The overlapping objects on CAD drawings are so confusing; how can I deal with this? Is there really no way to quickly compare old and new CAD drawings, other than taking partial screenshots or working overtime to add annotations? How are beautiful and diverse layout diagrams created? Whenever beginners in CAD drawing encounter this situation, they always cry out from the bottom of their hearts: \"Why is CAD so difficult?\" It’s really too difficult! ”Next, taking the Haochen CAD software as an example, I’ll share with you some basic tips for getting started with CAD drawing! True passion means fearing no hardships at all! So, what the editor is offering to you today are some advanced CAD tips that provide a one-stop service including \"viewing, comparing, and generating drawings\". Are you ready to give it a try? 1. Controlling the order of overlapping objects: In daily CAD design work, it is common to encounter situations where CAD objects overlap. Especially for equipment and process pipelines in buildings, it is necessary to continuously adjust their relative positions (up and down) according to the design, such as moving yellow pipelines to the upper layer. Method 1: DRAWORDER command – Enter the DRAWORDER command in the command line, then follow the on-screen instructions to select the objects and decide whether to place them at the front or at the back, thereby reordering the CAD objects. Method 2: Drawing display order. If you find CAD commands difficult to remember and the steps complicated, you can simply select the target element, right-click on it, and adjust the drawing display order. Method 3: In the Utility tab of the ribbon, select the Drawing Order function group. First, select the object that needs to be rearranged, then click the move forward or move backward option. 2. Comparison between old and new CAD drawings: “What changes have been made to the new drawings compared to the previous version?” ”This is a problem that various specialties in design institutes often encounter when working together on designs. Using the drawing comparison function in the HaoChen CAD extension toolkit, it is possible to quickly compare CAD drawings from old and new versions. The specific steps are as follows. (1) Activate the drawing comparison function in the HaoChen CAD extension toolbox, or enter CMP directly in the command line ； (2) Select two drawings to be compared, and make the relevant settings as well as specify the display options in the “Comparison Settings” section ； (3) After setting it up, click Compare. On the CAD drawing, the similarities between the old and new versions are displayed in gray, while the differences are highlighted in a predefined color for easy identification. 3. Creating irregular viewports: Creating irregular viewports is an essential skill for layout and drawing, and it is used very frequently when creating detailed enlarged views. In the layout space, first draw a rectangular viewport, and then use the viewport cropping function to create the desired irregular-shaped viewports. Step 1: Create a viewport in the layout space by entering the command MV to create a rectangular viewport ； Step 2: Viewport cropping – Right-click on the selected rectangular viewport and choose Viewport Crop. Furthermore, you can also draw the shape of the viewport according to your needs, as shown in the figure below. If you need to create circles or other specified shapes, you can draw the desired graphics before selecting the view crop. After selecting viewport cropping, choose that graphic as the cropping object. The above are some basic tips for beginners in CAD drawing; you can refer to this CAD tutorial when encountering similar problems in the future~
