Hi, supports both full - and partial-inclusion area selection?

How do I implement this feature？

Hello @gades,

The [SelectAreaOperator](https://docs.techsoft3d.com/hps/latest/api_ref/cpp/class_h_p_s_1_1_select_area_operator.html#selectareaoperator) does not have the option to limit selection to only **fully** enclosed geometry. Rather, selection is set up for partial inclusion by the rectangle area.

Thanks,  
Tino
