Description

How to make a spatial perspective ruler

technical field

The invention relates to a method for making a professional drawing ruler, in particular to a method for making a space perspective ruler made of hard transparent plastic.

Background technique

In the process of spatial perspective drawing, many people cannot accurately complete the spatial perspective drawing even with the help of drawing rulers and other tools, and it is very troublesome to make. Even if they can really draw the spatial perspective well, it will take a lot of time. It takes practice to get it done. Therefore, under such a background, there is a great need for a tool that does not change the perspective principle, is easy to learn, quick to use, and accurate in drawing, which creates conditions for the appearance of the perspective ruler.

Contents of the invention

The object of the present invention is to provide a method for making a space perspective ruler made of hard transparent plastic.

The invention takes the common drawing ruler as a reference, adds a plurality of auxiliary rulers, and connects the large ruler through the medium of vanishing point positioning and rotating fixed buckle, so as to realize the rotation between the scale ruler and the auxiliary ruler to ensure the accurate depiction of the perspective angle.

The specific steps are:

1. Make an angled perspective ruler, a parallel perspective ruler, a scale, an angled displacement perspective ruler, a scale extension fixing sleeve, a vanishing point positioning and a rotating fixing buckle with hard transparent plastic as a material.

Second, engrave the scale on the scale.

3. Put several scale extension fixed sleeves on the scale, and use the scale to extend the fixed sleeve to adjust the length of the scale to adapt to the needs of paper of different sizes.

4. Install the angled perspective ruler and the angled displacement perspective ruler fixed by the vanishing point positioning and the rotating fixed buckle at both ends of the scale. And it can be rotated at multiple angles, and the angled displacement perspective ruler can move the vanishing point to solve the problem of describing the blind area.

5. Install the parallel perspective ruler fixed by the vanishing point positioning and the rotating fixed buckle in the middle of the scale.

The present invention has the following advantages:

1. Based on the ordinary drawing ruler, a new perspective drawing function has been added.

2. The principle is simple, and it can be used just by rotating, stretching and other actions.

3. Convenient and practical, providing more convenient and accurate drawing tools for the majority of cartographers.

Detailed ways

Example:

The specific steps are:

One, take hard transparent plastic as material to make angular perspective ruler 1, parallel perspective ruler 2, scale 3, angle shift perspective ruler 4, scale extension fixed sleeve 5 and vanishing point positioning and rotation fixing buckle 6.

2. Engrave a scale on the scale 3.

Three, put several scales on the scale 3 to extend the fixed sleeve 5, utilize the scale to extend the fixed sleeve 5 to adjust the length of the scale 3, to adapt to the needs of paper of different sizes.

Four, the two ends of scale ruler 3 are installed by vanishing point positioning and the angled perspective ruler 1 and the angled displacement perspective ruler 4 fixed by rotation fixed buckle 6, the angled displacement perspective ruler 4 is divided into two sections by the vanishing point location and The rotating fixed buckle 6 is connected, and can be rotated at multiple angles, and the angled displacement perspective ruler 4 can move the vanishing point to solve the problem of describing the blind area.

5. Install the parallel perspective ruler 2 fixed by the vanishing point location and the rotation fixing buckle 6 in the middle of the scale ruler 3 .

In angled perspective: first use the vanishing points at both ends of the scale 3 to locate and rotate the fixing buckle 6 to determine the two vanishing points. If you need a higher vanishing point, you can pull the scale 3 to increase its distance. Because of the scale Extend the fixation of the fixing sleeve 5, and the distance of the vanishing point can be doubled. Next, use the angled perspective ruler 1 to easily draw the changing line of the angled perspective. If the line is blocked by the scale 3 when drawing the changing line Enter the blind spot, then use the angular displacement perspective ruler 4 to make the vanishing point correspond to the vanishing point positioning of the angular displacement perspective ruler 4 and the rotation fixing buckle 6, and then draw.

In parallel perspective: first determine the vanishing point on the paper to locate the vanishing point and rotate the fixed buckle 6 to correspond to it, then use the parallel perspective ruler 2 to draw the changing line. All remaining original lines (lines parallel to eye level and lines perpendicular to eye level) in angulated and parallel perspective can be easily completed with scale 3.
