ceiling grid

Does anybody know of any lisp routines and where to get them, for Autocad 2005 that will create a ceiling grid?.

 

Will a hatch pattern do?

In the customer files newsgroup, check the message titled "Ceiling Grid
lisp". Attached to that message is a lisp file that facilitates the
insertion of ceiling grid hatch patterns. It allows centering by corner
points, rotation option, and dynamic shifting of the grid pattern depending
on how the tiles are oriented on the center point (i.e. centered, on a
corner, vertical midpoint, horizontal midpoint)

It does assume you have a couple hatch patterns defined, but examples are
included in the documentation.

Thanks for the advice but not exactly what I am looking for. I want to be able to have a 600x600 grid, with the intersection of the grid lines at the centre of a room.

 

Use a "user defined" double hatch pattern with the spacing defined at 600;
set your SNAPBASE to the center of the room before hatching (or while using
HATCHEDIT).

Simple modification for your needs:

*ACT-600sq,Acoustical Ceiling Tile 600x600, Single-Line
0,0,0,0,600
90,0,0,0,600

[Or use a plain old User-defined hatch with 600mm spacing, double]

Set the snap origin point [(setvar "SNAPBASE") or with the Rotate option in
the Snap command, giving it an origin point but not necessarily a rotation]
to the centre of the room before hatching. There have been various
approaches in this newsgroup recently to calculate the midpoint between two
points, to get that room centre from the corners of the room (assuming it's
a rectangle), or you can draw a diagonal line and set SNAPBASE to its
midpoint.

(And if it matters, be sure to set the snap origin point back afterwards.)

Do you mean a grid filling a 600x600 area, or a grid where each "tile" is
600x600? A 600x600 tile is 50' by 50'. That's one huuuge tile!

Ahhh ... I think he's working in millimeters, not inches...

No, the 50'x50' tiles are made so you can just trim to fit.
