★Why does the content shift when inserting other DWG drawings in ZWCAD

Issue:

As shown in the figure, the origin of the drawing frame file is located at its bottom-left corner.
However, when referencing this frame file in another drawing, there is an offset between its base point and the frame, instead of being at the original coordinate position.
Why does this happen?

Solution:

The base point of a referenced drawing defaults to the World Origin (0,0,0), but it can be customized.
You can use the BASE command to specify a specific reference base point.
If you find the base point of a referenced drawing is incorrect, simply open that source drawing and use the BASE command to redefine it to the correct location.
