 | | Rubber belts modelling —Philippe Hurbain
|
| | | I created these parts (with Marc Klein's spring2dat utility) to be able to model rubber belts in my Technic creations. This is my first part authoring, so be indulgent... (critics are welcome though!) There are DAT-files for 5 fragments of rubber (...) (22 years ago, 8-Mar-02, to lugnet.cad.dat.parts)

| | | | Hello Philippe, Looks nice to me but (no offense) aren't they normally rounded? Looks very edgy to me. At least all the rubber belts I owe have a round shape. Play well Carsten (...) (22 years ago, 9-Mar-02, to lugnet.cad.dat.parts)

|
| | | | Hi Carsten, You are right, rubber belts have a round section, while my models have a square one. The real reason is that I used spring2dat that create square section. An advantage is that there are less facets and anyway belts are so thin that it (...) (22 years ago, 9-Mar-02, to lugnet.cad.dat.parts)

| | | | I just uploaded a Rubber Belt Generator utility, that creates DAT files for rubber belts taut between two pulleys. The rubber belt generated can have a square section or a round one, using cylinder primitive. This utility is available from (URL) (...)

| | | | Hi Kyle, (...) ??? For pulleys in the horizontal plane it is easy to rotate the generated rubber belt 90°. Or do you mean something different ? Philo www.philohome.com (22 years ago, 26-Mar-02, to lugnet.cad.dat.parts)

| | | | (...) I was imprecise. I was thinking of pulleys that are rotated 90º in relation to each other. It would look something like this in plan. (sorry for this bad diagram) Ox- "O" = big pulley "x" = belt "-" = pulley rotated 90º Or here's a good (...) (22 years ago, 26-Mar-02, to lugnet.cad.dat.parts)

Yes, I think so too - though the two axis rotation of straight parts might not be so easy. (...) (22 years ago, 27-Mar-02, to lugnet.cad.dat.parts)
