In Assembly, I want to implement selection where user can enter selection mode and can select either from model tree or from graphical area by drawing box. Currently non of the filters/options suffice this behavior. If I use "part" filter it doesn't allow me to select sub-assemblies from model tree. If I use "prt_or_asm" filter it allows me to select sub-assemblies but when I want to select a part from graphical area, it unnecessarily selects its parent assembly also as per design. Hence I am not able to provide user the exact solution. If you can provide an option that ProSelect will be able to select assemblies & parts from model tree and only parts from graphical area, that will be great.
