How to modify the layer of a line

[yingyue4008]

After replacing the line layer, the lines have reached layer 0，

I don't know where the layer handle on the line is recorded，is dwg.object[i].tio.entity->layer or dwg.object[i].tio.object->tio.LAYER->xref？

How do I replace the layer on the line？

It's dwg.object[i].tio.entity->layer, which is a handle pointing to the layer.

Thank you very much，Can be set.
