Ok, this isn’t rocket science, but some people don’t know about this.

If you want to assign a block to represent the point style, but it does not exist in the drawing, you can insert it without leaving the Style Editor.


Right Click in the Block list, and the ‘Browse…’ option will appear.  Select it, and Windows Explorer will let you navigate to the location, and insert the block you select.  This is a really nice feature.
