At the bottom side you will also see command line bar where you can see the commands you entered. Command is a way of interacting with nanoCAD. Instead of selecting the command on screen from bars, you can write command here. On top section of command line bar, you will see the history of commands and bottom of bar you see the command you are entering now.

Click “Ctrl+N” or “File>Open” to open a new nanoCAD drawing. You see now your bars are activated to get your commands and you now have a “+” shaped arrow on black side of the screen.

If you still have “inspector” bar on the left opened, you may close it for now, we will get into deep with it later. 

You see that on the left bottom side you have x, y and arrows. This is for axis system. x-y axis system is used throughout the drafting. This is to define how much where you need to draw a line etc. Software actually can’t understand you by words but it actually understands if you say “draw a line with 5mm to the x direction”. 

So, let’s do it.

Write “l”. You see now that the command line is waiting for you to specify the first point.

Here you can write 0,0 to say the program that you want to start to draw a line starting from x=0 and y=0.

Now you can see also that you can see the line is going through your +. You need to enter the next point as the command line asks you. Here you get it that you can also click to specify the second point, or you can write the point as we did here. While selecting freely you can see that on the bottom left side some numbers are changing; 

Here the first number is the length of the line and the second one after “<” is the angle from the axis. 

So, write to command line 5,0. And click “enter” on your keyboard. So, it has finished the drawing line. So, if you can’t see the line don’t worry it is under the axis system arrows. To see it you need to “zoom in”. To zoom in you can use the wheel on your mouse. 

As you zoom in you see the line under x-y axis is coming on screen. This is because as you zoom in the length of the x-y axis symbol does not change but the lines you draw will change. Anyway, you are getting used to with the environment fast. You can now want to see other sides of the screen. What you do with a real piece of paper? You can pan it right? Here at nanoCAD you can easily do it by using wheel button. By clicking on wheel, you see that your pointer on screen changed to hand. 

With this state you have ability to pan the drawing anywhere you want so that you can easily get a better view of your drawing. 

So, these two movements at the nanoCAD, are very much used pan and zoom in/out. You can use them as much as you can so that you can easily see the drawing you draw. 

If you double click the wheel button, nanoCAD automatically centre the drawing you drew. 

At NanoCAD there are more than one way generally. Other easy and fast way to draw a line is to click to the first point and move your pointer to the direction you want to draw the line, 

As you can see it will also show you the direction that it will draw the line. Then you can just enter the length from keyboard, so enter 5 and enter. So, you get the idea.

When does the engineering started? It is a very complex question. Because, people started to construct simple machines before engineering profession is defined. According to that concept we may say ancient times. Because people started to produce simple machines like pulleys, lever and wheels at that time. Some people also started to build tools very long long time ago. These are all before 5000 BC. Except those we may check the written sources to track.
