ImportInstance.ByGeometry with no base level

I want to create a solid with dynamo and then place that solid in the correct position (with no level, only the offset).

The created solid appears to look in the correct position, but when the command ImportInstance.ByGeometry runs the solid instance moves to another level.

got a solution!
Create a new level at 0 and then set the parameter “Work Plane” to that new level.
