>> This routine defines a local coordinate system to be in effect until
|
|
another coordinate system is defined or the normal coordinate system is reset.
|
|
The new coordinate system is defined by specifying an origin, a point on the
|
|
new x-z plane and a point on the new z-axis. These points are specified in the
|
|
normal coordinate system. The options available in iopt are:
|
|
|
|
>>
|
|
|
|
>>> **define** define a new local coordinate system
|
|
|
|
**normal** return to the normal coordinate system
|
|
**save** save the current coordinate system for recall
|
|
**restore** recall the last saved coordinate system

|
|
|
|
where x0,y0,z0 is the location of the new origin, xx,xy,xz is a point on the
|
|
new x-z plane and zx,zy,zz is a point on the new z-axis. These points are
|
|
defined with the normal coordinate system, and used only with the **define**
|
|
option.
