Learn these drawing skills, instant you are a master!

The following small series for you to bring a professional drawing tools- geometry , whether you are a teacher, or drawing designers, this software you must be worth owning. Words do not say much, the following directly into the topic, one to learn the following drawing skills.

Technique one, draw the heart-shaped line with the geometric artboard

Index: ★

The specific drawing steps are as follows:

1. Create a new parameter. Right-click the plot area, "New parameter", labeled A, the value is 4, the unit "none".

2. Shortcut key "Ctrl+g", bring up to draw new function editor. Point "equation", select polar coordinate equation. The function is clicked in the editor. "OK" to get the heart shape image.

3. Modify the Origin label to a, draw a point on the image, label B, select point B, select "Construct"--"segment". Select point B and Line AB, "construct"--"trajectory". Select the track and the image line, choose Show-color, red. The linetype is changed to a thin line.

4. Right-click Track, "Properties"--"drawing"--"sample Quantity", modified to 1000. Hide points A, B, done.

5. Select parameter A, "edit"--"Action class button"-"animation", adjust the range of a and change the speed. Click on the button, you can also see a beating heart!

Technique two, make fractal tree with geometry artboard

Index: ★★★★★

The specific drawing steps are as follows:

1. In the vertical direction, draw line AB, select Line AB, execute "construct"-"midpoint" command, construct line AB midpoint C.

2. Double-click the B-point to rotate the point C by 120 degrees to the e-point and rotate-120 degrees to D. Construct the segment BD, be.

3. Create a new parameter n=3, then select a, b and parameter n, Shift-click the "deep Iteration" command under the "Transform" menu, and in the popup iteration dialog, map A to b,b map to E, select "Add New Mapping" under the structure, and continue to map A to B,b to D.

4. Change the value of parameter n to see the growth of a fractal tree. For example, change the parameter n value to 10 to get the fractal tree.

Technique three, draw Sierpiński carpet with geometry board

Index: ★★★★

The specific drawing steps are as follows:

1. Open the geometry artboard software, draw the line AB on the plane, and construct the square ABCD with the line AB as the edge length.

2. With point A as the center of Zoom, point B, D scale to 1/3 to get E, F, D as the center of the zoom, point A, C scale to 1/3 to get G, H. The same point I, J, K, L. Connect the points and divide the squares into nine equal portions.

3. Click "Data-New parameter" to create a new parameter N and change the value to 2. Click a, b two points (note: These two points are the two endpoints of the segment you first drew, and the parameter n, hold down the SHIFT key, click "Transform-depth iteration" To open the iteration dialog, select G, p Two, click "Structure"-"Add New Mapping", select P, o Two, continue to add new mappings, Select O, J;f, M;n, K;a, E;e, L;l, B. (Note: The middle of M, n two points do not point) click on "Iteration" to complete the iterative production.

4. Fill in the middle square mnop, measure the area of the MNOP, select the measure result and the filled square, click Show--color--parameters, and click OK in the dialog box that pops up.

5. Finally, select all points and press Ctrl+h to hide unnecessary points.

Warm tip: Change the size of the square ABCD, the color of the square mnop varies with its area. By changing the value of parameter N to observe the difference of Sierpiński carpet.

Read the above article, do you think the geometry is a tall professional drawing software? In fact, it can not only be used to draw geometric figures, but also can be constructed such as the above beautiful pattern, but this is mastered the geometry of the basic operation of the artboard can be done after.
