Coordinate Systems In Cad

This section introduces essential coordinate systems used in CAD, including absolute, relative, and polar coordinates.

Absolute Coordinate System

The Absolute Coordinate System in CAD allows users to specify points using fixed coordinates relative to an origin.

Relative Coordinate System

The Relative Coordinate System allows users to specify coordinates based on the last defined point, enhancing drafting flexibility in CAD.

Polar Coordinates

Polar coordinates provide a method for defining points based on distance and angle, beneficial for inclined line drafting.

Basic Drafting Commands

This section outlines fundamental drafting commands in CAD, essential for creating and modifying designs in civil engineering.

Line Command

The Line Command in CAD enables users to draw straight lines between specified points, forming the basis for drafting in engineering design.

Circle Command

The Circle Command in CAD enables users to efficiently create circles by defining a center point and a radius or diameter.

Rectangle Command

The Rectangle command in CAD is used to draw rectangles by specifying two opposite corners, providing a simple and efficient way to create rectangular shapes.

Trim And Extend

The Trim and Extend commands are essential tools in CAD for modifying drawn objects by cutting away unwanted segments or extending them to meet boundaries.

Offset And Mirror

The Offset and Mirror commands in CAD allow for efficient duplication and arrangement of design elements in architectural drawings.
