What’s New

I. What does a picture tell?
Look at the two pictures below and answer the questions that follow:

1. What is the difference between the two pictures?
2. How do you feel about the persons in the pictures?

What Is It

Occupational Health and Safety is a planned system of working to
prevent illness and injury where you recognize and identify all the hazards and risks in a
workplace to prevent them from happening. It is the responsibility of all persons who are
working from the top level of authority down to the person at the lowest level of authority.
Computer and technology industries must also be aware not only of the hazards found in
the workplace but also in using the computer. Hazards must be identified where workers
are working and decide how dangerous it can be.

The common hazards encountered in the workplace are the following:

1. Physical Hazard – this refers to an unsafe workplace condition with unsafe is

work practices
2. Chemical Hazard – this refers to solid, liquid, vapor or gaseous substances
3. Biological Hazard – this is caused by organisms as bacteria, fungi and

parasites
4. Mechanical Hazard – this refers to a hazard caused by powered tools/

equipment/ machine or manual use of tools/ equipment /machine.
5. Ergonomic Hazard – this refers to a type of hazard in which the environment

one of the physical factors that may cause musculoskeletal injuries.

What Is It

Some changes to AutoCAD must be done to use it as a drafting tool for
drawings. This type of drafting is commonly practiced in the world. However, making
drawings of a building is quite different from making drawings of an automobile part.
The changes are fairly simple to achieve and it involves two types of set-up and these
are the following:

1. Creating a Template File – this should have required variables set,
including the layers, text styles, dimension styles, layouts and plotting standards
created only for architectural drafting purposes.

2. Creating a User Profile – this will save the looks of the screen that you
want and where AutoCAD will search for files. A personal profile can be loaded when
you start a new AutoCAD session at whatever computer you will be working on.

Template Files

When you begin a drawing using AutoCAD, you will be drawing in an
environment that has pre-set variables set-up by Autodesk for what they consider to
be the most common use. However, some settings that come with the software are
not good for drawings used in the architectural and interior design industry so they
need to be changed by the user to comply with the standard drafting conventions.

Using a Template File
To use a template file to begin a new drawing, follow the steps below:
➢ Click the Menu Browser>Save As...>Drawing Template>
specify the filename, then Save.

Templates have the filename extension of *.dwt.
The most convenient way to make your standard settings permanent if you want
to reuse it later is to create your own Template File. Begin a new drawing, set
the drawing variables as you want them to be set, and then save the drawing
as a "Template" file for reuse on future drawings. This new file will have no
"entities" in it (lines, arcs, or circles), but it will include the following variables:

➢ Your list of LAYERS, with associated line types, colors,
and line weights

➢ Text styles
➢ Dimension styles
➢ AutoCAD variable settings
➢ Layout settings
➢ Viewport(s)
➢ Name of each viewport
➢ Scale of each viewport
➢ Plotting parameters of each viewport, such as what

printer to plot to
➢ Paper size,
➢ Plot scale
➢ Drawing orientation,
➢ Plot style table (pen assignments)
➢ Title sheet information

LAYERS

What I Need to Know

At the end of this lesson, you are expected to:

➢ Recognize how a layer is being used in computer-aided drawing;
➢ Prepare drawings as per building standards; and
➢ Appreciate how computer-aided drawings provides convenience.

What Is It

Layers - key components for organizing AutoCAD drawings. It is a way of
managing, tidying and controlling the visual layout of a drawing. The layers can
include the external walls, internal walls, doors, windows, fittings, text notes,
dimensions, etc.

The separate lines and shapes representing
each part of the house would be arranged on
its relevant layer. Each layer could be assigned
its own color.

Layers are controlled by the layer property manager button, located on the
object properties toolbar.

From the layer property manager, we can:

➢ Add a New Layer – click the ‘New’ button to create a new layer.
click the ‘Delete’ button to delete selected
➢ Delete a Layer – layer
click ‘Current’ button to set the selected layer
➢ Set Current Layer – objects
click the ‘Show Details’ button to see more
➢ Show Details – detailed information
displays the layer name
➢ Name – controls the layer through the lightbulb icon
➢ On – (On or Off)
freezes the layer in all viewpoints
➢ Freeze in all VP – locks a layer, prevents any content from
➢ Lock – being altered
change this to whichever color you desire
➢ Color – examples of this are continuous, dashed and
➢ Linetype – dotted
the thickness a line that appears
➢ Lineweight – select this if the layer is to be plotted or
➢ Plot – printed

If a new AutoCAD drawing is created, everything appears on the one default
layer, named 0. In creating drawings, the layer 0 should not be properly used and
new layers must be set up with names corresponding to the content.

The color and the line style of entities drawn with AutoCAD should be
determined by the layer on which those objects reside. However, it can be overridden
by specifically defining the attributes for the object in the drawing. This can be done
using the color and linetype commands. The color of an entity is used to identify the
pen to be used when the drawing is plotted.

What’s More

Let’s Do This:
