Methods to optimize the AutoCAD system

Methods to optimize the AutoCAD system: I. Optimize the Windows system 1. Clean up and maintain the disk to improve Windows performance. If AutoCAD malfunctions, it may cause the swap files to be terminated abnormally, resulting in the loss of some disk clusters. The Windows system automatically checks for missing disk clusters when it starts up. If you do not want to restart the system, you can run chkdsk from the command line. 2. Defrag the disk to optimize Windows system performance. What is disk fragmentation? The various parts of the same disk file are scattered across different areas of the disk, and fragmentation occurs when old files are deleted and new files are added to the disk. It slows down disk access speeds and reduces the overall performance of the disk. Just as a novel is not printed on consecutive pages, but instead “turn to page xxx” appears every few lines. When AutoCAD is running, it needs to create certain temporary files on the disk; if these files are scattered across fragmented areas of the disk, it will naturally slow down. Run the \"Disk Defragmenter\" to organize disk fragmentation? II. Optimizing the AutoCAD system 1. Optimizing 2D polylines and associative fills created in AutoCAD R13 or earlier versions. Starting with version R14, AutoCAD creates 2D polylines and associative fills in an optimized format that helps save memory and disk space. Use the CONVERT command to update hatch patterns or polylines created in AutoCAD R13 and earlier versions. 2. Remove unused named objects from the graphic database to effectively reduce the size of the graphic file. Over time, some unnecessary named objects (objects that are not drawn in the graphic) may accumulate within it. For example, graphic text that no longer uses any text styles, or layers that contain no graphic objects ； Even worse, it includes huge unused blocks and so on. The cleanup operation only removes references at one level. It may be necessary to repeat the process more than three times to completely complete the cleanup. Note that if waste cleanup is performed at the start of drawing, it may delete the defined drawing templates. 3. Grouping significantly slows down the speed of selection operations; it should be removed. A group is a named set of selected objects, and unlike unnamed selection sets, a group is saved along with the graphic. Grouping belongs to named objects, but unfortunately it cannot be removed using the PURGE command. If an object is deleted or removed from a group, leaving the group empty, the group remains as originally defined. If there are a large number of empty groups, it severely affects the selection speed. 4. Network version optimization: Whether AutoCAD is installed on a network server or on a client workstation, users can share data stored on the server’s hard drive, while keeping the graphics they do not want to share on their local hard drives. Each of the two methods has its own advantages. Installing AutoCAD on client workstations can optimize network performance. Installing AutoCAD on a server allows users to share an executable file, thereby saving disk space and **simplifying** the installation and upgrading of the software. You can also combine client installation with server installation based on your network configuration. 5. Load external references on demand and optimize their performance. By combining on-demand loading with the saving of graphic indexes, it is possible to improve the performance of graphics that contain external references. When on-demand loading is enabled, if the index has been saved in the reference drawing, AutoCAD will load only the data related to regenerating the current drawing from that reference drawing into memory. In other words, the reference material is read as needed. The excellent performance of on-demand loading is manifested in: (1) clipping external references to display only a small portion of them, with the spatial index being saved in the external reference file ； (2) Freeze several layers of the external reference, and the layer indices are saved together with the external reference file. 6. Load other geometric shapes into the locally opened graphic. When working with a very large graphic, you can use the “Locally Open” option to select the views and objects in the layers that need to be processed (limited to graphic objects). After the drawing is partially opened, the PARTIALOAD command can be used to load other geometric elements into the drawing from a view, a selected area, or a layer.
