Mirror object automatically

jonathan.craig — Fri, 10 Nov 2017 20:17:32 GMT

Hi,

I am looking for a way to get entities too be automatically mirrored from a reference axis And updating everytime i put a new object.

im a working on a structure on a deck of a boat. I want to be able too work only on one side of the boat as the other side of the reference line in red mirrors automaticaly everything i do over it.

Hope this is clear.

thanks !

Ps: here the link of what i want to achieve (not in 3d tho)

Define one half of it as a Block, Mirror that across the center-line axis, and do your working-on-it within REFEDIT or BEDIT. When you get out of that and Save the changes, the other side will update.

Kent's advice is very sound. I much prefer refedit to bedit. I only use bedit if I'm going to use dynamic properties in a block.

I use blocks a ton and refedit alot so I wrote some simple lisp to help speed the editing up.

(Defun C:TLC-Reference_Edit ()
(setvar "cmdecho" 1)
(command "-refedit" pause "O" "A" "Y")
(setvar "cmdecho" 0)
(progn)
);defun

and

(Defun C:TLC-Reference_Save ( / tlv-refname)
(if (/= (getvar "refeditname") "")
(progn
(setq tlv-refname (getvar "refeditname"))
(command "refclose" "s")
(command "attsync" "n" tlv-refname)
);progn
(princ "Not in Ref Edit Mode. Exiting")
);if
(princ)
);defun

You can add to your .pgp file like I did if you like:

RED, *TLC-Reference_Edit
RS, *TLC-Reference_Save

What's wrong with the Extend command, especially with Fence? Or are the port->starboard lines supposed to be separate, port and starboard?

Surely nothing's wrong with Extend, but widen your horizons -- there are so many other kinds of "work" they might want to do on it [add linework running in other directions than perpendicular to the mid-line, openings, bolts, re-shape the perimeter, hatch areas, etc., etc.].
