AutoCAD Mechanical Parts - Orthographic Projection

Project Description – ENGR 1201 AutoCAD Project 1

I need a complete AutoCAD 2026 drawing for Project 1 – Orthographic Projection, Layers, Sectioning and Dimensioning.

There are 3 separate mechanical parts:

Engine Chock

Seat Bracket

Generator Mount

Each part must be completed separately.

General Requirements

For EACH part:

• Create correct orthographic projections:

Front View (properly selected)

Top View

Side View

• Create one proper Section View

Show correct Cutting Plane Line

Use correct hatching (steel material)

Do NOT hatch holes

• All holes are THROUGH unless specified otherwise
• For Engine Chock: one hole has depth = 5

Layers (Must Be Exactly As Follows)

Object Line
Continuous – 0.70 mm – White

Hidden Line
Hidden – 0.40 – Blue

Center Line
Center – 0.35 – Green

Dimension Line
Continuous – 0.40 – Red

Construction Line
Continuous – 0.40 – Red

Section Line
Continuous – 0.35 – White

Cutting Plane Line
Phantom – 1.0 – Magenta

All objects must be placed on correct layers.

Dimension Style Requirements

Text Height: 3
Arrowhead Size: 3
Offset from Origin: 1
Precision: 0
Decimal separator: period (.)
Dimensions must be Unidirectional

For circles and arcs:
Use Multi-Leader, NOT AutoCAD radius/diameter tool

Multi-leader landing distance: 3

Layout Requirements

• Each object must be on its own Layout tab
• Proper viewport scale must be used
• Viewports must be locked
• Drawing must be clean and properly centered

Title Block Must Include

Part Name
Part Number (my student number)
File Name

Scale
Date

Deliverables

DWG file (AutoCAD 2026 format)

PDF version of each layout

File name format:
StudentNumber – Project 1

Grading Breakdown (Important)

Orthographic Views – 45 marks
Sectioning – 13 marks
Viewport Scale – 10 marks
Layers – 7 marks
Dimensioning – 25 marks

Accuracy is very important. Missing or incorrect lines lose marks.
