First of all what is unit, units are a measurement system, in which we have two basic units, Empirical unit and Metric unit.
Empirical unit is old British unit system which is used in US now a days, which includes yards, feets, inches. While Metric is Standard unit system which uses kilometres, metres, centimetres, millimetres for measurements.
To set unit we can write 'unit' in our command section and then press enter, one dialogue box of drawing units will appear, we are given settings for Length and Angle.
In length we have different types such as, Fractional, Engineering, Decimal, Architectural, and Scientific. We will select Decimal as we want to work in centimetres and metres.
Below we can select which unit should be inserted for our content, we will select 'millimetres' and set it's precision from it's column as '0.0'.
We can select the standard of our unit also, we will select 'International'.
We are also given different types of angle, such as Decimal degrees, Deg/Min/Sec, Grads, Radians, Surveyor's Units. We will use Decimal degrees and set it's precision.
After setting all the unit options we can click 'Okay' and continue.
By these following steps we can set units in AutoCAD.
This tutorial will teach you how to change the units in AutoCAD. It is very easy and can be done in a few steps:
Open the “Options” window by going to “File” and then “Options”.
Go to the “Units” tab at the top of the window.
Change your desired units from inches (in) or millimeters (mm).
Click on “OK” and you are done!
The best way to set your drawing units is to set it to a unit that you are most comfortable with. The only thing that may be a problem is if you are working with someone who is using a different unit, then it may be hard for you to communicate your ideas.
The drawing units are the way you measure your drawing. They are usually set in millimeters, inches, picas, points, or pixels. Setting your drawing units is important because it determines how large or small your drawings will be when you print them.
The dimension units of a model in AutoCAD can be changed by using the Dimension Style Manager.
The Dimension Style Manager is a palette that is used to change the dimension units of a model in AutoCAD. It is located on the right side of the screen and can be accessed by clicking on it.
This palette has two tabs, one for setting up new styles and one for editing existing ones. The existing tab has four options:
New Style: This option will allow you to create a new style
Edit Style: This option will allow you to edit an existing style
Delete Style: This option will allow you to delete an existing style
Apply To Selection: This option will apply the edited or created style to all selected objects
This section will teach you how to make sure your dimensions are accurate. The first step is to determine the length of the object that you are measuring in millimeters or inches. Next, you need to measure the thickness in millimeters or inches. Finally, measure the depth of the object in millimeters or inches.
If your measurements are not accurate enough, you can use a ruler to measure and mark off each dimension on your object. Then use a protractor to find out how much is left over when calculating the dimensions of an object, or if it is too wide or too narrow for its depth and thickness.
A linear dimension is a measure of length that is used to measure the distance between two points. It is also known as a straight line. A radial dimension, on the other hand, is a measure of distance that is used to measure the distance from the center point of an object.
The difference between these two dimensions can be seen in this diagram:
In this diagram, you can see that the blue line represents a linear dimension while the green circle represents a radial dimension. The green circle has a radius of 10 centimeters while the blue line has a length of 20 centimeters.
very nice app for learning autocad
Gaurav Bhagwan Thombare
All concepts were explained very well.
Examples for each end every command are given nicely.
Projects includes most of the command present in Auto Cad , that is good.
I love this course.

3D modeling practical illustrations should be more. I have square dome shape plastic molded part and i cannot make its 3d drawing even after watching all the videos.
very good knowledge and content, must Try once
Without any pay you can learn autocad eassily and get job as a autocad engineer. This course is very good.
I've completed my course and quiz but the quiz is not submitting, the whole course started from beginning..... When do I get my final scores and certificate?
Excellent Kash mujhe phele pta hota iss website ke baare me
