Can someone please tell me how to do technical drawing of a spring in 2D like below pics?

Hello dery, I supose that you want to do a 2D file of a 3D view like on the 3 pages shown.
If I say that you will have to follow the different steps descibed will it not be OK for you ?
Thoses methods are now a little old and I would do instead a 3D solid to be converted into a 2D view with a FLATSHOT.
Eventually see my file : ORTHO-TO-ISO_01_B.dwg in the CAD/BIM Blocks library and it will show the rules of the isometric view.
Eventually see my file : Spring 3d taller-PJH to see how to generate a 3D solid of a coil spring.

Yes, please teach me technical drawing way by using ellipse template, curve, triangle, and divider (or compass).

[Don't the pages you posted do exactly that?]

Hello dery and Kent, at first I saw this post as a "save me, I'm a student and I don't succeed in doing this homework" so I rearranged the 5 exercises of the 3 pages.

Here is one example rearranged line by line.

Then I realised that the problem would be more geometry knowledge than drawing as I see at the 2nd sentence of the STEP 2 and also because I find that the explanations + drawings are self explanatory, so I don't know what to do to help.

P.S. dery, if you have a plain AutoCAD Mechanical 2014 you can easily elaborate a 3D spring and then eventually do a FLATSHOT to get a 2D view.

Can someone tell me step-by-step how to draw below using ellipse in ACAD? The author says that below is drawn using ellipse template/guide. The drawing (the curve) look smooth, can anybody teach me like that?

Hello dery, as I don't know the ratio OD/Pitch I will "only" give you the ratio valid for an isometric ellipse.
The isometric ellipse will be the upper and lower extremities of your spring.
The rest can be schelmatic I suppose.

Why you only draw an isometric ellipse?

Hello dery, drew "only" the isometric ellipse because the rest will be schematic I think.
With that isometric ellipse you can have easily the upper extremity of the coil spring step 3 and if you choose a certain x pitch you can draw the rest, normally you have already the complete method.
The examples that you show are manual drawings I think and are simplified.
I will take a look at the all 2D process later but at that time I'm no longer producing isometric drawings as I'm more 3D ( + eventually 2D FLATSHOT ) and obviously the result will be a little more realistic than this.

You say that you have AtoCAD 2014 ( plain version I suppose ) so you can perform 3D solids.
As I said earlier eventually see my file : Spring 3d taller-PJH to see how to generate a 3D solid of a coil spring.

What about this? Can you make a 2D spring like below pic using ellipse in AutoCAD?
What about in dimetric, 2-point, and 3-point perspective projection?
