Reflection Questions:
1. Size dimensioning shows how large a specific line or distance is, while location dimensioning shows where a point is.
2. Chain dimensioning shows the dimensions of adjacent parts in a series. Datum dimensioning shows sizes in relation to a specific point or line. This is more accurate than chain dimensioning.
3. Using a dimensioned drawing makes it absolutely clear how an object is physically constructed. It is easier to visualize or use than a written description. Also, since dimensioned drawings follow a set of standards, they can be understood by everyone.
It is very clear and easy to see. I believe for your CAD drawings you were supposed to make all of the sheets size A, it makes everything a bit easier to see. Or if possible you could make your images bigger but I'm not sure how the blogger editor restraints will work with you for that.
