect on those lines. To do this, hold down the first point you clicked, and drag it to make the curve steep or narrow, then click another point to keep the line going.
Remember that this tool only works on a linework layer.

Modifying curves
To modify curves in Paint Tool SAI, you need to use the linework layer. This tool allows you to draw curves and lines, modify line colours, and edit and modify each stroke shape. You can also control the pressure strength by dragging the control point on strokes.
To create a curve, you can use the curve tool to click and drag points to adjust the steepness or narrowness of the curve. You can also use the polyline tool and change its curve mode to either of the bezier types. You can choose from straight, spline, quadratic, or cubic bezier curves.
You can also modify the line weight to create a taper or thickening effect on the lines. This can be done with the Correct Line tool. Additionally, you can change the pen or brush before or after drawing, but it must be registered as a "brush shape" option.
It is important to note that the curve tool only works on vector layers, and you may need to click outside the canvas to end a continuous line.
