53. Ruler: Perspective Array Ruler

From the Perspective Array Ruler in the Ruler tool you can render accurately drawings from a single-point perspective, two-point perspective, and three-point perspective. You can slo combine with the Straight Ruler, Circular Ruler, and Radial Ruler to render backgrounds. Here I have tired to create an apartment block.

From the ① Ruler function select the ② Perspective Array Ruler. The initial number of fractals is set to 3 for each Division, but, apart from the Phase slider, set all ③ Divisions to 1.

Since the cube we are drawing is facing left, selecting the ① Face Selection button under the ruler functions and setting to facing right allows us to cleanly trace the cube we have created.

Return to the Canvas screen and drag the ① Vertex Thumb and ② Face Thumb to determine the size, position and orientation of your cube. When you have arranged your cube to your satisfaction, tap the ③ Lock button.

Open the ① Ruler tooland select the ② Radial Ruler.

Drag the ① Center Thumb to match the vanishing point.

Since it is a two-point perspective, we need to match it to two vanishing points. When we want to add a Radial Ruler, from the ① Ruler Tool we select the ② Radial Ruler. By tapping ③ Add Radial Ruler we are able to match to the second vanishing point.

Drag the ① Center Thumb to match the second vanishing point.

When you have positioned the radial mesh correctly, from the ① Ruler tool select the ② Straight Ruler.

Drag the ① Rotation Thumb and position it vertically.

Along the line of the Perspective Array Ruler we now draw a line using the the ① Radial Ruler.

From the ① Ruler tool select the ② Radial Ruler, and choose ③ Select Radial Ruler.

When you choose the Select Radial Ruler option it will look something like this and so by selecting ① arrow you can switch between the two.

When we have drawn a cube, from the ① Ruler tool we select the ② Perspective Array Ruler and drag the ③ Division Y, Division Z sliders right to determine the number of rooms. This time, we have set Y:5, Z:5.

We will now use the Radial Ruler and Straight Ruler to draw a window in the orange work cell.

This window is duplicated in the grid array, so it is easy to draw many windows.

Next we will draw a veranda. Leaving the work surface as it is, from the ① Ruler toll select the ② Perspective Array Ruler and drag the ③ Phase slider right to -9.0% .

In the orange work cell use the Radial and Straight Ruler to draw a fence.

We will now draw the veranda's fence. Set ① Face Selection button to front face.

From the ① Ruler tool select the ② Perspective Array Ruler and set ③ Phase to -1.0%. Now draw a horizontal fence in the orange work cell.

The Radial Ruler and the Straight Ruler were used to draw the fence.

This is useful when drawing a building using perspective.
