What are the methods for making cylinders of geometry artboards?

Many teachers in the teaching process will not only involve graphic graphics, but also involves three-dimensional graphics. A cylinder is a solid geometry, which is the geometry of a curved surface in which the straight side of the rectangle is the axis of rotation and the remaining three sides are rotated 360°. A lot of teachers are using the geometry of the Guide to the tutorial, the following we would like to share with you the geometry of the method of the cylinder is what?

The specific drawing steps are as follows:

Step one draw Ellipse

1. Open the Geometry artboard, click the "Customize Tool" button on the left sidebar and select "Conic a"-ellipse as shown in the popup shortcut options.

Select the Ellipse tool sample under the custom tool

2. After selecting the above tools, click the mouse on the canvas to draw an ellipse and draw a good ellipse as shown.

Example of drawing an ellipse using the Ellipse tool

Step two make cylinder

1. Select the left sidebar "point tool" and draw a dot C above the ellipse. Select the Center and Point C, click the Transform menu in the top menu bar, select the Pan command in its drop-down options, fill in the popup dialog with a distance of 5cm, and click the Pan button.

Example of PANNING commands on center and Point C

2. Select the "Move Arrow Tool" to select the C-point and pan-resulting C ' point, click the "Construct" menu in the top menu bar, and select the "track" command in its drop-down options as shown in.

Select the C, C ' Execute construct track command example

3. This also sees an ellipse on top. Use the Segment tool to construct the segment cc ', select point C and Segment cc ', click the "Construct" menu in the top menu bar, and in its drop-down option select the "track" command, you can see the cylinder as shown in.

Select point C, CC ' construct trajectory to get cylinder example

The above gives you a description of the geometry of the method to do the cylinder, compared to the previous approach, although a little bit more complex, but the use of the trajectory function, we can construct a lot of solid geometry, we may go to try. If you want to learn more, you can focus on the geometry artboard tutorial .
