Hi there, as the title of the discussion sugests im here to try and get some help on how to create a dashed line that goes from a big thickness to a small one, ive tryed asking on discord chat's no luck, teachers dont reply ... and i cant stay stuck on Creative CV that im making just cuz i want to know if it is possible or not to create what im trying to create.
Anyhow ... this is my life line ... so i hope i can get some help or definite reply that this cant be done.
Im going to give examples of what im trying to acomplish so it can be simpler ti you guys and girls 
Example:
As u can see i can do normal dashed lines fine, but i wated to give an effect on the title below, with a horizontal dashed line that went as the red letter on the image say, and thats my problem i just cant figure out how to change the thickness of the dashed lines to give that effect.
Can some one help me please ??
Regards ASilva
PS: if there is already a place where this was already replyed ... please let me know cuz i didnt find it.

No need to close it, you found a way that works. Other people might find this discussion useful.
I might have created a dashed line set to the widest desired size, then masked it which is really easy to do and is all editable later.

One rather tedious option would be to use a grid script that I created that can set guides at a progressive distance then draw rectangles between those guides. Then move one of the end shapes and distribute the shapes to create spaces.
You could stroke a path with a square Brush, with Roundness set to Fade in Shape Dynamics:
You can try this script. you need to set the sizes you want, and a starting selection for the height of the dashed lines and how long you want it. It would be best to do this on a separate layer then transform your results to fit.
var oldPref = app.preferences.rulerUnits;//stores old measurement preferences so that they can be reset when the script is done.
app.preferences.rulerUnits = Units.PIXELS;
var startingSize = 70//set starting size of dash
var minSize = 2//set minimum size of dash, just so they don't get too small
var dimStep = .95//set how much the dash decreases in size with each step
var dashSpace = 10//set space between dashes
var selArray = new Array();
var doc = activeDocument;
var selBounds = doc.selection.bounds;
var top = selBounds[1];
var bottom = selBounds[3];
var selW = doc.selection.bounds[2]-doc.selection.bounds[0];
var selH = doc.selection.bounds[3]-doc.selection.bounds[1];
var startD = doc.selection.bounds[0];
var endD = startD+startingSize;
var dashSize = startingSize
while (endD< selBounds[2] && dashSize> 1){
//for(var i=0;i<3;i++){
selArray = new Array([startD,top],[endD,top],[endD,bottom],[startD,bottom]);
doc.selection.select(selArray);
fillForeground ();
startD = endD + dashSpace;
dashSize *=dimStep
endD = startD + dashSize
}
selArray = new Array([selBounds[0],top],[selBounds[2],top],[selBounds[2],bottom],[selBounds[0],bottom]);
doc.selection.select(selArray);
app.preferences.rulerUnits = oldPref;
function fillForeground(){
var idFl = charIDToTypeID( "Fl " );
var desc2 = new ActionDescriptor();
var idUsng = charIDToTypeID( "Usng" );
var idFlCn = charIDToTypeID( "FlCn" );
var idFrgC = charIDToTypeID( "FrgC" );
desc2.putEnumerated( idUsng, idFlCn, idFrgC );
var idOpct = charIDToTypeID( "Opct" );
var idPrc = charIDToTypeID( "#Prc" );
desc2.putUnitDouble( idOpct, idPrc, 100.000000 );
var idMd = charIDToTypeID( "Md " );
var idBlnM = charIDToTypeID( "BlnM" );
var idNrml = charIDToTypeID( "Nrml" );
desc2.putEnumerated( idMd, idBlnM, idNrml );
executeAction( idFl, desc2, DialogModes.NO );
}
Assumed, the thickness of the line varies continuously from large to small
(opposed to a stepwise variation), I would use a Postscript programm, like this:
Save as textfile *.eps and load by Photoshop in mode RGB, e.g. with 144ppi, with anti aliasing.
Note: the original text is not garbled.

Hi ASilva:
Do you have a full CC subscription, or the Photography subscription?
I'm asking because this is very straightforward in Illustrator, even for a brand new user using the Width tool and defining dashes. Photoshop is great at photo editing (along with many other tasks), but you are using it for layout, which is better suited to InDesign or Illustrator.
~Barb
Adding to what Barb says, if you draw the stroke in Illustrator and use the Width tool and dashes, you can copy and paste it to Photoshop as a Shape Layer. You can play with the Illustrator settings until you get the look you want.

Also i want to thank people for trying to help but this is turning to not what i want i tried doing some of the exmples, not counting the code ones cuz i dont know how and where the code works on PS. Also Illustrator didnt try that ither cuz i dont have that 
Any how ... i kinda opted to go a diferent route on my desing and just use 3 simple lines that im going to show u
Once again i say thank for the people that tryind to help ... but i opted to go with this.
Regards ASilva
PS: How does one close the discusion ?
WoW that was exactly the effect i wanted to give i just wasn't able to get, that made me go another route ... i think im going to try and replicate that on my project and see how it looks cuz from ur Tutorial it look awesome ... it was so simple im amazed by the fact i didnt reminded to create it like that ... im so noob sometimes.
Anyways thanks a lot once again
Might be a bit late but this seems very easy to do. Consider these stroke settings.
