Controls

CAD .NET provides users with the control elements inherited from Windows Forms to display CAD drawings. Usually such elements are located at Windows Form but they can also be located at the WPF page. If you need an ASP .NET based Web Control, it can be provided additionally. See Web CAD SDK.

The CADPictureBox class is the basic implementation of the control element for displaying vector drawings. Visually CADPictureBox includes only area for drawing visualization and can be extended by the necessary control elements in the project under development. EditorDemo is an example of the project using CADPictureBox.

The CADEditorControl class includes implementation of the required event and settings handlers. To start working with it it is enough to place such a control element in the form. CADEditorControl includes panning, zooming, visual entity selection as well as allows using such features as visual entity creating, visual editing with the help of markers and the Properties window, snap, grid and ortho modes. The EditorControl demo shows how to use this control element.

Deployment in CNC Machines

CAD .NET can be used for development of the software that prepares data for CNC machines. DXF format supported by the library is one of the most frequently used file formats for processing two-dimensional surfaces. Access to drawings data enables users to get all the information necessary for processing.

The library also makes it possible to transform entities including conversion of the source drawing texts into polylines with high precision of curved line segment. For example such a feature can be useful for laser processing.
