When using the mouse wheel to zoom in or out, the screen should zoom in where the cursor is. RAM is the only software I have ever used that zooms in and out to a random, arbitrary, undefined point and it is very difficult to zoom in close to objects. Very frustrating and an easy fix, not sure why RAM is like this.
Let us investigate what's possible with the current graphics. Are you mostly concerned with the plan behavior in Modeler and Ram Steel Beam, or in the 3D view environment?
