Truck Loading Software

I need some software for creating truck loading layouts. Simply put, I need to place multiple 3D shapes onto a rectangular object. (the rectangular object represents a 48'-0" flatbed trailer or a 48'-0" step deck trailer) 1. Enable the user to create multiple 3D objects with specific dimensions. - There would be 5 groups of objects (square, rectangle, triangle, 90'triangle and trapezoid) from which I could create custom sized objects from. - be able to change the color of each individual object - label each 3D object and show the label on all screen views and printouts (each labelled 3d object would have a list of materials associated with it) 2. I need to be able to drag and drop multiple 3D objects on to an object representing a truck trailer. - I must have the ability to flip or rotate each object - I must be able to place the objects on the trailer into exact position with the mouse or keyboard. (within inches) - No two objects can overlap or occupy the same space. - Objects can be stackable (a square could sit on top of a square, part of a triangle could sit on part of a rectangle etc) 3. I must be able to load the trailer and view the trailer three-dimensionally. - zoom in and out and view the trailer with the objects on it from any angle or distance. 4. I need the program to tell me (in real time) how wide, high and long the load is compared to the trailer dimensions. 5. Save each completed trailer load with a user defined filename. 6. Print 4 graphic load plans (left view, right view, front view and rear view) with the object label shown on each object and a list of materials associated with each object placed somewhere else on the output. Most loads created from this software would have a combination of: - lifts of plywood, lumber etc. (rectangle) and roof truss packages (triangle, 90' triangle and trapezoid). Here are a couple of web sites that will give you a general idea of what I am trying to accomplish BUT THEY HAVE TOO MANY FEATURES THAT I DO NOT REQUIRE and one main feature that I do require which is to create custom size objects (mainly for the roof truss packages) [login to view URL] [login to view URL] Please specify what programing language you would use. I do want to keep this as simple and easy to use as possible. I am not looking for "Bells and Whistles" at this point. Price is the main factor and will determine if I go ahead with this project. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Win98, Me, XP.
