CAD systems - Division of Geometry

Course ID: 2-MPG-150/15

Continuous assessment: Individual work on assignments

Learning outcomes: After completing the course, students will be able to work with CAD systems: QCAD/LibreCAD, SketchUp, SweetHome 3D and FreeCAD at the intermediate level.

Course syllabus:

Drawing basic shapes in QCAD (line segments, rectangles, arcs and polygons).
Dimensioning, hatching, creating blocks and manipulation with blocks, working with layers.
More advanced QCAD functions – trimming, arcs and lines connecting, working with text, adjusting dimensioning marks, etc.
Basics of work in SketchUp. Layout description, environment adjusting (toolbar, layout). Usage of push and move tools. Creating simple objects.
Usage of advanced SketchUp tools.
Overview of interesting SketchUp plugins.
Basics of work in Sweet Home 3D (creating walls, rooms, adding and placing furniture; adjustment of colours and sizes).
Sweet Home extensions, adjustment of texts, creating skew walls, work with lights, adjusting colours, importing own models and new objects.
Basics of work in FreeCAD. Layout description, creating simple objects.

Course evaluation:

To obtain grade A to E you have to work on individual projects (each takes about 1/2 to 1 hour of work). Each project must be submitted within two weeks and presented at the end of lecture. The project can be submitted by email only once, if a disease or other event makes it impossible for you to come to the lecture. If you do not present some project, you lose 1 point. If you submit an assignment after deadline (after two weeks from task entry), or your project is unsatisfactory, you lose 1/2 of point. Tasks are entered after each lecture, the last one is entered two weeks before the end of the semester. Tasks submitted after the end of the semester will not be considered. The resulting grade is calculated by subtracting the points you have lost from grade A. If you lose more than 4 points, your resulting grade will be Fx.

Literature:

FreeCAD.sk - an overview of free Free CAx systems, CAx add-ons and CAx resources for different professions.

Assignments:

In QCAD, draw a simple house with a chimney and a window, fence (or a dog house), tree with apples, sun, mountains and clouds. Optionally draw smoke to the chimney or rain to the cloud (use layers, colors, different thickness, various hatches and line types). An example of the result is here.
In QCAD, draw your name and surname with "bold" letters (use trim tool and offset tool, then use layers, colors, hatches, blocks). Draw dimension marks of the first letters of your name and surname. An example of the result is here.
Using QCAD, draw the frontview, topview and sideview of a kitchen stove (use colors, hatches and blocks, draw the most important dimensions). An example of the result is here.
Using QCAD, draw the frontview, topview, sideview and isometric view of this component (use the isometric grid, if it is convenient for you).
Use SketchUp to create a simple model of a house with a sloping roof, chimney and fence. All elements must have a thickness, including walls and fence. An example of the result is here.
Create a "nice" chair and table in SketchUp, and then use these objects to create a kitchenette in the house model from the previous work.
Create a new house or modify the previous house's model so that it has two floors. On the first floor, create a kitchen, living room, toilet and bathroom, at the second floor create at least a bedroom and a children's room. The model of the house must have real dimensions (use dimensioning to verify actual dimensions). Use at least 4 plug-ins for creating windows, roof, doors, stairs and shelves in your model. At least two rooms must be fitted by furniture (use your own model of table and chairs from the previous work). Use layers for furniture in rooms. You can download other objects from the Internet. Please add some trees and the bench in the exterior.
Your house could look like this: view on the ground floor, view on the attic, overall view on the house.
Create 7 view scenes for your house model. The first four views will be: Left View, Right View, Top View of the first and second floor. Hide the exterior layers in both top views. The last three views of the house will be from three different directions, with hidden layers for the interior (furniture, etc.) but with visible layers for the exterior. Use appropriately adjusted cutting plane in the one overall view. You can be inspired by this video.
As an alternative, you can create a virtual tour of your house. An example of a video is here.
Use the Match Photo technique to create a model of a building in SketchUp. You can use, for example, this template.
Use Sweet Home 3D to create a small apartment with furniture. Create rendered images of two rooms.
In Sweet Home 3D create a completely furnished apartment. Use the table and chairs created in Sketchup. Next, import at least 3 pieces of furniture from Google Warehouse, place your lights in the room and create one rendered image of one room and one video.
