Normally, the program assumes all coordinates to be relative to the current UCS. The following functions convert points between UCS and WCS.
Converts point p1 expressed in the WCS to the current UCS.
Converts point p1 expressed in the current UCS to the WCS.
You can use w2u to find the WCS origin in terms of the current UCS:
w2u([0,0,0])
The following functions filter the X, Y, and Z components of a point or vector.

|
xzof(p1) |
X and Z components of a point; Y component is set to 0.0 |
|
yzof(p1) |
Y and Z components of a point; X component is set to 0.0 |
|
xof(p1) |
X component of a point; Y and Z components are set to 0.0 |
|
yof(p1) |
Y component of a point; X and Z components are set to 0.0 |
|
zof(p1) |
Z component of a point; X and Y components are set to 0.0 |
|
rxof(p1) |
X component of a point |
|
ryof(p1) |
Y component of a point |
|
rzof(p1) |
Z component of a point |
The following example provides the Z component of a point expressed in spherical coordinates:
zof([2<45<45])
The following example provides a point whose X and Y coordinate values are taken from point a and the Z coordinate value from point b:
xyof(a)+zof(b)
