HCAD CAD 2020 was officially released last week. In addition to offering a brand-new visual experience, its functional capabilities have seen significant improvements and optimizations. The powerful feature of \"direct PDF editing\" has received tremendous acclaim from users. While expressing their admiration for the growing strength of domestic software, users are more interested in learning how to use this new feature to achieve rapid drawing from PDF to DWG! Without further ado, here is the tutorial carefully prepared by the editor to help you quickly understand this powerful feature of \"direct PDF editing\". Step 1: Use the “PDF Input” function to open HaoChen CAD 2020; you can find it under the “Insert” option, or you can use the command line command PDFIMPORT. (Figure 1: PDF import function in HaoChen CAD 2020) Step 2: For the “PDF Import” settings, select the PDF file that needs to be opened. For multi-page files, the number of pages in the PDF will be automatically detected; you can choose which pages to import, determine the insertion location on the interface, and adjust aspects ratio and rotation angle as needed. Input PDF data option box. By default, \"Vector Graphics\", \"Solid Filling\", and \"TrueType Text\" are checked; if lines, fill, and text in the PDF graphic are not required, uncheck the corresponding options. The “Raster Image” option is selected when there are images in the PDF. Layer options box. The software offers 3 layer management options, which can be selected as needed. Enter option box. This option is primarily used to determine the format in which the imported content will be displayed, offering 5 options for you to choose from depending on the situation. (Figure 2: PDF input and its corresponding settings) Step 3: Reading CAD information. PDF import is just the first step; the key lies in how to read the information completely. The editor compared the original image with the graphic after importing it from PDF and found that all the information was exactly the same, demonstrating perfect reading of the information contained in PDF drawings and enabling efficient use of these drawing resources!

With it, the “design lions” no longer need to worry about PDF format conversion! Three steps to unlock the new “PDF→DWG” skill, easily handle various types of drawing documents, and embrace a new mode of “fast drawing”!
