The course covers the following items:

• Advanced solid modelling operations
• Modelling of details with freeform surfaces
• Modelling of sheet metal products
• Modelling of complex assemblies
• Varied and unconventional working methods in CAD

After passing the course, the student should be able to:

• create CAD models of good quality of a structured way by utilising the full functionality of a modern CAD system. This includes:

            o   components with complex shapes
            o   sheet metal products
            o   complex assemblies

• interpret complex 2D drawings and use them as a basis to create 3D models in CAD
• analyse and discuss the development of one´s own CAD expertise during the course

During first part of the course (P2), there are two classes of 3h every week. During these classes students are given gradually more advanced exercises, where a 3D model should be created from given 2D drawings. Exercises are done individually, or in pairs. For each exercise the students are allowed a certain time to work with the exercise, ranging from one hour for the first exercise to several 3h classes for the last one. When this time has elapsed, we demonstrate our solution to the exercise, and explain our approach in detail.

At the end of the first period (P2) of the course, students submit an individual, written summary of all exercises, including one or more descriptions of and images of steps of particular interest, an image of the final result, and a reflection of the key learning experiences from creating the model.

During the second part of the course (P3), there is only one class of three hours every week. During this period and these classes students work (still individually or in pairs) with a number of highly complex modelling tasks, selected from a provided set of 2D drawings, classified as either yellow or red. In addition to this, students will carry out a sheet metal modelling task.

At the end of this second period (P3), students individually submit a new report, summarising all activities and key learning experiences during the whole course. This final report should include the (possibly revised) report from P2, but also a summary of and learning experiences from the models created during P3.

Basic proficiency in using 3D CAD, corresponding to the intended learning outcomes for the course MG1028/and for the Introductory CAD module of the courses MF1061/MF1001/MG2128, i.e. you should be able to:

• create a CAD model in Solid Edge or any similar CAD system as:
  - a parameterized part model
  - an assembly of part models
  - an animated mechanism model
  - a fully dimensioned detail drawing of a part
  - an assembly drawing with an exploded view and a parts list

We recommend that you download and install the current version of Solid Edge (Solid Edge 2024) on your private windows computer before the start of the course, see Software below. This enables you to work on your own between classes. If you have not worked actively with CAD for a while, you should also consider brushing up your CAD skills before the start of the course.

The course material consists of the drawings provided and task decriptions, all accessible through Canvas for registered students. We will also upload our solutions/CAD models for the exercises to Canvas, however with a delay, to give everybody a chance to complete the exercise before seeing our solution.

We use Solid Edge in current version (Solid Edge 2024), which can be downloaded from KTH Software Download site, and installed on the student´s private Windows computer. Solid Edge is also available in our own computer labs and in all Windows computer labs on KTH Campus.

Students at KTH with a permanent disability can get support during studies from Funka:

Funka - compensatory support for students with disabilities

A, B, C, D, E, FX, F

• INL1 - Homework assignment, 3.0 credits, Grading scale: A, B, C, D, E, FX, F
• LAB1 - Laboratory exercises, 3.0 credits, Grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Laboratory Exercises ( LAB1 )

Completion and approved written documentation of all compulsory exercises during P2.

Homework Assignment ( INL1 )

Written documentation/final report submitted and approved, and final presentation and discussion completed, all according to the grading criteria published below.

LAB1

All the exercises of the first period (Anchor block; Feed bracket; Coupler; Loco regulator body; Injection pump bracket; Camping Table; Surface modelling exercises #1 & #2/Gearbox side cover, for those who have already done the surface modelling exercises; Front spring bracket; Sheet metal modelling exercise), should be documented in a short written report (typically 5-10 pages), including your approach and a reflection on what you experienced and learnt for each of the exercises. We do not want a complete description of the modelling process for all the models, but you should describe the highlights and the most interesting aspects of each model, in text and figures. All compulsory exercises have to be completed and the report on these has to be submitted to an assignment in Canvas, no later than by the end of P2 (January 13, 2025). 

We will comment on your report and suggest improvements. If we judge your report to be good enough, you will get the first 3 credits of this course reported in Ladok, with a P(ass) grade. If it is judged to be of insufficient quality, we will ask for a revised version before you get the grade reported. The grading of this report will not influence your final grade in the course, but the comments made to your report will help you in improving the quality of your final report.

INL1 & Final grade

For all grades

• document your work (i.e. all exercises and assignments you have carried out throughout the course), in a written report (including the revised version of the report on the exercises of the first period) and upload it to the Final Report assignment in Canvas.
• perform a self-critical reflection on the whole work you have done during the course and the results you achieved, and present these reflections in writing in the final report.
• book a one-hour time slot for a final presentation and discussion of your report, during which you present it together with your created models in an individual grading discussion with Lasse or Per.

For a passing grade (E or D, depending on our judgement of the quality of your
models and report), you should:

• create part models of at least two different drawings, where at least one should be of red difficulty level.
• create a mailbox CAD model of your own design, utilising the sheet metal modelling functionality of Solid Edge, see separate document distributed during period 3/spring semester.

For a higher grade (D, C, B or A, depending on the drawings you have modelled and
our judgement of the quality of models and report). In addition to the above,you should
complete the following tasks:

• from the drawing and the corresponding part model made by fellow student, make an analysis of that student's modelling work (on a yellow or red level drawing), write comments about the quality of the model and if possible and necessary suggest improvements of the modelling process and the
• collect points by creating additional part models from drawings according to the following:

Models of red drawings give 2 points; models of yellow drawings give 1 point.
N.B. The two compulsory models do not count in the collection of points for higher
grades.

• • For grade D/C – Collect 3 additional points by creating part models from at least two
    additional drawings, where the models are of different type, i.e. yellow and red respectively
  • For grade C/B – Collect 5 additional points by creating part models from the drawings where at least one is of category red
  • For grade B/A – Collect 8 additional points by creating part models from the drawings where at least two are of category red

Drawing categories: (green drawings are used for individual training only)
Yellow – complex modelling, complex forms, surface modelling - help is necessary.
Red – very complex modelling, a lot of dimensions, complex forms, no guarantee that everything can be modelled according to the drawing - expert help is required.

Deadlines. For students aiming at a higher grade, the final report should be submitted at latest on April 1, 2025, and the final presentation and discussion should be completed by the end of April 2025, in order to get a higher grade as specified above. A second deadline for submitting the final report, where final grades are lowered by one step, is May 1, 2025, with a final presentation and discussion to be held during May 2025. Thereafter, only the lowest grades, D or E, will be awarded.

Students who get an FX grade on LAB1 after submitting a report, may upload a revised version of the report to get a P grade, however only two revisions are allowed.

It is not possible to raise a passing grade in the course.

Grades for LAB1 will be reported in Ladok shortly after the deadline for the P2 report.

Grades for INL1 and final grades will be reported as soon as possible after completion of all compulsory tasks in the course.

Preliminary grades will also be visible under Grades in Canvas.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.

Replaces the course MG2022 from autumn semester 2023. Only one of the courses can be taken.
