As a beginner in CAD, when using the Haochen CAD software to create drawings, I often encounter various issues related to the operation of this CAD software, and am unable to resolve them successfully. Therefore, the editor and experienced professionals from design firms have compiled answers to these common questions encountered by beginners in CAD drawing, creating this comprehensive guide full of useful tips for those just starting out with CAD drawing! 1. How to add a CAD toolbar? Select the View tab, click on Toolbars in the user interface, choose GCAD (Haicheng CAD), and check the desired toolbar. 2. What to do if the toolbar is missing? (1) Select [Options] from the [Tools] menu, or type OP directly in the command line, and then use the [Reset] button under the [Configuration] tab. (2) Enter MENULOAD in the command line, then click Browse and select GCAD.cuix to load it. 3. How to display a coordinate box in the drawing area? You can switch directly using the F6 key, or enter COORDS in the command line to change the system variable to 1 or 2. When the system variable is 0, it means that the coordinate display is updated when a point is specified using a pointing device ； When the system variable is 1 or 2, the coordinate display can be updated continuously. 4. What should I do if the middle scroll wheel of the mouse isn’t working? When using the mouse wheel, users should pay attention to the middle button setting command mbuttonpan. In particular, some users install certain mouse drivers, which causes the mouse wheel to stop working ； The initial value is 1; panning is supported when the button or slider is held and dragged ； When its value is set to 0, it supports the actions defined in menu (.mnu) files. 5. How to set up the auto-save feature? Step 1: In the option settings interface, settings can be made directly under Open and Save ； Step 2: Set the variable SAVETIME to a smaller value, such as 10 (minutes). The default saving time for HaoChen CAD is 90 minutes. 6. How to recover CAD drawings from backup files? First, to make the file show its extension (open My Computer, go to the Tools tab, select Folder Options, then the View tab, and uncheck the box for \"Hide extensions for known file types\") ； Secondly, show all files (in the [Hidden files and folders] selection list, choose [Show hidden files]) ； Find the backup file, which is located on the 【File】tab of the HaoChen CAD options, and rename it in .DWG format. 7. How to close *BAK files in CAD? Method 1: Select the [Tools] menu, open the [Open and Save] tab, and uncheck the box for [Create a backup copy each time it is saved]. Method 2: You can also use the ISAVEBAK command to set the system variable ISAVEBAK to 0; this way, no [*BAK] backup file will be created when saving. 8. What to do if consecutive selections are invalid? To execute the OP (Options) command, go to the Selection tab and uncheck the box for \"Add to selection with SHIFT key\"; once this box is unchecked, adding items to the selection will work as intended. 9. What is the method for setting file security protection? Method 1: Right-click on an empty area in the CAD workspace to bring up the shortcut menu, select the [Options] command, then click the [Security Options] button on the [Open and Save] tab. We can enter a password in the text box to set it. Method 2: When saving a file, it is possible to enable encryption settings for the software.
