Aim

Design and implement a software package for Engineering drawing with the following functionalities:

• We should be able to interactively input or read from a file either
  i) an isometric drawing and a 3D object model or
  ii) projections on to any cross section.
  
• Given the 3D model description we should be able to generate projections on to any cross section or cutting plane.
  
• Given two or more projections we should be able to interactively recover the 3D description and produce an isometric drawing from any view direction.
  

How to use:

Input Format:

• To Draw the 3d object:
  

  • Press n.
    
  • Press 'u' for positive x-axis and 'j' for negative x-axis.
    
  • Press 'i' for positive y-axis and 'k' for negative y-axis.
    
  • Press 'o' for positive z-axis and 'l' for negative z-axis.
    

• Using text file:
  

  • To generate projections from 3d object:
    
    • First line gives type i.e, zero for 3d to 2d
      
    • Next line gives n, number of shapes.
      
    • Next n lines gives the points for basic shapes in the following format:
      Basic shapes include point(1), line(2), triangle(3) and quadrilateral(4)
      First the number of points according to the shape and then the x,y,z coordinates.
      E.g.- 3 (1,1,0) (0,0,0) (0,1,0) //This is for a triangle
      
  • To generate 3d object from 2d projections:
    
    • First line gives type i.e., one for 2d to 3d
      
    • Next line gives n, number of points for top projections.
      
    • Next n lines gives the points (x,y,z coordinates with spaces in between them)
      
    • Next line contains e, number of the edges in top projection.
      
    • Next e line should contain 2 integers, i, j, denoting an edge between vertex i and vertex j as per the order of input of vertices (order starting from 0)
      

• Executing the code:
  

  cd Cop290/codes/src/
  

  make
  

  Without any file
  

  ./cadmake 
  

  With File
  

  ./cadmake <input.txt>
  

•   Additional Commands: </br>
    't' to save.
    'w' to zoom out.
    's' to zoom in. 
    Arrow keys to rotate.
    'x' and 'y' to reset x and y rotation respectively.
