    Looking for dimensions of LEGO bricks. —David VinZant
   Hello all, I have been playing around some Cad software called SolidWorks and would like to model LEGO bricks. Is there a resource for accurate dimensions of LEGO parts? Dave (15 years ago, 22-May-09, to lugnet.cad, FTX)

   (...) Hi Dave, check out the LDraw Specs 1.0.0 at: (URL) easy way to convert mm in LDUs is Mike Heidemann's prog LDCalc: (URL) miss Marc Klein's website for modeling tips in SW as well as converting SW data into .dat: (URL) this helps. w. (15 years ago, 22-May-09, to lugnet.cad)

   (...) IIRC, *real* Lego parts use Imperial units, so converting to/measuring using the metric system will involve lots of decimal places. -Mike (15 years ago, 25-May-09, to lugnet.cad)
   
        Re: Looking for dimensions of LEGO bricks. —Timothy Gould
     (...) Given that Denmark went fully metric in 1912 and that a 1x1 brick is 8mm x 8mm x 9.6mm (stud exclusive) it seems unlikely that imperial will work out better for you. Although it does so happen that 8mm is quite close to 5/16inch. Tim (15 years ago, 25-May-09, to lugnet.cad)
    
         Re: Looking for dimensions of LEGO bricks. —Mark Kennedy
      (...) When I measured a 32 X 32 baseplate it was 10 inches. From my understanding 1 LDU is about equal to 1/64 inch. The Lego company though would surely be able to give you precise meaurements. (15 years ago, 25-May-09, to lugnet.cad)
    
         Re: Looking for dimensions of LEGO bricks. —David Laswell
      (...) Huh. I was about to point out that a 48x48 baseplate is 15" per side, but it turns out it's actually just shy of 15-1/8". Conversion gets you 381mm based on a 15" baseplate, and 384mm based on an 8mm 1x brick, and that 3mm difference is just (...) (15 years ago, 25-May-09, to lugnet.cad)
    
         Re: Looking for dimensions of LEGO bricks. —Allen Smith
     (...) That's hardly some freak coincidence. The original 1949 Lego brick was an unauthorized copy of the Kiddicraft Self-Locking Building Brick, invented by an Englishman named Hilary Page. When the Christiansens got samples of them from the British (...) (15 years ago, 28-May-09, to lugnet.cad, FTX)
    
         Re: Looking for dimensions of LEGO bricks. —David Laswell
     (...) I was aware of the Kiddiecraft connection, and that TLC bought all the remaining rights from them at some point, but I thought the original Automatic Binding Bricks were a legally licensed copy/variation of the Kiddiecraft bricks. If they (...) (15 years ago, 28-May-09, to lugnet.cad, FTX)

        Re: Looking for dimensions of LEGO bricks. —Anders Isaksson
   (...) YRW :-) In a book of LEGO history I read, it was explicitely stated that the original inch based measures were changed to mm. I don't remember which year, but it was a long time ago. The distance between two studs is 8 mm. (15 years ago, 25-May-09, to lugnet.cad)
   
        Re: Looking for dimensions of LEGO bricks. —Philippe Hurbain
   (...) I tried the experimental approach, built a long line of 23 x Technic beams 16 assembled with plates and measure the total length: 2937mm With 8mm distance between studs, the theoretical value is 2944mm, error is -0.23% With 5/16" distance (...) (15 years ago, 26-May-09, to lugnet.cad)
   
        Re: Looking for dimensions of LEGO bricks. —Anders Isaksson
   (...) I'm not at liberty to say too much, but I have actually looked at three real drawings of LEGO parts, and not even TLC seems to be sure what the dimensions should be - I've seen the distance between two studs dimensioned as 8 mm on one part and (...)

        Re: Looking for dimensions of LEGO bricks. —David Laswell
   (...) That much? Wow. I figured the distance between two studs should be closer to 3mm, since a LEGO tile is (in theory) 3.2mm thick, and it will sorta fit between two studs. Or were you refering to the center-to-center distance? Anyways, one thing (...) (15 years ago, 27-May-09, to lugnet.cad)
   
        Re: Looking for dimensions of LEGO bricks. —Anders Isaksson
   (...) Center-to-center, of course. The stud diameters differ by 0.028 between the drawings too, creating a diff of the gaps of 0.046 (but the length of the parts are exactly the same). (...) Well, the drawings are of parts, not molds (and the parts (...) (15 years ago, 27-May-09, to lugnet.cad)
