CAD for APD1
Product Analysis, SolidWorks,
rapid prototyping and working prototypes

2014 Toolbrandx 800Px

This is a five-week course, and will consist of lectures, individual instruction, product design, model building of a working prototype and a presentation.Most of the work will be done individually in the Top PC lab or by your work tables on your own computers. The CAD course will be run by Tomas Lindehell

The course contains of the two following sections:

1) SolidWorks course (Approx. 1,5 weeks)

The first weeks consist of a SolidWorks course based on differentiated tutoring with a number of small exercises. For experienced users, there will be the possibility of working with new methods and parametric modelling. During the first half of the fourth week you will get support when you should prepare your files for rapid prototyping. Tomas Lindehell will be teaching these courses. (See below for details).

2) Product analysis / Theme exercise (Approx. 2,5 weeks)

This section is divided into three phases:

2.1: Phase one concerns product analysis where a number of products are disassembled and analysed. After this you will all be given your own product to work with. The different production methods and materials of this main product should be documented in the final presentation together with full-scale drawings of its various internal parts and components in SolidWorks - This can be done as a team.

2.2: Phase two will be carried out individually. Here you will be asked to create a new design based on the given product and the theme exercise. Your new design should be build in SolidWorks with the purpose of creating files for prototype production using Rapid Prototyping (RPT).The theme exercise for your new product design will be handed-out on the first day of the course!

2.3: Phase three involves the finishing of the model and assembling with the original product's components in order to create a full-functioning prototype. This phase ends with a presentation and evaluation.

Form of tuition

Tuition is in the form of lectures and practical training under the supervision of tutor. In the computer lab, exercises will be carried out under the guidance of an authorized teacher. All sections in the course are obligatory.

Examination form and marks

Examination is in the form of individual practical test and presentation of results of the given exercises at school.

2017-PM-Course -Brief -8In order to obtain credit for the course, all sections and assignments must be successfully completed. Students receive a mark of either Pass or Fail for each assignment and section. For those students who do not receive a mark of pass, another opportunity is provided to pass the assignment or examination after a period of time. Presentation must be done in person at the school premises.

Rik's solidworks settings!

Rik says

These are the most important shortcuts i would say
 

P = perspective
V = orientation
F = zoom to fit
Z = zoom to area

N = normal to

R = rotate

Spacebar = pan

L = line

S = Shortcut bar

Suggested websites for advanced CAID tutorials:(Recommended by previous APD students)

www.dimontegroup.com/Tutorials/SolidWorks_Tutorials.htm
- "DiMonte group gets to some advanced SolidWorks surfaces tools, which basically tutors designerson how to recreate what they do in Alias, but in SolidWorks (start tutorials from bottom up)."

www.productdesignforums.com
- Shows how to surface model a mouse. You need to sign up for the website.

Rhino and SolidWorks   rhino_works_us.pdf
- Here's a Rhino3D 'whitepaper' on how to use it with Solidworks, but it's quite similar to use withAlias (Except Rhino opens natively in Solidworks and vice-versa, while Alias does not, so STEPformat would be used instead)."

www.rhino3d.com/3/stlrepair.zip
- Here's a good rapid prototype file fixing tutorial in Rhino. It explains Rhino tools and strategiesfor repairing non-watertight models. Similar (and some more powerful) tools exist in Alias (ask Tomas L.). Of course SolidWorks does not need that as it will not export open STL files, and as the name implies the work is supposed to be with Solids.

Found some other really good videos on YouTube, looks like it really is pretty easy to do some complex surfacing.
