ARCH 655 Parametric Modeling in Design

Final Project - Algorithms and Scripting for Parametric Design

Due: 4/28, Wednesday 10:00PM

Weight: 50%


Project Requirements

You are expected to create more powerful model definition and better defined parametric designs, with the use of the two advanced methods: (1) algorithms, especially Genetic Algorithm; and/or (2) scripting that can expend the capability of existing tools and help you create your own algorithms.

This project can be built based on Project 1, with improvement of existing models, and new design, data, content, and/or methods added. You can also choose to build this project on another building design/model of your own, instead of Project 1.

Your tasks include:

1. Homework and Tutorials  (15 pts)

Complete all the exercises assigned for the second phase. Follow the deadlines and submission procedures for each exercise. The completeness of the tutorials and on time submission will count toward part of the final grade of this project.

2. Parametric Modeling through Algorithms and/or Scripting: develop your parametric modeling definition using the techniques we have studied in the course. You may improve your Project 1 to implement new ideas. (45 pts.)

Examples are:

2.1. Using Genetic Algorithm to optimize your design.

2.2. Using external data (e.g. through Excel) to drive your model.

2.3. Use scripting to implement conditional statements (IF Then) for different design options.

2.4. Use scripting to loop and create patterns.

2.5. Use scripting and/or other tools to link between parametric geometry (in Rhino/Grasshopper) and BIM (in Revit).

2.6. Use Parametric Design Patterns to add components to your models.

2.7. Other applications (think creatively).

3. Document your project (20 pts). Save screenshots of the models and data display, including views, and running process, etc. Publish the documentation on your blog.

In addition , you are expected to create a movie (up to 4 minutes in length) by by capturing your computer screen that demonstrates your models, parametric design, and user interaction with your voiceover as narrative. You can use Camtasia (about $15) or other software to make and edit the movie. Upload the movie to your Blog (making sure the video quality is high).

Suggested resolution: 1024x768 or 1280x960 pixels. Suggested format: Flash (in a web page), MP4, WMV. Clear images and sound are expected.

Here's instruction about posting videos on Blogger

4. Final presentation (10 pts)

Please make sure your movie on your blog is ready to be played before we start the presentation.

Please also submit your movie with other files to eCampus.

5. Submission

Project submission includes the following four items.

5.1 Application submission to eCampus.tamu.edu

Project folder name Project2_Final_YourFirstname_YourLastname
Files in the folder Models, definitions, images, screenshots of the models and data display, including model views, datab views, and running process, instructions about how to run your application, presentation movie, etc., organized into good a folder structure.

File to submit Project2_Final_YourFirstname_YourLastname.zip
Submit to http://eCampus.tamu.edu/
ARCH655->Content->Project 2_Final


5.2. Submission to the Web

Create a web blog page containing your Final Project description, screenshots, presentation movie, and links to other pages. Your name and "ARCH655 Final Project" should appear on your blog page. Check the following page and click your project2 thumbnail to confirm that the link is pointing to your blog.


Web Your Blog page on Blogger.com
Items on the page

1. Description/documentation
2. Images/screenshots
3. Presentation movie

Embed images and the movie into the text, and make the images clickable to show the images in their original size.

5.3 Submission of your project thumbnail to eCampus: http://ecampus.tamu.edu

Create a 160x120 pixel thumbnail image based on your exterior rendering. Save it as Project2_YourFirstname_YourLastname.jpg, and upload it to http://ecampus.tamu.edu

The thumbnail will appear on the following page after it is uploaded by the instructor:

File Project2_YourFirstname_YourLastname.jpg
Submit to

ARCH655->Content->Project 2_Thumbnail

Check your web page and links from

Make sure everything works by the due time. (Thumbnails will be displayed before presentation.)


Understand and experience advanced, algorithm- and scripting-based parametric modeling methods.


Your work will be judged on its technical quality and on its visual content.

6. About Exceptional and Extra Work (10 pts):

As stated in Syllabus, a project is given 90% as a basis for “Satisfactory work, meet standards”. Based on project requirements, errors will cause reduction of points and exceptional or extra work is awarded with extra points.

Examples of Exceptional and Extra Work:

1. A very well defined, advanced parametric model utilizing techniques that we learned in class, with high quality documentation documenting the background, design ideas, and implementation.

2. Using techniques/tools that we didn't learn in class together with Rhino/Grasshopper to create your models, with excellent explanation and documentation.

3. Creative use of Parametric Design Patterns in the project.

4. Highly creative design and modeling.

7. See Students page for previous projects and sample movies
