Mastering Viewing Tools, Hatches, and External References
2018
This chapter helps readers to learn how to: assemble the parts, take control of the AutoCAD display, use hatch patterns in drawings, understand the boundary hatch options, and use external references (Xref). AutoCAD uses two commands for refreshing drawing display: Regen and Redraw. The tool palettes give access to frequently used blocks and hatch patterns that reside in other drawings. In standard AutoCAD installations, the tool palette window is configured with sample 3D commands, blocks, and hatch patterns that one can drag and drop into current drawing. Xref files, like blocks, can be edited only by using special tools. One can, however, use osnaps to snap to a location in an Xref file, or can freeze or turn off the Xref file's insertion layer to make it invisible.
