Enhancement of mechanism of P-Point selection

[rompik]

Hello Shing, Please, can you enhance mechanism of selection of P-Points while measuring distance between 2 elements which have P-Points (piping components and primitives). Currently, it is quite difficult to get correct selection of start and end P-Points.

I think it could be different options to define mode of selections. Currently, it could be mode for selecting only P-points or P-lines or screen point (it's already released).

Form for setup mode of selection can be called by dedicated icons from Status Bar (like in E3D)

Form itself can contain 3 check boxes for now: P-Point, P-Line( any pline w/out posibility to filter for current moment) or Screen Point.

I can try to develop such form, but I will only need name of core methods which I can use for setup mode of selection. It will allow saving your time for another tasks.

OK. Now there is a function PipeCad.PickPoint(int theMode), set theMode=1 can pick the vertex of model, this will be better. I will consider to add mode to pick P-Point.

Firstly try to implement some simple snap function, such as Midpoint, Centre point.
