Hatches And Snapbase

[Anonymous]

You can control where a hatch pattern starts with snapbase. Is there any
way to quickly edit the hatch patterns "starting point" after creating the
hatch. Sort of a stretch the base point or drag the definition point?

Using HATCH and BASE as keywords to search the Customization discussion

Here is a lisp from the Cadalyst website (Oct 1999), that adjusts the
origin

of a hatch pattern after it has

been created.

;Tip1560:    ADJUST.LSP    Adjust Hatch   
(c)1999, Ali Khalfan

(defun c:adjust (/)

(setvar "cmdecho" 0)

(setq OBJ (entsel "\nSelect Hatch pattern to edit:"))

(setq PT1 (getpoint "\nSelect new starting point of hatch pattern:"))

(setq XCORD (car PT1))

(setq YCORD (cadr PT1))

(setq SP1 (list XCORD YCORD))

(setvar "snapbase" SP1)

(command "-hatchedit" OBJ "p" "" "" "")

(command "snapbase" "0,0")

(princ)

)

;;; end adjust.lsp

If I understand your question correctly - what I do is make a temporary copy of the hatch just off to the side somewhere, reestablish the new snapbase point that you want, then pick "Match Properties". When it asks "Select source object:" select the hatch COPY, then when it asks "Select destination object(s):" select the hatch that you want to change. The hatch should update with the new snapbase point.

After changing the snapbase: Type the command hatchedit. Do not change anything about the hatch, simply hit ok, and the hatch automatically updates to the new snapbase.
