Challenge

ATLAS design challenge

During the preparation week, we are organizing an ATLAS-wide one-day design challenge. One of the ideas of such a challenge is to promote vertical integration within the college; hence, all classes are invited to participate.

The theme of this year's design challenge is

Future of design: Freeform & Collaborative

Lizabeth Arum from Ultimaker is joining us. As an Education Community Manager, she has a track record that involves a.o. educational practices for freeform design (for 3D printing). At the start of the day, she will give an introduction into freeform modelling using Autodesk FUSION 360 modeling environment. You will be introduced to the sculpting mode, the patch environment, and how to work collaboratively on one design.

After that you will work in small groups on a specific design challenge, namely Design of a smart seat supporting multiple parts of the body in which you can practice with the FUSION 360 modelling environment in a team setting. Details of the design challenge will be given on Monday; however, to make an effective start it is important to collect a number of reference images (jpeg/png/etc.) of possible seats beforehand. For instance:

At the end of the day, all groups present their results to each other and to a jury.

To prepare yourselves for the day, we would ask you to:

• Install the FUSION 360 software from the Autodesk website on your laptop beforehand: http://www.autodesk.com/products/fusion-360/free-trial or Fusion 360 for education
• Gather a number of reference images (jpeg/png) of possible seats as mentioned above. You can use these as a starting point for your design in the software environment.

Time table for Monday January 30th (RA2520)

• 10.30h Start with FUSION 360 introduction by Lizabeth Arum
• ~12.00h Start of group work (you are free to plan your activities during this part)
• 16.30h Presentation of group results (including jury feedback)
• 17.30h End of the day

Design of a smart seat supporting multiple parts of the body

After the FUSION 360 introduction, you will work in small groups on a specific design challenge, namely Design of a smart seat supporting multiple parts of the body in which you can practice with the FUSION 360 modelling environment in a team setting.

The challenge is to think of a novel idea to make a seat smart(er); i.e. incorporating intelligence through sensors and/or actuators. You are free to decide upon the type of seat and its purpose; however, the seat should support multiple parts of the body.

You should give shape and present your idea using the FUSION 360 modelling environment. Concerning FUSION 360, you are encouraged to make valuable use of the techniques introduced.

Evaluation criteria

• Application of Fusion 360 techniques
• Novelty of concept idea
• Quality of presentation
• Comfort Level

Sculpting in Fusion 360: The Sculpt Workspace

Sculpting in Fusion 360 allows for the intuitive freeform creation of organic solid bodies and surfaces by leveraging the T-Splines technology. You can explore forms by pressing and pulling on subdivided surfaces. Sculpted forms are easily converted to solid bodies, and can be used in conjunction with Fusion 360's solid modeling commands.

One of the main advantages of T-Splines is the ability to add detail only where necessary - a single T-Spline surface can be smooth, while still having areas of high detail and remaining easy to manipulate. T-Splines allows designers to: Add detail only where necessary
Create non-rectangular topology
Easily edit complex freeform models
Maintain NURBS compatibility

When in the Sculpt Workspace you have access to the Gizmo, which lets you manipulate vertices, edges and faces. The Gizmo has this name because twenty years ago 3D Studio Max called this tool the Gizmo.

The Gizmo allows you to translate a face, vertex, edge along an axis or a plane, and lets you scale and rotate your selection. If you double click on a single edge, Fusion will select the whole chain, or tangential lines.

When working in the Sculpt environment, the only option undo a step is to go back through through the last twenty or so steps. The number of undos is based on your RAM and how much cache space is left.

In addition to extruding and revolving, you can also generate a T-Spline body by sweeping a profile. Sweeping is commonly done with circles, however any closed shape can be used in conjunction with a line in a sweep to produce a solid.

Collaboration

On left side, open the Data Panel. Collaboration starts with fact that it is cloud based software. You don't store your files locally. Files are saved on Autodesk servers at Amazon Web Services, so you'll always be able to see your files.

Fusion allows you to add people to a project. Once invited, your invitee will get an email. They can then see your project in their data panel. You might be asking: Does that mean anyone can edit, download and delete your files? The answer would be yes.

Fusion is working on preventing that, but at the moment you either have full access to a project or you don't have access, so be careful.

Two people can open the same file at the same time, but they will be working on different instances of the file. Once on person saves the file, the other person will see that they are not working on the most recent version. If they update the file, they will lose everything they have just done and see what their collaborator has done. If you save first, then your version becomes the most recent.

A new version is created on the server in Seattle Washington. The collaborator will get a notification that they are not working on the most recent version, that it is out of date. If you update you will create a new version with all the changes made in the last version, but you will lose what you were working on.

Companies pay PDM systems, basically a Data management systems 10-15K per person a month. Fusion offers this functionality for free. The data will always exist on the server—this is beneficaial. Large companies might pay millions for this functionality. All this functionality is taken care of from the cloud.

Ability to add comments. Click on an aspect of the model, take a photo, write a comment.

Information: who is using the file, who is doing what, versions A lot of viewing and collaboration capabilities that are not in Fusion 360. In the data panel, click on the name of the project ( use firefox or chrome) and you will be taken to myhub.autodesk360.com All the projects are now viewable in a browser.

• All the files
• Activity-whats going on
• overview-information, thumbnail. the thumbnail allows you to share what your project looks like with someone who does not have the same modeling application as you. So if someone does not have fusion, they can still access the file as long as they have been invited

You are able to view versions and notes. At any point you can select one of the previous versions and promote it to the most recent version. Handy if new changes are rejected

Viewer

Viewer is a powerful option. Works with any browser. works with almost almost all Autodesk CAD formats and all standard formats, SolidEdge, ProE and some Solidworks files.

• Explode
• Mark up
• Notes, add comments

If someone makes a change in the current file while you are in the Viewer, you will not see the changes until you go back into the project and look at the Overview.

Properties

Share your files Calendars—set up due dates You can put any files in the project and they will be usable in the viewer. So if you upload a word doc and your collaborator does not have Word, they will still be able to read it in the viewer.
