How can I get the value or force the distance between two points using the add sop to be uniform; is there an expression ?
As I want to set almost precise measurements.
Distance between (add) points ?

@matthias_k - Your vex example generates the connected lines by a re-sample based on how many points are added along the normals, and it's a great approach. Except, I want to attempt it another way whereas in my method the points are connected by the poly tab of the add sop then I uniformly adjust the spacing between each point.
If I create multi-parameters for each point, if I'm understanding you I'd need to control the spacing between each point. Is there not a vanilla expression (non-vex) I can use ? I've attempted channel referencing by referencing a previous points position (py0,py1 etc) then multiplying for example but it's not accurate.

@matthias_k why do you always claim what you did is stupid or dumb ? Or is it just a phrase you like to use when posting and shouldn't be taken literal ? 
I never created and HDA. I assume by adjusting the distance sliders you can adjust the distance between the points. How about one slider adjusting the uniform distance between all points created with the add sop while using the polygon tab of the add sop to connect the points via lines ?
What is the guts of your HDA, if you don't mind showing or explaining ?

Hi Christopher,
the HDA shown above was a simple “try”…
it does not deliver the result wanted by me.
What it is doing now:
It creates a point for each “add”
then it assigns a normal based on the direction inputs
and moves the point based on the distance along the normal.
What it is not doing at the moment:
It does not really computes the new “null position”
based on previous point position.
I'll refine it and post it when it's finshed :-)
Then you can have a look at it and maybe it is doing,
what you need.

matthias_k
here is the none finished version…
Silly question, where are your parameters, as in; “my_points” ?
@matthias_k you presented some great methods for this problem, except I hope we can attempt one more as suggested; I was originally thinking, if there was an expression I could apply to the add sop and it would uniformly separate the points based on one parameter ?
If I didn't explain thoroughly let me know
Don't mix up your solutions

Switch added to have one distance param……
and now using pos from previous point
To come back to your expression:
The “add SOP” is generating points based on world space position.
If I'm right, then you can not get a unform distance between points
with this input option at all without problems.
Because you have to calculate the direction and then move the point
to the new position….
How is the distance defined?
+ you'll need first all points to iterate over them
and why would you like give world position, when you move it to another location then?

I couldn't find any information that relates that the add sop lays points down in world space; how did you know ?
When you create a multi-parameter there not available for the user change, when hashtag is added ? There simply for, well, place holder in the code
Interesting concept of using the cosine & sine to position the position of the points.

in world space;
you're right “world space” is the wrong “word”
what I like to say was, the points do not inherit positions from previous point.
When you create a multi-parameter there not available for the user change, when hashtag is added??? It is on the “add_moves” subnet
Is the scene helpy?

The scene is helpful
There is no method to which to uniformly separate point by inherit the position of the previous point created by the add sop, neither regular expression etc. Looping over all the points and storing the results in a parameter is the only solution, from what I understand.
I assume I don't need to create an HDA and could create whether vex or attribute vop and place the parameters on each of either node ?
