This 1.5-point course is in the third year of Bacheler and is a
part of the course Designpresentation
Used CAD programs are Rhino, Autodesk Alias Automotive, Mudbox,
Meshmixer, ReMake, Netfabb, Meshlab and SolidWorks. (123D Catch can
not be used anymore)
Goal and contents
Students are given training in:
- "Catching" real life object into 3D digital computer models.
CAID on a wider level in order to be able to create advanced 3D
- Knowledge of making physical prototypes with CNC-milling
machines and Rapid Prototyping machines.
The aim is to give a knowledge of how several CAD
tools is used together for the above
The difference between different
- Meshes, Polygons
Understand when and why these 3D-format are
The different modeling paths available to
maximize modeling efficiency.
3D-measuring technologies as:
- Laser scanning
- Structured light scanning
- Photo "scanning"
- Measuring arm
Knowledge about the softwares role in the
Importens of construction tolerances and linear
Clean exporting of your model for prototype
Understand the process of
data transfer as it relates to their designs to other CAD
systems. An overview of the merits and limitations of various file
transfer formats (i.e.: IGES, STEP, STL, OBJ
etc.), tips and traps will be provided
Prepare models for successful rapid
Completion of Rhino course (BA2)
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 authorized teacher. All sections
in the course are obligatory.
Examination form and marks
Examination is in the form of individual practical tests
and presentation of results of the given exercises at the
In 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
Exercises to be completed
1. Export Milling
files for the
bigger Pro milling machines, STEP or IGES
Preparation of files in Rhino (in Swedish)
Preparation of files
in SolidWorks (in Swedish)
- Make a SIMPLE 3D-model. With maxium
size 110x80 Height
- One STEP file
- One IGES file
- One picture (max 5Mb)
diameter 8 mm

2. Export Milling file, STL or IGES-format,
for the small Roland milling machine
- Use a SIMPLE 3D-model. With
maxium size 110x80 Height
- Use the SRP-player to make the
- One STL file or
IGES. Yes STL-format is alright! :)
STL is usually only for Rapid Prototyping but the Roland
milling machine like STL :)
- One picture. A screen dump from the
Roland software SRP-player (max 5Mb).
The milling paths should be visiable!
3. Scan an object
- Combine the scanned object with something you
- Scale it to fit in a Rapid
- Leakage free! Fill all holes
- Non fragile! You can not make infinitialy thin
objects ;) A knife must have a rounded edge..
- Smooth! To few polygons make it rough. Export
with more polygons (heavier mesh).
- Non silly file size! 1-10mb is usually
enough. Above 30 mb is overkill.
- One STL file
- One picture from NetFabb
basic showing an error free model.
Save a picture and
a 3D-model file for each assignment.
