Should it only place a cpoint for overlapping edges (but does not split each other? )
In fact just put a CPoint at any real intersections of a selection of lines and/or circles, arc circle and /or curves
on faces or in the space
(i don't know if it's an hard work or not)

for the existential question
an Arc Circle A has a Cpoint CPA, xa , ya, za
an Arc Circle B has a Cpoint CPB xb, yb, zb

but of course as you can see on my previous image
because arc are from a same circle
xa = xb, ya = yb, za = zb
So my question what about this "double CPoint"?
is there 2 Cpoints or you merge it in only one?

Where edges are split where they intersect? Or where they overlap - like they often do in SU6 and older?

Doesn't check for existing CPoints.

I don't know, on the face I suppose

In any case we have solution to move them out the face (when existing)
call the plug, and re put on the face

So there are 2CPoint overlaped
or they are automatical merged as one by SU as having same coordinates ?
(same than you draw 2 lines ovelapped)

Something is lost in translation here - I mean should there be a CPoint only when two edges cross each other but doesn't split each other?

I don't know - I haven't tested it. The plugin just adds a CPoint blindly.

pilou

I have just tested seems there are really 2 CPoints!
Maybe some annoyous

I think Pilou's issue with 'duplicated Cpoints' - i.e. at the same location in 3D space - is if they are used to place Instances later it will duplicate the Instances etc.
When adding the new Cpoints it'd be relatively easy to test to see if there was a Cpoint already there.
First make a collection of Cpoints in the current context [entities] and make an array of the 'position' of each one: then only add the new Cpoint if it's not already there - code-example...


there=false
cpoint_positions.each{|p|(there=true;break)if p==new_point}
entities.add_cpoint(new_point) if not there

You should still add coincident Cpoints if they are in different contexts [entities-sets]...

thomthom

Slightly trimmed variant:
entities.add_cpoint(new_point) unless cpoint_positions.any?{|pt|pt==new_point}

In fact that must be 6 points!
1 Center of circle
1 Intersection of lines
4 Intersection Lines Circle

Here I have a lot of more
I have made Intersection before launch the plug Edge/edge (V 6)

Edit I have found a Process
General Intersection
Hide Circle
Call the Plug Guides Tool - Edge/edge
Show Circle
Select Circle
Call ad Cpoint to Circle
I have my six points
Easy for not numerous circles but for many ?
Ok I can use Selection Toys Circles

thomthom

Why do you hide and show the circle?

pilou

Yes see my edit text
In fact that must be Selection Toys "Arcs"
Hide
because the interections are made before

Process must be
Ad CP Circle(s)
General Intersection
Selection Toys "Arcs"
Hide
Add CPoint Edge /Edge
Show Hidden

When Edge / Edge Cpoints are they "Doubled" between 2 segments of a same lines or not? (like my lines above after the intersection)
(at the commune extremities)
Seems not! (I have verified with the outliner)

You have just the problem of same arc centers of my previous old post

Dear Thomas,

Could the following be added to the suite of cpoint functions?

To place a construction point at the intersection of three orthogonal planes.

Thanks,
Bob

Should be straightforward...
Get line of the intersection of two of the planes.
get the intersection of the third plane and the line.
Add a cpoint...

@ Thomthom
Does it possible to have an option for DWG export?

Problem is: Tocad don't import CP POINT !!!
So circle center oe arc circle center info are losted!

So a possibility is to replace CPoints by 2 or 3 lines crossed.(3 axis)
(as "component" even Tocad lost the "component" it draw the lines!
And each circle is tranformed in disc by ToCad.

So Replace CPoints by crossed lines will be fine for DWG export

Of course the replacement can be made by Selection Cpoint/Put Component at Cpoints.
(problem of mutiple same CPoints must be also resolved)
