Why the object disappears in plan?

Hi.I created a new furniture style from blocks.It can be displayed in 3D view and top view,but disappears in the varq plan.Can you find the reason?Thanks.

File?

@ArchiWood please provide a 3dm file with this error. Make sure the base point of the block used for the Plan representation is in the same position as the block for the Model representation.
