Hi Michael,
Regarding the possibility to easily access curves' control points, i've found a solution that has always been in front of me!
I've written a modified version of Max's DelCorners script, that simply given a bunch of selected curves as input,
creates a bunch of new point objects, automatically selected, representing the selected curves' control points.
I'm aware that this is a simple solution that doesn't allow me to access to the control points' data,
as said by you in your post (

Here's my code :
code:
// ExtractCurvesControlPoints.js v.0.1 - Marco Di Mario (mkdm), 2016
// based on :
// Max Smirnov's DelCorners, v.1.0.2015.09.09
// Given a bunch of selected curves as input, creates a bunch of new point objects, automatically selected,
// representing the selected curves' control points.
function extractCurvesControlPoints() {
var gd = moi.geometryDatabase;
var obj = gd.getObjects(); // get all the objs
var selCurves = gd.getSelectedObjects().getCurves(); // get all the selected curves
if (selCurves.length == 0) {
moi.UI.alert("At least one curve must be selected!");
return;
}
// 1 - deselect everything and turn off all control points
obj.setProperty('selected', 0);
obj.setProperty('showPoints', 0);
// 2 - turn on control points on selected curves
selCurves.setProperty('showPoints', 1);
// 3 - select all the objs
gd.selectAll();
// 4 - doing so, only all control points remains selected.
// In this case, the control points of the selected curves
obj.setProperty('selected', 0);
// 5 - doing so only the control points will be copied and then pasted.
// Pasted objects are automatically selected
gd.copyToClipboardCommand( selCurves );
gd.pasteFromClipboard();
// 6 - turn off control points on selected curves
selCurves.setProperty('showPoints', 0);
// As final result, we have now a bunch of new point objects, automatically selected,
// representing the selected curves' control points!
}
extractCurvesControlPoints();
The ExtractCurvesControlPoints.zip file contains a 3dm example file that can be useful to test the script.
The ExtractCurvesControlPoints.js file can be equally copied to "commands" or "scripts" folder.
I've written this script also for using it together with some NodeEditor's nodes that i'm writing
and that i hope to post as soon as possible.
For example one of these, called "ArrayRemDupl", can be used to remove duplicated points.
That is, given a PointArray and a distance, this node returns a new PointArray, containing only
all the original points, far from each other at least the given distance.
Anyway....thank you for all and have a nice day!
Ciao.
Marco (mdkm).
