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
