Day 5 of my CAD journey 📐
Learned geometric constructions:
• Circle – all points are equally distant from the center
• Arc – a portion of a circle
• Polygon – a closed shape made of straight sides
These are the building blocks of engineering drawings.
Day 4 of my CAD journey 📐
Learned about lettering and drawing layout.
• Lettering makes drawings clear and readable.
• Drawing layout includes the border, title block, drawing area and dimensions.
• A well-organized drawing helps others understand the design easily.
Day 3 of my CAD journey 📐
Learned about scales and measurements.
• Scale = ratio between drawing size and actual size
• Common scales: 1:1, 1:2, 2:1
• Engineers mostly use metric units like mm, cm and m
Today I learned about engineering drawing lines:
• Visible lines
• Hidden lines
• Center lines
• Dimension lines
Each lines has a specific meaning in engineering drawings
Day 2 of my CAD and Engineering Drawing journey.
Today I learned about engineering drawing lines:
• Visible lines
• Hidden lines
• Center lines
• Dimension lines
I also learnt drawing equipment and standards
1. Traditional drawing equipments: before CAD engineers use e.g eraser, pencil, compass protractor, set square e.t.c
2. Drawing standards.
Day 1 of my CAD and Engineering Drawing journey.
Today I learned:
• What CAD (Computer-Aided Design) means
• Types of engineering drawings
• Basic drawing equipment and standards
There are different types of engineering drawings:
1. Orthographic Drawing
Shows an object from different views
2. Isometric drawings
3. Assembly drawings
4. Details drawings
5. Sectional drawings
