   1) What is the use of the RIGIDHOSE command? I can’t seem to make it work. From it’s type I should think I had to use the LS00 constraint part, but nothing gets generated when I try it.

Instead of “RIGID HOSE”, use “FLEX SYSTEM HOSE”. They mean the same thing, but the second one actually works! Yes, you should always use the LS00 constraint part. In this case, 77.dat will be used to generate the hose which is just a short cylinder.

   2) Why do some gears not work with the CHAIN (and similar) command? In the case of the Crown Gear it simply means carefully selecting which one to use, but the 8 tooth gear is missing! Is there a way to ‘enable’ this part for LSynth?

The part numbers of some gears are hard coded into the software (if I understand correctly). There isn’t any way for you, the user, to add more. Those currently supported are the old light gray differential ring gear, the newer dark grey diff ring gear, the 16 tooth spur and clutch gears,the 24 tooth spur, clutch, and crown gears, the 40 tooth spur gear, and the outer ring gear of the old turntable top. LSynth is looking for these part numbers, but sometimes you can make a substitute. For example,there are 3 different types of 24 tooth crown, but only one works. If yours doesn’t work, try one of the others. Also note that the new turntable has the same number of teeth as the old, so you can synthesize a chain using the old one, then delete (or hide) it and put in the new turntable.

The 8 tooth pinion gear is really too small for the chain links to wrap around. Even the 16 tooth gear barely makes it. However, the 8 tooth pinion can sometimes be used as an idler with a small wrap angle like in this render I made. In this case, I put a hidden 24 tooth spur gear in which was tangent to the 8 tooth pinion. This gave me the right chain but you can’t see the gear I used to do it.

   3) I’ve read ‘rumours’ about a new version of LSynth. (although some are quite old). Would that version include the possibility of synthesising the new treads?

I’ve heard the same rumors, but no luck so far.

(...) Thanks, so it's not just me not being able to get it to work :-) A related question: I'd like to render a Fiber Optic cable like the one in the Spybotics sets which is quite a bit thicker than the ones that came with the FOS.

I'm trying to learn how to use LSynth and after reading the chapter about this tool in "Lego Software Power Tools" there are still a few things I can't seem to figure out. 1) What is the use of the RIGID_HOSE command? I can't seem to make it work. (...) (15 years ago, 26-Feb-09, to lugnet.cad)
