Problem with obtaining correct bounding box

 Hello All,

I am working on one of the module where I need to obtain bounding box for some of the components of PCB using skill script.

I have already written skill script to obtain bounding box for selected components.

I am using  "axlDBGetExtents" function for this.

However, I am facing one problem with this method.

Problem:

Bounding boxes obtained using this function are larger than what I need.

For my purpose, I need bounding box prefereably (or I would say ideally) of the size of top surface of the component.

My Current Method:

I have used "t" as second argument for axlDBGetExtents(id t) function.

According to documentation,  by using "t" as a second argument, bounding box only for visible parts of component is selected.

I am controlling visibility by using "Display->Color/Visibility" option.

I am choosing to disable all options except "Package Geometry -> Assembly_Top & Display_Top".

Please let me know if I am doing something wrong here as I have started using this software only a month ago.

Any suggestions that would help me in resolving this problem are welcome.
