那也就是说无法用vla-get-activexucs取出世界坐标系和用vla-get-activexucs强制把坐标系设为世界坐标系， ...

If you try to get the active UCS value when the current UCS is unsaved, an error will occur. It is recommended that you confirm that the value of the UCSNAME system variable is not empty before you get the active UCS value. Alternatively, you can add a new UCS object and set it to active before getting the active UCS value.
