Build a model that shows the possible gear ratios for gears contained in the NXT kit. You can even mail it to me if you like, at this address. You need not worry about filesize. > And the hinge tool does work on Technic elements, and building triangular > structures is difficult but possible. As an example, see my rover here: Yes I know it works on Technic elements but the annoying part is that if you have a friction pin in the way of where you want to rotate or align to, you have to move that out of the way first, rotate your part so it lines up properly, and then you have to put that friction pin back in again. It would be more sensible for the LDD software to test if you can line up the beam on friction pins first, during the rotation phase, and signal if that is indeed possible. Another problem is that objects sometimes will not rotate to the precise angle required on bent beams. Which means you've got to get it close enough for the software to want to pop the two assemblies or beams together. http://cache.lego.com/media/nxtlog/fa55a01c-aac4-4cdf-9fdb-400c6e41f803/rover.lxf http://cache.lego.com/media/nxtlog/2725d0e8-5945-4af3-998a-4ea989dc03e0/200x200/rover.jpg An excellent model, however, the site indicated that it didn't want to serve me that page. I found it was due to that you have both the .lxf file and the .jpg file embedded in the same URL, which the site does not understand when my browser sends it as a http get request. Above I have fixed them so they appear on separate lines and hopefully click properly. Cheers ... Geoffrey Hyde

(...) Granted, meshing gears is awful. You have to place the gears on axles with space between them, rotate one with hinge tool until they could match, then move the rotated gear and axle in meshing position. And trying to modify a gear ration in an (...) (17 years ago, 16-Sep-07, to lugnet.cad.ldd, lugnet.robotics.nxt)

(...) Those style links are created and understood by the web interface to insert in-line links and image. The use of <> however "broke" and confused all the NNTP clients so we see it string together. ThunderBird handled it well enough and split it (...) (17 years ago, 17-Sep-07, to lugnet.cad.ldd)

Hi Geoffrey, I think you are a bit harsh about Technic/NXT building with LDD. I agree with you that it is not perfect, and it is sometime painful to do what you want, but it is possible to virtually build things with it. And the hinge tool does work (...)
