To see a selection of popular online Lisp resources, go here: To see how custom Lisp routines can be loaded in AutoCAD LT and add them to a start-up suite go here: This bespoke hatch pattern is a genuine hatch entity that can be trimmed, edited and queried for areas etc. The routine also loads the new custom hatch pattern into the current AutoCAD LT drawing for testing. Once complete, the Savehatch command will ask the user to select the entities for the hatch, ask for a brief description and then ask for the name and location of the hatch pattern file to save to. If not, the elements will either be ignored or result in a hatch error creation message. The constraints mean elements must be drawn within a 0,0 to 1,1 limit and lie on a 0.01-unit grid.

The Drawhatch command defines a boundary area, measuring 1 unit by 1 unit to provide the user a framework to define a custom hatch pattern with line and point entities. With these commands users can draw a bespoke hatch arrangement using simple entities.

Once hatchmaker is loaded the routine provides two new commands DRAWHATCH and SAVEHATCH. Save Hatchmaker.lsp to a suitable support folder and keep it there alongside any other useful routines!Ī Lisp file is just a text file of a few kilobytes and once loaded via the Appload function, can be added to the startup suite. Locate a Lisp routine on a resource such as Or specifically the Lisp routine can be accessed here: However with AutoCAD LT 2024 and the recent inclusion of AutoLISP support the answer is yes! The short answer is no! At least not out of the box. Can I not draw some kind of symbol, make it a block and incorporate it as a custom hatch pattern? When training AutoCAD LT I often get asked is there an easy way to create hatch patterns especially for landscaping and site plans.
