This topic contains important information for Autodesk AutoCAD LT.
The ZIP option of the DWGCONVERT, ETRANSMIT, and ARCHIVE commands now create UTF-8 ZIP files, which uses the popular 8-bit form of Unicode for file names. This means that you can package files that have names with extended font characters. The file names will not display correctly if you use ZIP utilities that don't support UTF-8 ZIP files. Use a ZIP utility such as 7-Zip to correctly display and extract these files.
Starting with AutoCAD LT 2017-based products, BMP files no longer support the color value of 192,192,192 as a transparent color. Custom images that need to support transparency must now be saved as a PNG file.
Using ACCoreConsole to publish will only publish drawings using software Z-buffer rasterization. If you want to plot using hardware accelerated rasterization, you should plot or publish through AutoCAD. BGCorePublish utilizes ACCoreConsole and should be turned off to use hardware accelerated rasterization.
On the Windows 11 operating system, OLE image objects (BMP, PNG, GIF, and so on) don’t display and can’t be plotted as expected. This is due to a limitation in the Paint application that ships with Windows 11. AutoCAD LT is affected the same way other Windows applications are affected. For more information, see Pasting an Image into a MS Access Image (OLE Object) Control Doesn't Work in Windows 11.
