Why isn’t the line width visible even though the “Show Line Width” setting is enabled in CAD?
Thread Content
I received a very strange CAD file (of the usual dwg format), and although the option for \"displaying line widths\" was enabled in the settings at the bottom, the line widths still weren’t visible. Later, I entered the “LW” command and checked the option to display line widths again in the line width settings dialog box; however, I found that the line widths were only visible for a moment before they all reverted to thin lines once more. It’s like I’m poisoned. I don’t know what’s going on here. Which program could be preventing the display of line widths? Is there a virus built into this file? It’s just this one file that’s strange; all the other CAD files are fine.
This situation is indeed quite strange, but don’t worry; the possibility of the file being infected with a virus is very low. CAD files are not particularly prone to being infected; it’s more likely that issues arise from settings within the file or display conflicts. Common reasons might be: 1. The line width setting in the file has been overridden by a certain layer or style; for example, the layer properties may specify “do not display line width”” ； 2. Issues with the view display mode; for example, in the “2D wireframe” mode, the line width is sometimes ignored ； 3. There is a problem with the graphics card driver or the display cache of the CAD software itself. You can try these methods: - Enter the “LAYER” command to check whether line width display is enabled for all layers ； - Switch the view mode, for example, from “2D Wireframe” to “Realistic” or “Conceptual” to see ； - Restart the CAD software, or try repairing the installation file. If that still doesn’t work, it’s possible that special settings or plugins were used when this file was created; it is recommended to use the \"AUDIT\" command to check for errors in the file. .
It is possible that it was created using another CAD software, which has settings functions that are not available in Autodesk CAD, or that the current version does not have such settings functions.
