Welcome to the forum.
Anything is easy, once you know how to do it.

Start here ..............

2. no.
The professor give me one week more to do this homework.
can you guys help me.

3. I'm having trouble understanding just what you hope to accomplish if you do not even understand the basics of AutoCAD. It seems, from your answers, you were either taught very little, or you did not pay much attention in class.

4. Exercise 1.1 Baseplate.

Make sure you have ORTHOMODE enabled. Use your F8 key to toggle it.

Prior to starting this exercise make a quick hand sketch of the baseplate and put the dimensions on it. You'll notice that you will have to calculate a couple of the dimensions based upon those that are already given. When you have all the dimensions of every side then you can draw the baseplate in AutoCAD.

Note: We will be working our way around the baseplate in a clockwise manner.

5. EXERCISE 1.1.PNG
The order in which the lines should be drawn using the method I described previously. AutoCAD continues to prompt the user to "specify the next point" until the command is cancelled or the last response is "Close".

Here is the sequence that is followed as taken from the AutoCAD Text window:

Command: <Ortho on>

Command: LINE Specify first point:
Specify next point or [Undo]: 2.0 line 1

Specify next point or [Undo]: 2.0 line 2

Specify next point or [Close/Undo]: 2.0 line 3

Specify next point or [Close/Undo]: 2.5 line 4

Specify next point or [Close/Undo]: 3.0 line 5

Specify next point or [Close/Undo]: .5 line 6

Specify next point or [Close/Undo]: 2.5 line 7

Specify next point or [Close/Undo]: 2.5 line 8

Specify next point or [Close/Undo]: 1.5 line 9

Specify next point or [Close/Undo]: c line 10 drawn by AutoCAD automatically

6. EXERCISE 1.2.PNG
I have determined that Exercise 1.2 can be done in the same manner as 1.1 was. When you get to the end of line number 7 just type "C" for "Close" and AutoCAD will draw line number 8 for you. See below.

Command: <Ortho on>

Command: LINE

Specify first point:

Specify next point or [Undo]: .5 line 1

Specify next point or [Undo]: .7 line 2

Specify next point or [Close/Undo]: 1.6 line 3

Specify next point or [Close/Undo]: .7 line 4

Specify next point or [Close/Undo]: .9 line 5

Specify next point or [Close/Undo]: .6 line 6

Specify next point or [Close/Undo]: 1.2 line 7

Specify next point or [Close/Undo]: C "C" for Close

You should now have two exercises done.

7. Where in the United States are you located?

I would recommend that you skip Exercise 1.3 for the moment and move on to Exercise 1.4. You can go back to 1.3 later.

8. Explanation of AutoCAD Function Keys (F1 through F11) at the top of your keyboard.
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

F1 - Opens the AutoCAD HELP file

F2 - Opens the AutoCAD TEXT window in the drawing area

F3 - Turns running snaps (OSnaps) on and off

F4 - Turns 3D OSNAP on and off

F5 - Cycles through the Isoplane Top, Isoplane Right and Isoplane Left crosshairs positions (isometric drawings)

F6 - Allow/disallow Dynamic UCS

F7 - Turns the GRID on and off

F8 - Turns ORTHO mode on and off

F9 - Turns SNAP on and off

F10 - Turns POLAR TRACKING on and off

F11 - Turns OBJECT SNAP TRACKING on and off

F12 - Dynamic Input

From left to right they are...

Infer Constraints

Snap Mode (F9)

Grid Display (F7)

Ortho Mode (F8 )

Polar Tracking (F10)

Object Snap (F3)

3D Object Snap (F4)

Object Snap Tracking (F11)

Allow/Disallow Dynamic UCS (F6)

Dynamic Input (F12)

Show/Hide Lineweight

Show/Hide Transparency

Quick Properties

Selection Cycling

In the far left hand corner is where your coordinates are displayed.

Note the tabs above the Command line. There is always one for MODEL space and two (the default) for paper space LAYOUTS. We draw our objects in model space at FULL size. We do not scale objects in model space like we would if we were drawing them on a drafting board. No matter how big or small the item is draw it FULL size.

Layer Property Manager.jpg
The Layer Properties Manager. This is where you create all your layers and define their properties. The default AutoCAD template, acad.dwt, opens when you start a new drawing. There is only one defined layer (Layer "0" - color: white) in this template. You can create a custom template file with all your layers predefined. It is a real time saver.
