Hatchings for insulation

[Little Bandit]

I'm wondering how ppl make those insulation hatchings for insulations - the one that looks like squizzed line and the curves are always touching edges - like the one in the attached file. I have a feeling that it's some kind of polyline or a dynamic block really.

Talking bout hatchings, Where is AutoCAD storing all .pat files? I downloaded some hatches that may be interesting and dunno where to save them.

You can save .pat files anywhere, just create a new "Support File Search Path" that points to the folder where your .pat files are saved. In the screen shot below, you can see the path I created for my hatch patterns.

Hatch can be saved in
C:\Documents and Settings\Administrator\Applications Data\Autodesk\AutoCAD 2008\R17.1\enu\Support

It is not a hatching, but a linetype called BATTING

Use the 'filesearch' on yer PC to find exisitng *.pat files.

Haha, mystery solved

The batting in the attached drawing is not using the batting linetype.

It was probably created with a lisp program to draw insulation in a wall.

; arcs only based on 90 mm high INSULATION

(progn
(setq N (fix (/ (distance p1 p9) (* 90.0 (/ insul_ht 90.0)) )))
(setq d1 (/ insul_ht 2.0))
(setq p2 (polar p1 (+ 1.5708 ang1) d1))
(command "pLINE" p2 "w" 0.0 0.0 "a")

(setq m 1)
(while (<= m N)
(setq p3 (polar p2 ang1 d1))
(setq p5 (polar p3 ang1 insul_ht))
(setq p6 (polar p5 ang1 d1 ))
; now put pts 3,4,5,6
(command "ce" p3 "a" "-180" "ce" p5 "a" "180")
; parallel lines now drawn
(setq m (+ 2 m))
(setq p2 p6)
)

(command "")
)

Hey BIGAL,

Where is the rest of the program?
