Creating a simple CAD program in Python

Creating a simple CAD program involves a significant amount of code and typically requires the use of graphical libraries to handle drawing and user interaction. Python has several libraries that can be used for GUI (Graphical User Interface) development, and one popular choice is Tkinter. Below is a basic example of a simple CAD program using Tkinter in Python.

import tkinter as tk

class CADProgram:
    def __init__(self, root):
        self.root = root
        self.root.title("Simple CAD Program")

        self.canvas = tk.Canvas(root, width=800, height=600, bg="white")
        self.canvas.pack()

        self.canvas.bind("<B1-Motion>", self.draw)
        self.canvas.bind("<ButtonRelease-1>", self.reset)

        self.start_x = None
        self.start_y = None

    def draw(self, event):
        x, y = event.x, event.y
        if self.start_x is not None and self.start_y is not None:
            self.canvas.create_line(self.start_x, self.start_y, x, y, width=2)
        self.start_x, self.start_y = x, y

    def reset(self, event):
        self.start_x, self.start_y = None, None

if __name__ == "__main__":
    root = tk.Tk()
    app = CADProgram(root)
    root.mainloop()

This code sets up a basic Tkinter application with a canvas where users can draw lines by clicking and dragging the mouse. The draw method is called when the mouse is moved, and it creates lines on the canvas. The reset method is called when the mouse button is released, resetting the starting point for drawing.

Keep in mind that this is a very basic example, and a full-featured CAD program would require additional functionality such as the ability to draw various shapes, pan and zoom, save and load drawings, and more. Developing a comprehensive CAD program is a complex task that may involve additional libraries and more advanced GUI frameworks.
