CAID2 Advanced level step 2

This 3-point course is in the first year of Master and is a part of "Advanced Computer Aided Modeling and Visualization". (The other part is CAD)

The CAID program used is Autodesk Alias Automotive on Windows based workstations.

Goal and contents

Students are given training in CAID on a deeper level in order to be able to create advanced 3D models and make effective visualizations.

The aim is to give a more in depth knowledge of the tools in a CAID program.

Concepts covered:

Understand the different modeling strategies available to maximize modeling efficiency.
Determine the softwares role in the design workflow.
Customize construction tolerances and linear units.
Construct efficient curves with optimal parameterization and minimal geometry
Define G0, G1, and G2 continuity and the importance of each to curve and surface construction
Manipulate curves using the tools found in the curve edit palette
Understand the criteria for primary and transitional surfaces
Construct primary surfaces using the set planar, revolve, skin, extrude and monorail surfacing tools

Construct transitional surfaces using birail, square, fillet and round
Understand when and where the options related to continuity and rebuilding of surfaces should be applied
Edit surfaces using freeform CV pulling and precise manipulation methodsEvaluate curves and surfaces to ensure desired curvature and continuity characteristics.  Create stitched models for Boolean operations or output to solid modeling packages

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 etc.), tips and traps will be provided
Prepare models for successful rapid prototyping output

 

Prerequisites

Completion of CAID 1

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 school.

In order to obtain credit for the 3-points 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.

Exercises to be completed

1. Modeling and rendering quickly a Flashlight

2. Export Milling files (step or iges) and pictures showing the objects position in space. Use your flashlight or own 3D-model.

 

3. Modeling and rendering a Vacuum cleaner

4. Export a Rapid Prototyping (stl)  file(s). Renderings and pictures from NetFabb basic (free) showing it is a "leakage free" model. Real life scanned data has to be used and combined in some way. Photo, laser or IPad-scanner can be used.
