Study Notes
AutoCAD Basics
- Launch AutoCAD software
- Select the right template needed for the drawing, especially based on the units of the dimensions
- In the model view, type Z in the command line and select all
- Create layers using the layer manager
- Define the default layer
- Combine both draw and modify tools to create the drawing
- Create a dimension style and use that to place dimensions on the drawing
Creating a New Drawing
- Click on the Start Page and click on NEW
- The Select box Template dialog box will pop up (fig. 13)
- Select the acadiso.dwt from the list of Templates
- A new drawing workspace will open
- Set the boundary using the Rectangle Tool
- Set the Viewport by typing MV or MVIEW in the command palette and press ENTER
- Activate a viewport by double-clicking inside the viewport
Setting Up the Page
- Set the layers (Line types)
- Set the Text Styles
- Set the Dimension, leader, and Table styles if necessary
- Go to File and Save as template by clicking on SAVE AS
- Select dwt template as your file type
- Click on Page Setup Manager (Fig. 14)
- Add the name of the Template and save the file to a suitable location
Engineering Drawing
- Cylindrical compression springs: coils are drawn only at each end of the spring and are connected by parallel thin lines
- Spur gears: the front view consists of the outside thick circle and the pitch center-line circle
- Bearings: conventional representation does not imply any particular type of bearing
Conventional Representation of Common Features
- Thread (Internal and external)
- Splined shaft
- Knurl
- Shaft
- Serrated shaft
- Holes on circular pitch
- Bearing
Exercises
- Produce the Front, left, and Right End View of the images
Sectional Views
- Introduction to sectional views
- Full Sections
- Placement of Section view
- Labeling Cutting planes
- Half Sections
- Broken out sections
- Revolved sections
- Removed sections
- Offset sections
- Ribs in section
- Aligned sections
- Partial sections
- Parts not sectioned
Assembly Drawings
- Definition: a drawing showing how all of the parts fit together
- Types of assembly drawings: Layout, General assembly, Working-drawing, Erection assembly, Subassembly, Pictorial assembly
- Assembly drawings can contain: one or more views, auxiliary views, sections, enlarged views, parts list or bill of materials
Development of Solids/Surfaces
- Surface terminology: plane, ruled surface, single-curved surface, double-curved surface, warped surface
- Examples of ruled surfaces: plane, cylinder, cone
- Examples of warped surfaces: Figure 57
