 | | Movement and friction —Barney Hilken
|
| | | Perhaps I should say that my interest in this is that I am involved in the project on the next-door website to develop an LDraw program for MacOS X, and I think connections should be built in from the start. I had a look at the LCD page on the LDraw (...) (22 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)

| | | | (...) For the time being, Barney, the problem is that if we will have a database at all. Lugnet.CAD.Dev was very enthusiastic when we presented the idea. All wonders endure three days, this was the very example, after the three days came silence. (...) (22 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)

| | | | | I was thinking of friction as a simple on/off property: connections with friction only move during construction, whereas connections without are free to move under gravity or inertia or other forces during animation of the final model. Is this too (...) (22 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)

| | | | | | | (...) Welcome in my brain, Barney: I was writing about gravity and inertia in this very hour. The approach you describe may be usable, but as for myself, I'm talking in the LMPL proposal about a tensile strength instead. I see some difference. (...)

| | | | | | | | (...) I agree. Although I called it friction, I didn't mean the true physical property. It seems to me that the difference between grey pins and black pins is structural in nature: they are different connectors from a builder's point of view. I (...)

The situations I'm thinking about are: 1. axles in technic bricks, which fit your "no friction" model; 2. the light grey low-friction pins, which could also fit the "no friction" model (with regard rotation); 3. the (...)

The obvious way to do this is to recognize the tube or enclosing box with their (...) (22 years ago, 11-Feb-02, to lugnet.cad.dev.lcd)
