Using the Perspective Ruler with 3D Layers: Perspective Rulers Part 2



I will explain about the new features of the perspective ruler following on from Part 1.

[1] Using the perspective ruler on a 3D layer

When you create a 3D layer, a perspective ruler is also created.

After dragging and dropping, the perspective ruler will become hidden. You can click on the ruler icon in the 3D layer to make the perspective ruler visible.

Click the 3D material with the [Object] tool to operate the 3D layer.

The perspective works in a 3D space. If you change the angle of the 3D layer, the perspective ruler moves with it.

On the [Tool Property] palette, under the [Camera] section, you can adjust the [Perspective] and [Roll] settings, and the perspective ruler will move appropriately.

On the [Layer] palette, if you unlink the ruler and layer, they will stop moving together. Click again to make the ruler move with the angle of the 3D layer again.

Now if you add a 3D material onto a canvas with a three-point perspective ruler, it will be placed onto the canvas in accordance with the angle of the perspective ruler.


Please read the following article to learn more about operating the camera in a 3D layer.

[2] Editing the perspective ruler on a 3D layer

To directly edit the perspective ruler, go to the 3D layer and click the ruler icon. Then, using the [Object] tool, select and move the perspective ruler.

If you move the vanishing points or change the eye level, the angle of the 3D layer will change too.


When changing the vanishing points and eye level of the perspective ruler, the angle of the 3D layer can sometimes change significantly. The 3D materials may also turn to face a different direction.

If this happens, you can move it back to the right position by moving or rotating the 3D material, or click the 3D material with the [Object] tool to drag and drop it again.

You can add more than four vanishing points to the perspective ruler, but these will not move with the angle of the 3D layer.

You can also delete vanishing points. However, the perspective ruler and 3D layer will only move together if it is a three-point perspective ruler.

If you have deleted the perspective ruler on a 3D layer, you can add a new perspective ruler in the 3D space by going to the [Layer] menu > [Ruler - Frame] > [Create Perspective Ruler].

Drawing example:

In the following example, I placed two 3D drawing figures and adjusted the angle according to a rough sketch, with the perspective ruler visible (the top and left vanishing points are out of frame).

I add a vanishing point for the roof to match my rough sketch. The 3D drawing figures were in the way, so I changed the layer opacity to 0%.

I finish drawing the characters based on the drawing figures.

Have fun trying out the new features of the perspective ruler!
