| (...) Thanks for the link. I think I'll be able to use this in a number of places - there are several rubber bands wrapped around the stacks on top of the engine, and well as some around the chassis. I'm thinking I might also be able to simulate the (...) (22 years ago, 31-Dec-02, to lugnet.cad, lugnet.cad.mlcad)

| (...) Thanks for the link! I've downloaded the file, read through the readme.txt, and will definitely be using this. It is essentially exactly what I was looking for ... I'm sure I'll be able to simulate nearly all of the hoses, pipes, and conduits (...) (22 years ago, 31-Dec-02, to lugnet.cad, lugnet.cad.mlcad)

| (...) This page has a spreadsheet for modeling curved nets. Perhaps that might help with modeling string since the real nets are made of string? (URL) always have trouble finding that page because a google search for ldraw and net doesn't pick it (...) (22 years ago, 30-Dec-02, to lugnet.cad, lugnet.cad.mlcad)

| Hi Shaun, I have written a program called lsynth, which does many bendable things like: flex-system hoses, pneumatic hoses, flexibe axles, ribbed hose, electric and fiber optic cables. The program is called LSynth and is available (URL) I'm also (...) (22 years ago, 30-Dec-02, to lugnet.cad, lugnet.cad.mlcad)

| Hi All, I've been working diligently on LDrawing my Hudson 4-6-4 Steam Engine ((URL) and am finally running up against the seemingly impossible: Is there a way to modify pieces so that they bend and curve? So far, I've replaced bent flex-tubing with (...) (22 years ago, 30-Dec-02, to lugnet.cad, lugnet.cad.mlcad)

| (...) This sounds like a shortcut in the algorithm. If the bezier function is f(t), it does not have the property that |f(t) - f(t+d)| = c for all t, d given. I've corrected for this in my algorithm by using some simple optimization to find a (...) (22 years ago, 28-Dec-02, to lugnet.cad.mlcad)

| (...) Some progress - myself and a CAD expert mucked about a bit until we realised the obvious thing I was missing, the fact that the control point coordinates are specified relative to the end points and not in absolute coordinates! Jennifer (22 years ago, 28-Dec-02, to lugnet.cad.mlcad)

| (...) If memory serves me well, in Fredrik's Ldraw mode you specified the endpoints in terms of orientation as well as coordinates, stated the number of joints and it calculated the rest. Certainly a good system for many instances as that (...) (22 years ago, 27-Dec-02, to lugnet.cad.mlcad)
