  Chain links 3711 / treads 3873
Posted by: Sylvain Sauvage - 2022-07-25, 20:07 - Forum: General LDraw.org Discussion - Replies (5)

Hi all,

3711/3873 both have a span (distance between connectors) of 16LDU.

IRL, the distance is slightly bigger.  It’s about 2.7% more.  (Measured while digital-building 10303: it needs 262 links in digital, while 255 (222+33) are in the set / instructions.)
That would make a span of about 16.4LDU.

So, two questions:

1. Am I the only one bothered with that?  I.e. not having the correct number of parts in digital builds.

2. Could it be changed?  Or is there a rule (that I didn’t find) somewhere saying that it can’t?
I mean, excluding backward compatibility rules.  So to rephrase the question: Could a similar part be built & officialized with a span of 16.4LDU?

  Unpatterned versions of patterned parts
Posted by: Max Murtazin - 2022-07-24, 14:14 - Forum: Parts Authoring - Replies (2)

Is there a need to upload unpatterned versions of parts that have appeared in patterned variants only? (For example most Bionicle dual injected parts) And if no, are such unpatterned versions allowed on the part tracker?

  Find subfiles that are not used correctly
Posted by: Magnus Forsberg - 2022-07-24, 6:57 - Forum: Parts Tracker Discussion - Replies (3)

Is there a way to find subfiles that are used in a patterned part, but is not used in the unpatterned version of the part?
IMHO it's bad practice to derive a new subfile from an existing part and then not update the file it came from.

  Advanced rotation techniques
Posted by: N. W. Perry - 2022-07-22, 13:40 - Forum: LDraw Editors and Viewers - Replies (12)

I feel like I'm under-using LDCad's advanced rotation capabilities. But instead of a question, I think it's easier to just give an example—and sort of a challenge. Smile

In the attached test file I have an oddly-shaped piece that I want to rest on the ground, here represented by a nice big tile. This part has four lower extremities, all with different y-values, and to be realistic it would need to rest against the lowest three of them. What's the best way to do this using LDCad?

   
.ldr   test.ldr (Size: 173 bytes / Downloads: 2)

Here's how I would approach it:

  1. Find the lowest point and set it as the rotation center. You could use a helper part or a marker, but how do you find the point itself? Easiest way would be if you could directly select the vertex—LDCad can't do this, but LDPE can.
  2. Find the next lowest point the same way, then using more helper parts and some trigonometry (or the handy, but unofficial, right angle calc script), rotate the part so this hits the ground.
  3. For the final rotation, select the third low point, and rotate around a vector formed by the first two points. LDCad does allow custom vector rotation—but how do I find the vector and enter it into the rotation dialog?
Even better would be if you could select all three points at once and use them to define a plane, then set the part's absolute rotation just once so that this plane matches the ground plane. This could probably be scripted, but there's still the problem of selecting the points in the first place.

Is there a better way? How would you approach this problem?



(Can't attach the .lua file for the angle script, but here it isSmile
Code:
function onRun()

  local sel=ldc.selection()
  if sel:getRefCount()<3 then
    return
  end

  local a=sel:getRef(1):getPos()
  local b=sel:getRef(2):getPos()
  local c=sel:getRef(3):getPos()

  local ba=a-b
  local bc=c-b

  local n=bc:getCross(ba)
  n:normalize()

  local bb1=n:getSignedAngle(ba, bc)
  local bb2=math.deg(math.acos(bc:getLength()/ba:getLength()))

  local angle=-(bb1-bb2)
  ldc.setClipboardText(angle)

  ldc.dialog.runMessage(angle)
end

function register()

  local macro=ldc.macro('Right angle rotation calc')
  macro:setEvent('run', 'onRun')
end

register()

  Changes per page button/setting on parts tracker activity page
Posted by: Max Murtazin - 2022-07-20, 22:45 - Forum: Website Suggestions/Requests/Discussion - Replies (4)

I think part tracker would benefit from having a way to select number of changes displayed per page in Parts Tracket activity section. You can already do that by changing link, for example: 
https://www.ldraw.org/cgi-bin/tracker/ac...gi?n=0,100 gives 100 edits per page, also (and similar thing is applicable to other variants) clicking "next" does indeed offset list by 100 
https://www.ldraw.org/cgi-bin/tracker/ac...cgi?n=0,20 gives usual 20 edits per page
https://www.ldraw.org/cgi-bin/tracker/ac....cgi?n=0,1 gives 1 edit per page (why? idk, just an example)
This is already implemented in the section, so only thing it actually needs is a way to select that on page

Sad Recreating Lego racers 1: Missing essential parts

Hey guys! I am currently trying to rebuild the LEGO racers 1 cars with their characters, but I am missing some essential items to make it work. Does anyone want to create these parts and add them to the parts tracker?
