Translate that point from one coordinate system to another.
This function translates (moves) a point from one to another coordinate system.
The point argument is a 3-D point in list format. The meaning of this argument depends on the setting of flag.
The from argument describes the current coordinate system:
| Code | Coordinate system |
|---|---|
| 0 | World coordinate system (WCS). |
| 1 | Current user-defined coordinate system (UCS). |
| 2 | Display coordinate system ( DCS) of current viewport-with code 0 or 1 |
| DCS of current model space viewport-with code 3. | |
| 3 | Paper space DCS. |
| Flag | Meaning |
|---|---|
| T | 3D displacement. |
| nil | 3D point. |
