Hi all,
As any of you that have gone to the piece voting page know, there is a problem
that needs to be resolved concerning the large Technic shock piece.
To (sorta) quote from the page:
-----------start-----------------------
There is a problem with this piece. We need to decide how to best add it to the
inventory.
Unlike the 731.dat/732.dat Technic Shock Small, we can't just divide it into
two pieces. It works for the small shock because the spring is hidden inside
the body of the part. Moving the two pieces together or apart looks pretty
good.
This piece, 2909c01, has this external spring. We must decide on a different
way of handling it. Some proposals:
1. Add the upper and lower pieces, along with its two small component spring
subpieces. This would require the user to custom build the entire spring
section manually. (kind of difficult)
2. Add the upper and lower pieces, and add a small selection of spring lengths
to choose from. This method would give a little leeway in adjusting the final
length of the shock by allowing the user to "fudge" a tiny bit on the placement
of the upper and lower pieces.
3. Add a small variety of shock lengths as complete assemblies. This would
mean that each assembly would be a fixed length, and not allow for any
adjustment.
Right now, the element exists as:
2909c01 the composite shortcut of the entire piece.
2909.dat the upper half with printed number.
290.dat the lower half.
Two subfiles in the S\ directory for the spring.
---------------end--------------------
My personal preference is for solution #2.
This way would allow for at least a tiny amount of adjustability in the length
of an assembly when modeling.
Second choice would be #3. Simple to use, but this way has the drawback of not
having any adjustability.
And I would not even consider using #1. I am not a masochist.
Whether we use #2 or #3, we need to also figure out which lengths to include in
the inventory. I would like to keep the number of discrete files to an
absolute *minimum* - having too many would be awkward.
Some people may raise the question of just having one spring length, and then
stretching or compressing it by altering the scale of the piece along one axis
in the dat file. This could work, but it is also a bit tricky to do. I am not
an expert, but I consider myself fairly adept at modeling in LDraw. And I have
trouble scaling things properly. It is always a trial-and-error operation for
me. This approach can also make the spring appear strange in the rendering,
especially so when ray-tracing. This is because it distorts the spring
structure.
So, while possible to do it this way, I don't think it is the ideal way. This
method would be useful when used in conjunction with solution #2 though. At
least it would be useful for the anal-retentive modeler. A premade spring
length that is _almost_ the correct length could be lengthened or shortened a
*tiny* bit with little or no apparent distortion.
OK, I have (as usual) rambled on to long. Any comments/suggestions/questions?

| (...) I have a fourth idea. It's a bit difficult to explain, but I'll try to make it clear: There would be a total of 3 pieces to make up the shock: A) Shock lower w/ half of spring B) Shock upper C) Spring upper half Since the spiral is fairly (...) (26 years ago, 9-May-99, to lugnet.cad.dev)
