    Thanks
    I am using opengl.

    There are 2 parts to the program.
    1. developing a library of concrete elements (columns, beams, plank, connection hardware etc.) using opengl.

    2. defining where they go.

    This in a replacement for conventional CAD! which is prone for errors resulting from a multiplicity of input points for a given item. (floor plan, excavations, wall sections and details);

    I layout a set of grids( support lines)
    select a level (1st, 2nd, 3rd etc floor, )
    place columns from the column library and locate them on grid intersections
    place beams from the beam library and locate them by their supporting columns
    place plank from the plank library and locate them by their supporting beams

    now, if a grid line is moved, the associated columns move, the beam location and spans change, the plank location and spans change.
    Now is a change levels, the column length changes etc.

    this is all done automatically. Sort of like a "solid modeler" which I had tried.

    Sorry to be so verbose, and I thank you for you patients.

    Hmm... honestly I don't see anything 3D in the second image you attached to the last post.

    All right you are getting to me. This is a database that defines the total structure. Any change here changes everything. I am going away for a couple of weeks and try out your recommendations from scratch

    Thanks again

    Regardless of what the data is meant for, it is displayed as 2D, therefore suits well with the Graphics View architecture.

  5. The following user says thank you to wysota for this useful post:
