Snapping and ruler basics

Snap ON/OFF

Use Snap when drawing with a pen according to the shape of the ruler you created or according to certain conditions.

Select ON/OFF from the menu \ [View] → \ [Ruler/Special Ruler/Snap to Grid]. You can also switch snap selection and ON/OFF from the command bar at the top of the screen.

[POINT]

Ruler tools are classified into [Ruler] and [Special ruler].

[Ruler]: Straight ruler/Curved ruler/Figure ruler/Ruler pen

→ A ruler that allows you to draw by snapping to trace the shape of the ruler you created.

[Special ruler]: Special ruler/Guide/Perspective ruler/Symmetrical ruler

→ A ruler that allows you to snap according to conditions such as converging lines, streamlines, and perspective.

 

Note that snap switching is also set differently for [Ruler] and [Special ruler].

Ruler display range

After creating a ruler, a ruler icon will appear on the layer list.

 

Click [Ruler display range settings] to change the range in which the ruler can be displayed from

 

• Show on all layers

• Show in the same folder

• Show only when editing

 

 

---

Move/duplicate rulers between layers

You can move all rulers on a layer to another layer by dragging and dropping the ruler icon.

You can duplicate all rulers on a layer by holding down [alt/command] and dragging and dropping the ruler icon.

Special rulers/grids

Special rulers are used for drawing effect lines in manga, etc.

You can also snap to the grid (square lines) that can be displayed by selecting Menu [View] → [Grid].

Example of drawing using a ruler

Draw a straight line at any angle with a parallel ruler

The parallel line ruler is a ruler that allows you to draw parallel straight lines at any position on the canvas at a set angle. By taking advantage of this feature, you can use it as a ruler to quickly draw straight lines at various angles.

With the [Object] tool selected, go to Tool Properties[Operation on transparent areas] and set [Parallel line ruler direction specification] to ON. Now you can change the angle of the parallel line ruler by dragging.

 

Drawing with the brush tool...

① The tool switches to the [Object] tool only while you hold down the [ctrl/cpommand] key, so you can drag to adjust the angle of the parallel line ruler

② Release the [ctrl/cpommand] key and use the parallel line ruler to draw a straight line

Repeat this process to quickly draw a straight line at the required angle.

Draw streamlined shapes with curved rulers (splines)

This is an example of creating a ruler that draws mechanical, streamlined curves.

Let's try using the [Spline] setting in the [Curve] setting in the [Tool Properties] of the [Curved ruler], as it is relatively easy to use.

Roughly line up the curve and click on the points that will become the curve. Finally, press [Enter] or double-click to confirm the ruler.

For larger curves, it is easier to place the points farther apart, and for finer curves, it is easier to place the points closer together.

Even if the ruler curve is not what you intended, you can click on the ruler with the [Object] tool after finalizing the ruler to display the points, allowing you to adjust the shape of the curve later.

Ellipse ruler/concentric circle ruler

The ellipse tool and concentric circle ruler are easy to use to draw the tire. Combine various ruler tools to create the desired drawing.

---

Setting the perspective ruler

The perspective ruler is a ruler that snaps to vanishing points set based on perspective projection. Create vanishing points with the [Ruler] tool → [Perspective ruler] sub tool.

The guide lines extending from the vanishing point have two marks displayed: [+] and [〇].

You can adjust the vanishing point position by dragging the [+] mark.

Dragging the [〇] mark will change the angle of the guide line, but the vanishing point will not move.

---

Setting perspective rulers using 3D layers

If you find it difficult to set the vanishing point with the perspective ruler, try using a 3D layer.

Create a 3D layer from the menu [Layer] → [New Layer] → [3D Layer], and adjust the angle with the [Object] tool.

The perspective ruler is set to correspond to the xyz coordinates of the 3D space. Click the ruler icon (which has a red x mark on it by default) on the 3D layer in the layer list to display the ruler.

---

Grid display aligned with perspective

Select the perspective ruler with the [Object] tool and use [Grid] in [Tool Properties] to display a three-dimensional grid.

It can also be used to draw three-dimensional, evenly spaced lines that follow the perspective. Turn on snapping to [Grid] and draw.

You can move the grid position by dragging the icon on the perspective ruler grid. You can also set the grid interval in the tool properties, so combine these to move the grid to the required position.
