positive or negative rotation angle around the y-axis

I tried the following processing with ijcad2021 STD.Right hand coordinate system.

Draw a figure in the x>0,y>0 area on the 1.xy plane.
2. Rotate the figure -90 degrees around the y-axis using 3 drotate. As a result, the figure after rotation went to the y<0 area on the YZ plane.

When I asked ijcad's help center if the rotation angle was incorrectly positive or negative, the following response was received:
"Our IJCAD is designed to be highly compatible with AutoCAD.
The rotation and other commands are designed to work the same way as AutoCAD, so they may not be the same as you want."

Unfortunately, I don't have AutoCAD other than LT, so I can't check the operation.
This issue is about the definition of positive and negative Euler angles, and I do not think Autodesk has adopted such a specification that goes against the common sense of geometry.
So, I have a favor to ask of those who are reading this.If you have AutoCAD other than LT, could you please try to operate 1. and 2. above and let me know the results?
