In most CAD software, you can see the [Options] menu, but because many people know less about the functions in the [Options] menu, they can't find some adjustment methods for the default settings. For the convenience of everyone, in the following CAD tutorial, we take Haochen CAD mechanical software as an example to introduce the use of some option functions. First, we click [Tools] - [Options] in the menu bar of Haochen CAD Machinery Software, and open the [File] tab (Figure 1). figure 1 Here, we can adjust the save path of the file, the search path of the graphic file, the search path of the font text, and so on. For example, when we can't find the font file, we can find it by the font file path given below. We then switch to the [Display] tab, and in the lower right corner of the display, you can adjust the color and size of the crosshair (Figure 2). figure 2 The size of the capture mark of the endpoint, midpoint, and center in the drawing can be adjusted by [Automatic capture marker and target frame size] in the [Sketch] tab (Figure 3). image 3 The target frame is a rectangular area that appears after the command is executed. The adjustment of the target frame can improve the accuracy of selecting the physical element when drawing. The following figure compares the effect of adjusting the target frame (see Figure 4). Figure 4 When we switch the tab to the [Select] option, we can adjust the size of the pick box and the size of the grip point - the pick box is the rectangular area at the center of the cross cursor when the command is not executed (see Figure 5). Figure 5 In the [Select Preview] of the Options dialog box, we can control the highlighting of the primitive: when we remove [When no command is activated] (W), we will find that when the command is not executed, when the cross cursor When placed on a primitive, the primitive will not be highlighted. Similarly, when we remove the [command when the command is active (S)], no matter whether we execute the command or not, the cross cursor will not appear when it crosses the primitive.
