Here again is an optional fix. This will convert new brown in LDD models to old
brown in LDRAW, which is more convenient to edit in MLCAD:
First, comment out the old brown definition:
<!-- OLD BROWN, removed by Jason Railton 30.Jun.06 -->
<!-- colour tabulaname="25">6</colour -->
Then, comment out the new brown definition:
<!-- NEW BROWN, removed by Jason Railton 30.Jun.06 -->
<!-- colour tabulaname="192">70</colour -->
Finally, add in this crossover definition:
<!-- NEW TO OLD BROWN, remapped by Jason Railton 30.Jun.06 -->
<colour tabulaname="192">6</colour>
As for parts, I tried to do the 1x1 plate with tooth from the LDRAW Parts
Tracker (part 49668):
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=parts/49668.dat
The re-orientation definition required is "y + 0.320" (down a plate) and rotate
Pi radians about the y axis (turn round 180°):
<!-- 1x1 PLATE WITH TOOTH, added by Jason Railton 30.Jun.06 -->
<origin x="0.000" y="0.320" z="0.000" axisx="0" axisy="1" axisz="0"
angle="3.141593">49668</origin>
And the part definition is simply:
<!-- 1x1 PLATE WITH TOOTH, added by Jason Railton 30.Jun.06 -->
<geometry tabulaname="49668">49668</geometry>
But, this doesn't work. If you place a tooth on your model in MLCAD, LDD will
import it in the right place. But, if you save the model from LDD in '.ldr'
format, the tooth will disappear. Re-loading the '.ldr' file can precipitate a
crash, too.
Contrary to some suggestions based on LDD 1.5, LDD 1.6 refers to all colours of
this part as "49668". I still don't know why this doesn't work though - it
worked for the 1x1x2/3 slope.
