Co-ordinate Input Methods
Co-ordinate Input Methods in AutoCAD Programming
Introduction
Co-ordinate input methods are crucial in AutoCAD programming as they provide a way to precisely control the placement of objects in a drawing. Understanding these methods is fundamental to efficient and accurate drafting.
Key Concepts and Principles
Directive Co-ordinate Input Method
The directive co-ordinate input method allows you to specify a point by moving a certain distance from the current position in a specified direction. The syntax is `@distance
Summary
Co-ordinate input methods in AutoCAD programming allow for precise control over object placement in a drawing. These methods include the directive, absolute, relative, and polar co-ordinate input methods. While they offer efficient and accurate drafting, they can be challenging for beginners and prone to errors if co-ordinates are input incorrectly.
Analogy
Think of co-ordinate input methods like a GPS system. The absolute co-ordinate input method is like entering an exact address, the relative co-ordinate input method is like saying 'move 200 meters north from here', and the polar co-ordinate input method is like saying 'move 200 meters in the direction of 30 degrees'.
