Entering degrees, minutes, and seconds in CAD is a relatively simple operation, but it requires some skill and consideration. This article will introduce in detail the methods and precautions for entering degrees, minutes, and seconds in CAD to help readers better master this skill.
First, the input degree.
Entering degrees in CAD is the most straightforward method. All you need to do is type the "d" command in the command line and press the spacebar to enter the Dimension Style Manager. In the Dimension Style Manager, select the current dimension style, and then click the Modify button. In the Modify Dimension Style dialog box, select the Primary Units tab, change the unit format in the angle dimension to degrees, minutes, seconds, and the accuracy to 0d00'00" and click the OK button. In this way, when entering an angle in CAD, you only need to enter the number of degrees.
2. Enter minutes and seconds.
Entering minutes and seconds in CAD is a bit more complicated, but it can also be done with the Dimension Style Manager. First, enter the "d" command on the command line and press the spacebar to enter the Dimension Style Manager. In the Dimension Style Manager, select the current dimension style, and then click the Modify button. In the Modify Dimension Style dialog box, select the Primary Units tab, change the unit format in the angle dimension to degrees, minutes, seconds, and the accuracy to 0d00'00" and click the OK button.
Next, enter the "mtext" command in the command line and press the spacebar. At this point, the mouse changes into the shape of a text box. Move the mouse to the position where you want to insert minutes and seconds, and then click the left mouse button to create a text box.
Enter "1 2" in the text box to indicate 1 point. Then press the spacebar and enter "30" for 30 seconds. In this way, the minutes and seconds are entered.
Notes:1When entering degrees, minutes, and seconds, you need to enter them in a certain format. For example, enter 30For 5 degrees, you should enter "30d30'", where "d" represents degrees, "'" represents minutes, and "" represents seconds.
2.When you enter an angle, it is entered in degrees by default. If you need to enter in other units, such as radians or percentiles, you can convert them in the corresponding units on the command line. For example, to enter a radian of 015, you can enter "015r”。
3.When designing with CAD, it is recommended to use scientific notation to enter angle values. This makes the representation of the angle value more accurate and easy to read.
4.When entering angle values, it is recommended to use a fixed format for input. This avoids design errors or calculation errors due to formatting errors.
5.When annotating angles, you need to pay attention to the accuracy issue. The accuracy setting should be reasonably adjusted according to the design requirements or actual conditions. If the precision is not set properly, it can lead to errors or misleading labeling results.
6.When designing with CAD, it is advisable to make regular modifications and adjustments to the dimension style. This ensures the accuracy and consistency of the annotation results. At the same time, you can also customize the annotation style according to the actual needs to meet different design needs.
7.When using CAD for design, it is recommended to use shortcut keys or command-line operations to improve work efficiency and accuracy. For example, you can use the shortcut key "d" to quickly enter the dimension style manager to make relevant settings and modifications.
