Description
Material-No.903 Alloy Aluminum
Die No.20IT
Dimensions are in milimeters

Full Section

Drawing of a building that appears as if a viewer is looking completely through it

Half Section

View of a section of an object that is taken halfway through with the other half depicted from the exterior, showing the object with half cut away, showing the inside.

Offset Section

A sectional drawing created by a cutting plane bent at right angles to features as though they were in the same plane

Revolved Section

A sectional view that is revolved 90 degrees and perpendicular with the plane of projection

what is brief design

• a document
• an insurance between parties, may be changing later by the situations.
• a basic description on what is expected. Both parties know approximately what they're entering into and what are they committing into.
• often design brief and project plan are discerned as a same thing

Content of the Brief

-project backgrounds/ types

-directing resources

-results

-General Facts

Why design Brief

-the personnel might change

-avoid waste of time

-starting is easier and faster

-recognize biggest challenges in advance

-not rely on intution and time running on commumication between people

-no suprises with prioritization, exppectations and results in project work

-things might change. its important to know what is existed in the beginning, to understand and reflect the changes

BRIEF IS MEANT TO BE ALIVE

Dimensioning includes measurments, notes and symbols

Placement of Dimensions

Dimensioning Diameters

Dimensioning Radii - which do not need their centers located

Dimensioning Rules
-dimensions should not be duplicated or fiven on a drawing in two different ways.
-dimensions should not be placed in the view where the best shape and true form are shown.
-avoid long extension and leader lines.
-place a dimension between views, especially if it applies to both ciews and will improve clarity
-do not assume that a part is symmetrical. Dimension both sides of a symmetrically shapped part or use the centerline cymbol or not to avoid confusion.
-spacing between dimensions should be consistent within a drawing
-line up dimensions horizontally and vertically where possible.
-avoid crossing dimension lines or leaders where possible.

This week we were introduced to 2 new objects that we had to create.

The plane figure, with dimensions

This week we started to build the bridge

also researched on how to enhance the design

This is the Jig spacer re-done

This week we were introduced to a bridge building contest which we are going to take part in.

Mohawk bridge building contest

This week we made more objects using AutoCAD. we learned how to add dimensions to our objects that we have made. Next week we will be participating in making a bridge using the concept of AutoCAD
