Alright, let's get started! First, grab the Pen Tool from the Figma toolbar or just press `P` on your keyboard. The icon looks like a classic pen nib. Click on the canvas to drop your first anchor point. Each click after that adds another point to your shape. - For straight lines, just click to add each new anchor point and move your cursor without dragging. - For curved lines, click to add an anchor point and drag the mouse to adjust the direction handles before letting go. To close your shape, click back on the first anchor point you made. You'll see a small circle icon next to the Pen Tool when you're hovering over that initial point, showing that the shape will close. Use the “Direct Selection Tool” by pressing `V`. This lets you select and drag individual anchor points or direction handles to tweak your shape. Hold `Shift` while dragging to keep angles constrained. - To add an anchor point, hover over a segment of your shape's path and click when the Pen Tool shows a "+" sign. - To remove an anchor point, click on an existing anchor point when the Pen Tool shows a "-" sign. Select an anchor point and press `Shift + C` to switch between a sharp corner point and a smooth curved point. Check out the Control Panel at the top to customize stroke properties like color, thickness, and style, as well as fill options for your shape. Combine, subtract, intersect, or exclude your custom shape with other shapes using Boolean operations in the right-hand panel for more complex designs. Once you're happy with your custom shape, save your work. To export, select the shape, right-click, and choose 'Export'. Pick the format you need (PNG, SVG, etc.) for your project.
