Hi All,
As long as we're updating documentation, I'd like to create a list of the
known meta-commands.
The process for defining new meta-commands is completely unregulated, which
is fine, but as a newcomer to LDRAW compatible CAD tools development, I'm
concerned about reuse of meta-command keywords. The first level of concern is
the meta-command name space issue. The second is the definition of what the
meta-command does and what its parameters are.
I've introduced my own meta-commands and have documented them to some
degree. MLCad's new meta-commands are documented in the MLCad Lizence.
Obivously the LDraw meta-commands are documented as well. I know there are
other applications that define their own meta-commands, and I'd like to gather
the list.
Would the authors of LDraw compatible applications please list the
meta-commands they have created? I will compile the list of applications and
the meta-commands they define.
Kevin

| I have some LTrax commands. (LTrax is an LDraw compatible "Track Designer") The LTrax are not 'official' LCad commands, but I wish to reserve the keyword. 0 LTrax Position <x y z> 0 LTrax Angle <v> [Degs*] 0 LTrax Object 9Volts\Straight.txt** 0 (...) (22 years ago, 14-Mar-03, to lugnet.cad.dev)

| (...) One thing that I think would help reduce namespace pollution is if everyone did what LTrax did... prefix the command with the app name for uniqueness. Not a perfect solution, of course. (22 years ago, 14-Mar-03, to lugnet.cad.dev)

| I have invented a 'general purpose' header statement, 'Parent:' that points to the parent[s] of a model file. See example below. I find it very useful when sorting out Datsville submodels, and also in animations. I also use the 'Was:' statement for (...) (22 years ago, 14-Mar-03, to lugnet.cad.dev)

| Having read through this thread, I've seen a lot of good points made. However, it also appears that people haven't really fully thought about the implications of meta-commands. It's very important to realize that meta-commands are presented as (...) (22 years ago, 14-Mar-03, to lugnet.cad.dev)

| Hi All, Wow! This thread has created more postings that I thought it would. So far I've gathered meta-commands from (URL) Eriksson LTrax, Parent: Kevin Clague - LPub and LSynth There must be more. If you know of programs that define their own (...) (22 years ago, 15-Mar-03, to lugnet.cad.dev)

| Hi All, Well, this topic has exceeded the 100 post mark! The bummer is that we can no longer see the tree view of the posts :^( Here is the first draft of a list of meta-commands. It is pretty rough format-wise, but at least it is a list. I'm still (...) (22 years ago, 19-Mar-03, to lugnet.cad.dev)
