Brief Background Information

I am B.Tech. (3rd year), Information Technology (IT) student of Guru Nanak Dev Engineering College, India. Proficient in writing code in C/C++, Python, bash scripting and recently also worked on Open-source Mathematical Software System (SageMath).

I also worked on Structure Information Modeling (SIM) and made a parser to store contents of STAAD PRO files into MySQL database. User can provide building specifications (for example) through web browser and at the back-end, FreeCAD macros use these input values to draw different views of the building on different drawing sheets. To support 3D rendering on the web browser, an option is provided to convert FreeCAD native file format (.FCStd) to WebGL format.

I also developed a Python script for AutoCAD to change the dimensions in a DXF file with a defined increment. Currently, I am working on code compliance on IFC files using parsing functionality of IfcOpenShell using Python.

Project Information

Project Title: Rebar Addon for FreeCAD

Brief Project Summary

My project is to create a rebar addon for Arch Workbench of FreeCAD to ease up the process of creating reinforcement in structural element. The main purpose of this project is to enable the user to create reinforcement through an easy and intuitive way. For this proposal, I will be considering rebaring systems for rectangular footing, pedestal, column, beam and slab.

Detailed Project Description

Existing system in FreeCAD

At present, the rebar functionality in FreeCAD is very limited and creating a reinforcement system is quite tedious. The current approach is followed by creating a sketch for the rebar profile and defining the required set of constraints. This becomes very time-consuming task when user has building model with several structural objects.


Proposed solution to the problem

To ease up the rebaring process in FreeCAD, an interactive addon will be developed where user will input the required data as per the design requirements and they will need not to draw rebars from the Sketcher workbench for creating reinforcement in the structural object.

The basic procedure to achieve this goal will as per the following points:

  1. The first step will begin in the Arch workbench by creating a structure from the “Create a Structure” tab, or alternatively the user may also create a sketch of the profile from Sketcher workbench and then extrude it to transform into the desired structure.

  2. Then the user will select the desired element or a number of elements of a same category.

  3. After selecting the element(s), user will click on rebar dropdown provided in Arch workbench. From dropdown, user will select the rebar shape. Upon selection, dialog box will pop-out with input fields specific to selected rebar. User can enter the input values in the input fields and finally submit with button click.
