CAD Software

This repository hosts the Mathematical Model, Functional Model, Design Documentation & the source code to the 3D CAD Software for Development in Engineering Drawing.
This tool is made as a part of COP290 course under Prof. Subhashish Bannerjee.

Aim

We are going to design and implement a Software Package for Engineering drawing that shall be described and portrayed in a series of five steps to finely work out the design, analysis and the modelling.

The package will have the following functionalities:

1. We will be able to interactively input or read from a file either • An isometric drawing and a 3D object model • Projections onto any cross section
2. For a given 3D model description, the software will be able to generate projections onto the three orthographic planes.
3. Given two or more projections, we will be able to interactively re-construct the 3D model of the object and produce the isometric view along any view direction.

Functionalities

1. Read/Open 2D/3D model from files.
2. Save 2D/3D model in file.
3. Implicit conversion from 2D file[Projections] to 3D.

Project Description

Main Classes and UI are in src/ folder [Documented in docs]
Math Classes are the conceptual classes. [Documented in the subfolder]

Following is the description of the directories:

1. docs : Contains the html, latex, xml documentation of the structure of the software in the respective formats.
   
2. models : Contains the description of mathematics used for building the software and the functional model containing the StarUML structure and the design interface of the software.
   
3. src : Main files containing all the software files including the .h and .cpp files.

Platform compatibility

Built and tested on Ubuntu-16.04.

Technologies Used

1. QT : Cross-platform application framework that is used for developing application software.
2. Open-GL : Cross-language, cross-platform application programming interface for rendering 2D and 3D vector graphics.
3. C++ std-11 : General-purpose programming language.

Compilation and Execution Instructions

Following are the instructions to run the application software:

1. Install the dependencies QT, OpenGL, GCC with std-11 support

2. Clone

$ git clone https://github.com/udit01/qGL.git
$ cd qGL

3. Build [See that your anaconda or other paths don't interfere with the paths required by this makefile]

$ cd build && mkdir build
$ qmake ../src/CadSoftware.pro

4. Make

$ make
$ make clean # OPTIONAL #for removing object files after make

5. To execute, run

$ ./CadSoftware
