1. Geometric Courses for Architectural and Teacher Students at the TU Graz O. Röschel Zagreb, February 2007

2. Geometric Courses for Architectural and Teacher Students at the TU Graz Contents: Geometric courses under new technologies (integration of CAD) I. Courses for Architects in the 1st and 2nd semester II. Courses for Teachers and the Architects in the 2nd year Examples of Geometric Topics (including CAD) III. Conclusions Introduction of: Mathematica, Maple and CAD-packages Here: Restriction to the combination of the geometric education with the use of professional CAD-packages! → Look for geometric problems which can be worked out now!

3. Geometric Courses for Architectural and Teacher Students at the TU Graz Introduction of: Mathematica, Maple and CAD-packages Here: Restriction to the combination of the geometric education with the use of professional CAD-packages! In order to enhance the spatial abilities of students: Direct work in a virtual 3D-space (3D Model space) → Look for geometric problems which can be worked out now!

4. Geometric Courses for Architectural and Teacher Students at the TU Graz • I. Courses for Architects in the 1st and 2nd sem. • „Methods of representation“: • 2 lectures in 1st sem. • 2 exercises in 1st sem. • 2 exercises in 2nd sem. • Joint courses of the institute of geometry and the institute of media in architecture • The aim: Balance between descriptive methods and the use of a CAD-package (AutoCAD)

5. I. Courses for Architectural Students • „Methods of representation“: • (A. Wiltsche, Varaždinske Toplice, 2005) • Winter term:Exercises - 5 homeworks: • 3 drawings by hand: • Axonometry • Perspective • Reconstruction

6. I. Courses for Architectural Students • 2 AutoCAD-works: • Technical drawing (architectural plan) • Solid modelling of a real world‘s object • Summer term: • 6 Homeworks: • Pixel graphics, Rhino3D for surface modelling, animation • Examination at the end of the lecture: Divided into a drawing and an AutoCAD part. • Details….

7. Geometric Courses for Architectural and Teacher Students at the TU Graz • II. Courses for Teachers and Architects (beginning in the 2nd year) • The aim: • Training the experienced use of a professional CAD-package combined with geometric contents • Examples: • „Professional CAD-packages“: 2 proseminary • „3D-constructing with AutoCAD“: 2 hours • Training of teacher students of „Geometry“ (in combination with „Mathematics“)

8. Geometric Courses for Teacher Students and Architects • Professional CAD-packages • MicroStation (or AutoCAD) – proseminary (2 hrs/week) • Combination of teaching and solving of given problems • 5 Units: • Unit 1: (3 weeks) Handling with MicroStation‘s plane features • Unit 2: (3 weeks) 3D-features and solid modelling with volumes • Unit 3: (3 weeks) References and hierarchical block-structures • Unit 4: (3 weeks) Modelling of surface models • Unit 5: (3 weeks) Animations and exchange with other packages (AutoCAD, VRML, …)

9. Professional CAD-packages (for teacher students) Unit 1: Handling with MicroStation‘s plane features Homework 1: 1a. Follow the examples of the lecture and determine a planar band ornament with at least 5-fold rotational symmetry, which contains parts of straight lines and circles. Submit the DGN-Files with the name „Name_arb1a.dwg“ to roeschel@tugraz.at – Subject: „Prof_CAD_Pakete_1“. Deadline: 2.11.2006 A student‘s result:

10. Professional CAD-packages (for teacher students) Unit 2: (3 weeks) 3D-features and solid modelling with volumes Homework 1 (cont.): 1b. Follow the examples of the lecture and determine a volume version of the band ornament from 1a. It shall consist of at least 10 congrent pieces, which stick together without self-intersections.

11. Professional CAD-packages (for teacher students) Homework 1b: A Student‘s work

12. Professional CAD-packages (for teacher students) Unit 2(cont.): 3D-solid modelling with volumes and 2D-output (references) Homework 2: Determine a DGN – File with the following contents: 1) The file shall contain 6 solid models (cube1 to cube6 as modified copies of the default model) with TSCHUPIK-cubes. 2) Use references to generate a layout with axonometric images.

13. Professional CAD-packages (for teacher students) Homework 2: A Student‘s work (Exercise for spatial abilities)

14. Professional CAD-packages (for teacher students) Unit 3: References of spatial objects and star polyhedra Homework 3: Use an hierarchical block structure to implement the action the iscosahedral group. Start with a regular pentagondodecahedron and determine different star polyhedra: The small and the great stellated dodecahedron. Additional: Are you able to generate the other stars of this type, too?

19. Professional CAD-packages (for teacher students) Unit 5: Export and Animation Homework 5: Generate an animation which simulates the „growth“ of regular pentagondodecahedron to a rhombi-triakontahedron (and to the deltoid-hexakontahedron, resp.). Export the animation into a VRML-File. Example: From the cube to the rhombic dodecahedron to the deltoid-iksositetrahedron.
