I use a little freeware program called LICECAP.  A Search will give you several places you can download it from, such as Cockos Incorporated | LICEcap.

Hi Mr. Cooper, may I know what software you're using to capture the sreenshot animation like your post (3rd post of page 3)?

I had previously posted a discussion about that with an AutoCAD file but got no answers.
They're in the DXF code 12 and 13 entries in entity data -- see >this<. -- or the StartTangent and EndTangent VLA properties, or in the (getpropertyvalue)/(setpropertyvalue) world, the StartFitTangent and EndFitTangent properties.  You can play with them in the Properties palette, too.

With the POINT command, with Snap turned on so they are all at grid locations.  They are there in the image only to illustrate -- it is not necessary to have them there if you can visually pop to positions in that kind of regular relationship.  In the case of the relationship in my image, the relative position of each location is like a Knight's move in chess, but you'll need to experiment to decide whether that makes a shape enough like what you want.

About tangent of spline, see eventually : 

TEST SPLINE 01 Aa.dwg

in the CAD / BIM Blocks library and / or test the command SPLINE on your computer.

Hi Mr. Joseph. I don't know what "tangent of spline" is.
Can you explain and show me please example by pic or animation?
Thank you.

The "good" thing to do when drawing a spline is adding start and end tangents.
In the old AutoCAD version you could do this after but now I haven't find the way to "catch" those tangents so I add multiple in line points and then trim the spline were it normaly begins and ends.
Any informations about start and end tangents ?

Well, this may not be any more precise about matching the wave shape, and seems like a lot of work compared to other approaches, and hugely more difficult if you need to adjust it.  But I would do it with Snap turned on and a series of regularly-spaced positions.  Here, Snap and Grid are both set to 1 drawing unit -- note how the cursor pops to only grid positions.  I pre-positioned Points [green] just to illustrate what I was up to, but they are not needed.  You will want to experiment with the arrangement for "close enough" precision.  This is in a SPLINE command.
