Method 1, step: 1. After handwritten signature, scan it with a scanner or shoot it with a digital camera. It is better to have a higher pixel and save it as a raster file; 2. Insert the signed raster image into the AotoCAD interface; 3. Use the "multi-segment line" command of AotoCAD to draw the signature downward in the raster image, just like when I was a child, if the line was too thin, I could make it thicker; 4. After modifying the perfect face, zoom to the appropriate size; 5. Use the BLOCK command to save the multi-segment line signature as a block, and copy and paste it to the corresponding position every time (at this time, the raster image can be deleted). 6. The method of removing the border: modify-object-image-border, and eliminate the text border. Method 2: To get the hollow signature by scanning, there are several steps: first, scan the name, and pay attention to making the pixels as large as possible for editing in Photoshop; Second, select the text in Photoshop, and then turn the selection into a path; ; Third, export the path file of the name to explain the format (pay attention to the format); 4. Open 3dsmax and import the illustration format file with this name; Fifth, the last step, the exciting moment has arrived, and the file is exported again, but this time the export format is. Dwt format, that is, the format exported to CAD; 6. Open the file in 3dsmaxExport just now, and your name will be displayed in front of you (just the CAD signature you want). Method 3: Insert the jpg file directly into the frame and adjust the frame to not display. Just refer directly! When copying a file, copy the picture frame together with the jpg file. The fonts printed by this method are not very clear. Method 4: To get a vectorization, you need vectorization software, such as AlgolabPtVector.
