The bad news are ... well you know them already don't you? he ,he.
The ugly news are that you'll need a LOT of other stuff (most notably clash detection) in order to design a real-life truss. Activate all the 3 available boolean toggles and see what I mean. Clash detection is performed obviously via trigonometry and NOT via Brep to Brep soild "ops".
BTW: Given the opportunity, in general and in order to avoid using excess material I would strongly recommend to work on triangulated meshes (and/or line graphs). The real-life benefits in cost are pretty colossal. Of course by making negative the "d" you can control the triangulation "orientation" (usually the skin is applied there).

N, O}. In this case it's very obvious what needs to happen. You want to create lines combining the following points {AK, BL, CM, DN, EO}.
If the second set however only contains 3 points {K, L, M}, it is no longer obvious. The default behaviour for Components is to keep on matching points until both sets are depleted. This is called Longest List Matching. It will give you 5 lines, that connect the following points: {AK, BL, CM, DM, EM}. As you can see, the last point in the second list (M) has been 'recycled' three times.
You can also change the default data matching behaviour. For example if you change it to Shortest List, then the component will stop working as soon as the smallest set is depleted: {AK, BL, CM}. In this case the points D and E are completely ignored because no 'sibling' could be found for them in the second set.
A third option is Cross Reference matching, which will create all possible combinations: {AK, AL, AM, BK, BL, BM, CK, CL, CM, DK, DL, DM, EK, EL, EM}.
However the best solution in this particular case is not to muck about with the data matching, but instead Graft your data. Grafting means that all the items in a set are moved into their own little set. Thus, if you graft {A, B, C, D, E}, you actually end up with 5 sets, each containing a single item {A}, {B}, {C}, {D} & {E}. When you combine this new data layout with your second set {K, L, M}, each grafted item will be matched with all the items in the second set, this is after all how Longest List works. So you end up with a data layout that looks like this: {AK, AL, AM}, {BK, BL, BM}, {CK, CL, CM}, {DK, DL, DM} & {EK, EL, EM}, which is very similar to the Cross Reference matching, but retains more of the original layout. I.e., it's not just a huge list of all the lines, they are still five groups of three items each, which is a far more informative layout than Cross Reference would generate.
I'm afraid at this time of night this is the best I can explain it.

in with the names translated back into paths. It seems to be fairly similar to the way David's upcoming Geometry Cache that Danny mentioned will function.
Now I just have to figure out what to do with your right pinky!
Secondly, in working with trees in general, I have come up with a number of clusters of my own that simplify frequent tasks. In particular many of them are designed to eliminate the use of the Path Mapper, which I find to be a clumsy tool because it has to be updated every time there is a change in the tree structure fed into it.
Maybe you will find some of them useful. I have attached them all in the definition called "Andrew's Tree Utilities"...
1. Match Path - Given two sets of data with N total items, assign the path structure from one list to the other.
2. Assign Paths - Given a flat set of data and a flat list of paths, format the data items into the specified tree structure.
3. Partial Flatten - Equivalent to a Path Mapper from {A;B;C;D} to {A;B;C}, except it takes an integer value for the number of "levels" to eliminate, and works regardless of the input structure. (i.e. could be {A;B;C} or {0;0;0;A;0;0;B;0;C}
4. Flatten one level - same as above, but defaults to a single level of flattening. I use this one in almost every definition I make.
5. Clip Tree - this reduces a "jagged" set of paths ({0;0} and {0;0;0} and {0;1} etc.), such as are produced by many of the intersection components (the intersections that exist get another level of hierarchy where the nulls remain in the original tree structure) to the overlap among the paths. Equivalent to Path Mapping {A;B}->{A;B} and {A;B;C}->{A;B} but works regardless of the input structure.

your case you can solve your problem using the flatten on both curves and then loft... and copy/paste for every curve XD (this is a really ugly solution).
The loft component and others components, works in lists, and the input geometry (in this case curves) that you want loft, has to be in the same list. If you use the param viewer component, you can see the data structure (list / paths / branches / etc).
With the flatten component you erase and simplify this data structure and put everything in one simple list, if you merge the two curves, youll put both curves in the same list, so you can loft them.
In resume.... do number 3 in this image :D

d-drive or the web or God knows where.
Also, "3 simple spheres" implies that it's possible to determine what "simple" is. Perhaps you really do need 250 components and a runtime of 20 seconds in order to find that single point coordinate that is vital to your design.
An approach which might work but I'm not sure warrants the investment would be to define specific groups of components. Something like "If A is connected to B, then A and B are connected to C and finally C is hooked up to D and E, then you may be able to get the same result using only component X and Y". Not only is this approach free from unknowns it also tries to help the user out. I'd much rather be told "why don't you try using a Key/Value search here?" than "You're a f*cking idiot mate."

into a z-coordinate it just takes one of those values. For it to be an attractor you usually measure the distance (D output). If you plug that into the z-coordinate it will change when you move the attractor point around.
Also you had the option "only draw preview geometry for selected objects" enabled (one of the icons in the top right of Grasshopper). I wouldn't recommend that. It gets very confusing then. Just hide stuff you dont want to see, which is usually everything except your final output. Just middle-click on selected components and hide them. I added a custom preview at the end, which looks a lot nicer than the usual red jelly that Grasshopper shows by default.
Hope that helps!…
