Idea for LUA script to create a knolling layout

[Roland Melkert]

I made some adjustments to the script to reset rotation and prepare for inlining. I'm not sure how to inline in LDCad script so here I might need Roland.

You could build a flattened list of all used subfiles (parts) with their abs position and other needed info.

This is done recursive on the refs like:

Code:

function buildFlatList(parentSf, parentPosOri, list)

  local cnt=parentSf:getRefCount()

  for i=1, cnt do

    local ref=parentSf:getRef(i)
    local sf=ref:getSubfile()
    local relPosOri=ref:getPosOri()
    local absPosOri=relPosOri*parentPosOri
    
    if sf:isPart() then
    
      local item={
        pos=absPosOri:getPos(),
        sf=sf
      }
      
      table.insert(list, item)
      
      --print(item.sf:getFileName() .. ' => ' .. item.pos:__tostring())
    else    
      if sf:isGenerated() then
        --collect/map flex info if needed, for now just skip it.
        --print('flex: '..sf:getFileName())
      else
        buildFlatList(sf, absPosOri, list)
      end
    end
  end

end

and use it like:

Code:

local list={}
  buildFlatList(ldc.subfile(), ldc.matrix(), list)
  -- sort/use list etc

Also I think the overlap are caused by not compensating for the parts absolute center. The bounding min max vecs are not symmetrical.

Small tip:
setIdentity is not needed a new ldc.matrix defaults to identity. (technically it is noise until used internally, but from pov of the user it will be id)
