Fast and accurate multi-angle in AutoCAD

I believe my friends know that in the ruler gauge do want to three equal an arbitrary angle is impossible, but with CAD, we can easily put an arbitrary angle of three equal. In fact, with the help of CAD, in theory, we can make arbitrary corners to meet the needs of our work. The following author provides two methods for everyone's reference.

The method of equal angle

As the figure, we want to put arbitrary ∠aob three parts, here the author for the convenience of demonstration, deliberately set Ao=bo.

Input Arc command Arc to do with the O as the center, A, b for the ends of a section of the arc, you should pay attention to the CAD to draw the arc to select the starting point and end point is counterclockwise direction of choice. Of course, you can also use the Draw Circle command to draw a complete circle, and then cut off the ∠aob outside of the spare parts to get this arc.

Presumably everyone has thought of, as long as we find the arc of the three points of AB, and connected to the point O can be divided into three ∠aob. In the CAD command line, enter the number of equal order divide command, and according to the prompts to select the circular arc to be divided into 3.

Look, the arc ab has been divided into three equal, if the point on your machine arc AB is not as obvious as the above figure, then select the Point Style menu in the Format menu and select an obvious point style in the dialog box shown in the following figure.

In order to connect the equal points and points O on the arc ab, to remove the auxiliary arc AB and the auxiliary point, to get the ∠aob of the three dividing lines, the same method can be used to do the n points of any angle, except that the number of parts entered in the Divide command is different.

Feel the above method to add and auxiliary arc and auxiliary points very cumbersome? However, if you want to divide the starting edge of the angle into a 0 degree horizontal line, the array can be exempted from the trouble of the guides.

Second, array angle method

As shown in figure, OB is the horizontal line, let's try it out with the array. Select Side OB, enter array command array, select the ring array in the Array dialog box, and pick the center point O, the array method uses the total number of items and the fill angle.

Everybody, here n the total number of items to be filled in is the total number of n+1 items, click Pick up Fill angle button, pick up the end of ∠aob OA on any point, here I select Endpoint A, click OK button to complete the array command. ∠AOB three halves complete:

The disadvantage of this method is that the starting edge of the ∠AOB must be 0 degree level, in the array after the OA side of two coincident line segment, with the mouse click to delete.
