parts tracker: "BFC rationalisation" |

This post explains the small history line "BFC rationalisation" which appears
in the bunch of updated official files that Chris just has uploaded to the PT for me, thanks, Chris!
I had recently done a systematic syntax check of all currently official files.
Through this I discovered these files having some common glitches, which I ironed out.
They were:
(a) appearance of header elements throughout the file, mostly due to inlining relicts, e.g. "Name: xyz" or "BFC CERTIFY CCW"
(b) repeated BFC CERTIFY statements throughout the file (probably due to MLCad save operation)
© changing of winding from CW to CCW or vice versa inside the file (usually a result of inlining)
(d) other syntax errors

UCS Millenium Falcon Animated Build Rendered With LDView |

Hi All,
I hope this is OK to post here...
Having previously created a number of animations using POV-Ray for rendering the frames I thought I would try using LDView to render the frames required instead. (Thanks to Travis (author LDView) for answering a number of my questions in this forum which helped me to get this working).
First online result of this can be seen at the folllowing link:
http://www.youtube.com/watch?v=Y7Iq3wju3O0
Rendering this is POV-Ray would take about 100 times longer... (Such as http://www.youtube.com/watch?v=TudW-8FjMzE)
The 'falling parts' code (my software) is new and rather than one part falling at time (which is how I have done these animations previously) now multiple parts are in motion in any one frame. The 'algorithm' is not perfect yet, some parts still 'fly through' other parts - work in progress ...

separating metal portions of 9V train track |

I was wanting to separate the metal portions of
http://www.ldraw.org/cgi-bin/ptdetail.cg...859c00.dat
into 1 or more separate files.
Reason for this was that in the current implementation,
when you use that part in a model,
and you assign some color to it,
all edges on metal appear in that color,
this makes that part look weird.
Reason for that is that all edges and optional edges in that file
are coded in color 24, regardless whether they bound plastic or metal parts.
My problem is now this:
I can easily identify quads and triangles of color 494 (metal) and move them to a separate file.
Second step should have been to also move their bounding edges and optional edges there.
Would I have finished that, then the color problem would be gone, because in that new file X.dat,
I would use color 16 for quads and triangles, and 24 for edges and optional edges,
and then reference that file from 2859c00.dat, using color 494. This way, both the surfaces and
the edges would appear in correct color.
However, identifying which edges to move to X.dat is terribly difficult.
There are tons of such edges, and manual selection will introduce lots and lots of errors.
To accomplish this task, I would need help of a tool which doesn't exist yet.
It would let me specify some color, by which I would like to identify affected quads and triangles
(here: 494).
The tool should then run through the file and identify all edges and optional edges which bound
these, i.e., which share coordinates with them.
Using such a tool, it would be easy to find all edges in 2859c00.dat which need to be moved to a separate file.
(Of course, from a logic point of view, each own metal portion should probably go into its own,
separate ~part file, but to me that's second priority. Solving the miscolored edges problem has first.)
Unfortunately, without this tool, I sadly have to give up on this task for now :-(

How to get the unofficial parts library to work in Mac OS |

Hi,
This afternoon I've been looking at the cool 'unofficial parts library', they looked good on the website but when I opened them in Bricksmith I cept getting 'Bricksmith couldn't find all of the pieces in this file. The following are missing: s\xxxx.dat, s\xxx.dat', (those filenames are just an example) and realized why this was, it's because all of the file 'scripts' / contents when opened in a text editor have an '\' in them when it should be an '/', replacing all of them allows Bricksmith to find the subparts (located in the 's' directory).
Now, the problem was editing these thousands of files so I found a program called textmate ,when I went back the parts opened fine with no errors and had no changes to the file extention.
Here's how to fix this:
Download the unofficial parts library and extract the 'LDRAWUNF' directory to the bricksmith folder so you have the folders 'LDRAW' and 'LDRAWUNF' (LDRAW should already be there as it comes with bricksmith).
Find the 's' subfolder in 'LDRAWUNF'>'parts' and move it onto the desktop (make sure it is moved not just duplicated).
Download 'Textmate' then after installing. goto 'file', 'open'.
Locate the 'parts' folder in 'LDRAWUNF' and in the parts folder select all of the dat files and hit 'open'. (there should be nothing but .dat files in that folder since we moved the 's' folder).
Goto 'edit' and click 'find', then 'find in project'.
Type in the 'find' bar '\' (with no quotes) and hit 'find'.
In the 'replace' box, type in '/' (no quotes) and hit 'replace all'
Close the box and go to 'file', 'save all'.
Now go ahead and move the 's' folder back into the 'parts' folder in 'LDRAWUNF'
All or most parts should now return no errors when being opened.
***NOTE*** the 'parts' or 'p' folder containing official parts that comes with bricksmith should not be touched for this fix.
Note to mods, Im not sure what category of the Ldraw forum this should be located in.
