Application is intended to create a 2D canvas from interactive, creating the vector graphics


Graphic applications which make the backbone for CAD/CAM/GIS applications need to have a canvas or view on which all the graphic elements are rendered. Any complex model in CAD/CAM/GIS applications is composed of basic graphic elements such as lines, arc, circle, ellipse, rectangles, polylines, polygons…etc.

The complex models are easily created by performing the simple operations on the graphic elements, and these basic editing features include copy, cut, paste, move, delete, scale, mirror.

Mapview is an attempt to create a C# component that can be used to create and edit the graphic elements interactively.


Mapview control is a C# component, which allows the user to create various types of vector graphical elements and which will be created and edited interactively.

To avoid this inconvenience, this implementation is logically divided to geometrical model and view. When you're editing objects inside the Mapview, geometrical model (presented in “real world” coordinates) is changing and the view (client coordinates) stays the same, and when you rescale and scroll the Mapview, the geometrical model stays unchanged.

Mapview model could have several views showing different parts of the model. All views are updated automatically when the model changes, it means that if you moving or editing shape in one of the views you will see changes in others.

Using Mapview

The sample code is having the detailed description about using the application. This is initial version of the control and some of the functionality is yet to be implemented.

Using the code

Enthusiastic users are encouraged to take the code implement/modify/fine tune the code wherever required.

Points of Interest

I would like to make an efficient FREE CAD/GIS graphic engine in .NET using C#. So, that the users need not depend on the proprietary software to make the applications. This is the first step in that direction.
