Learning Information
1 – Aims
The objectives of this Rhinoceros and Grasshopper tutorial are as follows:
- Learning about a CAD software with great tools for 3D modeling.
- Knowing how to call the Rhinoceros plug-in to make parametric designs.
- Knowing the Grasshopper interface and the differences between a parameter and a component.
- Creating from simple shapes like a hexagon, to more complex geometries like a hyperboloid.
- To know an example of Grasshopper in the BIM methodology.
2 – Learning methodology
The teacher will briefly explain what Rhinoceros is and, a little more extended, Grasshopper; making sure the student understands what a parametric design is.
Students should read this tutorial before watching the videos.
Students will follow the steps shown in videos 1, 2 and 3.
Students will watch an application example in Video 4.
To assess the achievement of the practice, each student will write a report.
3 – Tutorial duration
The practice described in this tutorial will be carried out in a computer classroom.
It will last 4 teaching hours.
4 – Necessary teaching resources
Computer room with PCs with Internet access.
Required software: Rhinoceros, AutoCAD
Hardware required: Pcs
5 – Contents
5.1 – Introduction. What is Grasshopper?
5.2 – Parameters and components
5.3 – Example
5.4 – Audiovisuals
6 – Deliverables
To assess the achievement of the practice, students will write a report of 4 pages maximum.
In this report, the student will explain the steps taken in practice, the difficulties encountered and the decisions taken. The report will be illustrated with photographs, where for each video, there will be a comparison between the original model and another with different dimensions and parameters.
The student will have to answer and submit test questionnaire.
7 – What we have learned?
To create parametric designs in Grasshopper.
To export the design to the available formats (.dwg, .3ds, .pdf, .kmz, etc.).
To visualise the model in AutoCAD.
Implementation of the geometric model in a BIM model.
