Understanding the "AutoCAD Block Host File Updated" Message: Causes and Solutions If you encounter issues with your block host
Prior to AutoCAD 2018, if you attached a drawing (Xref) containing blocks, and that Xref was unloaded, the block definitions would often disappear from the host drawing's database. The "Updated Host File" behavior (introduced in recent versions) ensures that block definitions from attached Xrefs remain accessible in the host file even if the Xref is unloaded or not found.
In AutoCAD, a block host file is a file that contains the definitions of blocks used in a drawing. When you create a block in a drawing, it's stored in the block host file, which is usually the drawing file itself (.dwg). However, when you insert a block from an external file, the block definition is stored in a separate file called a block host file (.bhl).
