yet accessible features that have been well factored.
I’m impressed with the mainline experience overall. BUT, and this is a huge but, Rhino5 has an absolutely massive bug right in the middle of the engine. I, of course, refer to the Boolean Problem. I’ve put the product down cussing 4 times already after realizing that I’d just lost 3 hours trying to figure out why something doesn’t work, only to realize that I’m up against yet another derivation of The Boolean Problem.
I’m written McNeel tech support about the issue. They’ve offered file-specific workarounds in response. But these workarounds don’t allow a solution that can be used resolve generalized characterizations of the bug in Grasshopper programs. Brian, the support tech I’ve dealt with on this problems goes on to say that I shouldn’t expect any significant fixes for this problem.
I’m shocked that major revision 5 of a seemingly mature product as Rhino is has such a gigantic, mainline bug in the very core of its engine. But even more surprising is Brian’s suggestion that perhaps I’m just not ready for a product like Rhino. He further suggests that I post, as I’m doing here, to see what other people think about this bug.
So what am I missing? Where do experienced Rhino/Grasshopper users find themselves on the continuum between this being a big hairy bug that should have been fixed long ago and my just not being ready for Rhino?
I’ll accept any input and consensus that prevails.

I have the IES files from the manufacturers. I am able to get the IES files to load and run in Honeybee. However the light levels being produced are low and very localized to the light source. I am trying to determine if it’s some scaling, etc that needs to be modified. Within Honeybee there is a “CandelaMultiplier” which allows me to increase the values, but I don’t want to do it arbitrarily nor am I sure this is truly solving my problem.
If anyone has any insight as to importing IES files into Honeybee and things that need to be factored and considered that would be appreciated. I'm experiencing the situation with other IES files as well.
Thank you!

an almost planar tissue (your case) can cause a variety of issues up to the undo able state (metal parts/components grow in size as well for no reason). See forces estimated by FF below.
2. Therefor I strongly suggest to consider Plan B (a) mastermind a secondary "anchor" capability in order to achieve a far more stable system (b) use a mount design that can support this (and comply with the attractor concept of yours). Here's a variable mount custom system (mostly machined AND not cast) that is suitable for the scope (Rhino reads the stp file OK .... but makes a colossally big file - thus I attach here the original).
3. On first sight lot's of things in this system appear "odd". For instance: is it stable? Why these double cables are used? How far can be adjusted? (that's a classic case for feature driven parametric design - not doable with Rhino).
4. This concept (strut axis exported only) is tested in FORMFINDER and some other far more complex membrane apps that I use quite often (not RhinoMembrane). Here's is what FF tells us about:
Observe a different kind of "stress" when this is converted to radial type:
5. If you insert the stp file to the Rhino file provided (exactly as exported from FORMFINDER - no mods of mine of any kind) you'll see what goes where (and why). That way the usage of double cables is rather obvious (and a lot other things - for instance the way that the struts achieve "equilibrium", see the slots in the base mount plate.
6. If this approach is worth considering your definition requires some serious rethinking (far more simpler/manageable with the drawback that the real parts they are "static" they can adjust only as far this particular solution allows them to do - controlling them parametrically is clearly impossible with the current state of R/GH capabilities).`
All in all: this case works because the cables push the anchor points downwards and the struts push them upwards.

reaky thing consisting from triangulated "modules" (i.e an assembly out of this, this and that) where the exterior edges ARE always under tension (= SS 304/316 cables OR nylon) and the interior ones MAY be under compression ( = steel, aluminum, wood, carbon) OR ... some of them ...may be under tension. Bastardized T trusses deviate a bit from theory ... but who cares? (not me anyway). T trusses have many variants (but as the greatest ever said: Less is More).
2. Large scale T for AEC is the art of pointless since it costs around the GNP of Nigeria. Here's some indicative components from a module of a multi adjustable TX system costing (the module) ~ the price of my Panigale (Google that):
The above is mailed to a friend who has MIT (yes, that MIT: the top dog) on sight ... therefor he needs some appropriate "credentials", he he.
3. The distance that separates the above with the demo TDT node provided is around 666.666 miles - but we don't care: we are after Art not some testimony to vanity.
4. On purpose I've used a smallish ring to give you a clear indication upon the constrain numero uno in truss design: CLASH matters.
5. You'll need:
(a) A decision related with the tensioners (classic Norseman + SS cables or nylon machined thingies?).
(b) A machinist who can do elementary stuff (like the adapters) and can weld this to that (the "ring" for instance). His abilities must be 1 in a scale of 100. If the fella has a computer (not a CRAY) and he knows what 3dPDF is (hmm) ... well ... use that way to communicate with him PRIOR designing anything: He must agree on the parts BEFORE the whole is attempted (as a design in GH or in some other app).
(c) A carpenter with a wood lathe for the obvious. BTW: BEFORE doing any TDT attempt > ask the carpenter about the available wood strut sizes. Against popular belief DO NOT varnish the wood (use exterior alkyd/oil stains from some top maker like the notorious US company PPG).

(d) Good quality cigars (and espresso) plus some classic music (ZZTop, PFloyd, Cure, Stones, U2 etc etc) during the assembly.
(e) Faith to the Dark Side (see my avatar).
May the Force (the dark option) be with you.…
the following image of a hut.
I do not have experience using kangaroo to simulate forces, but I have made a test using multiple random components on a flat surface to fake the effect I'm going for. See image below.
The main issue I'm having is that the original file used for my test surface used box morph and the variable pipe command. Box morph is a bit touchy on a curved surface and it is not as elegant as I would like it to be (ie. I want all the hair diameters to be perfectly circular and uniform in size). Variable pipe also does not align the base of the hair with the existing surface, which means I have to offset the surface and then trim the excess of my pipe.....leading to heavy code and the file crashing.
So I'm trying to rebuild the "hairs" using a new method:
1) Subdivide the surface
2) Find the midpoint of each surface and then create a straight line that is perpendicular
3) Move a point along the on the straight line (between the start and end points) in the z direction, and then create a nurbs curve using this point and the start and end points
4) create a circle at the base of each crv, and then two more circles: one at the point in the middle point (I think I set it to .9) and the end of the curve
5) The problem: Now I am trying to sweep along these three circles and the nurbs curve to create a bent hair/pipe that is flush with the conic surface, but it does not work.
If someone can help that would be amazing. I've included my original surface test file and my new file where I am rebuilding using the sweep command. Below is a drawing of what I'm trying to achieve.

ly 26-27-28-29 (digital fabrication)
The third edition of digitalMed Workshop is structured as a design laboratory. Participants will learn the challenging process of producing ideas, projects and research analysis that are to be developed through specific software and concepts that emerge through the use of mapping, parametric design and digital fabrication.
The workshop will take place in the city of Salerno (Italy) and it will last 11 days structured into 3 intensive weekends: July 13-14-15 (mapping); July 19-20-21-22 (parametric design); July 26-27-28-29 (digital fabrication).
Goals and Objectives:
We aim to make clear the theoretical and technical knowledge in the approach to parametric and generative design and digital fabrication. (From collection and data management, to the manner in which these inform the geometries, to the fabrication of prototypes.)
Participants will also have the opportunity to practice the new knowledge gained in the design laboratory through project work.
Project Theme:
"Urban Field" Identify, study and analyze the system of public spaces in the urban area of the city of Salerno.
Connection, mutation, generation and evolution are the themes to be followed in project work.
Brief Description of Topics:
- Mapping. Our reality, in all its forms, has studied through concepts of the theory of Complex Systems. The techniques that will be used to study events and places of reality, will work for the management, manipulation and visualization of data and information. These will form the basis for project management and driven geometry, conducted during the second phase of the workshop.
- Parametric Design. Introduction to Rhino* and Grasshopper. Specifically, we will explain the concepts with which to work with the software of parametric design and how they function. Through these tools, we will arrive at the definition of systems of mathematical and / or geometrical relationships that are able to generate and govern patterns, shapes and objects that will inform the final design.
- Digital Fabrication. In this phase, participants of the workshop are organized into working groups. Participants have access to materials and conceptual apparatus that will take them directly to the fabrication of the geometries of the project, with the use of software CAD / CAM interface and the use of machines for the digital fabrication.
The DigitalMed workshop is organized by Nomad AREA (Academy of Research & Training in topics of Contemporary Architecture), in collaboration with the City of Salerno, the Order of Architects Province of Salerno and the National Institute of Architecture In / Arch - Campania.

case for sure (started by Giorgio a couple of days before). Ive got involved because I exploit ways to "relax" shapes on nurbs (say patterns created by Lunchbox or "manually) without using any kind of mesh (more explanations soon).
Here's 5 test cases (SDK appears that doesn't have some "thicken surface" thing ... thus the algo that finds the "whole" shapes is rather naive) VS 2 Kangaroo "methods" and the why bother (he he) option as well.
If the goal is to "fit" these shapes within the nurbs ... does it work so far? No I'm afraid (appears that "springs" used are not the proper ones - or [Kangaroo1 option] the lines that pull should been originated from valance 2 points only)
Tricky points:
1. Internalize appears having a variety of serious issues (see Input inside definition) - Load Rhino file first (but even so ...).
2. Pull to surface is deactivated - this is not the issue here (and it's very slow).
3. Since Starling/WB alter the "curves - points" related order
the issue here (Pull points to curves) is to correspond apples to apples:
and that's what Anemone does:
From chaos :
to order:
this means that prior activating Kangaroo you should double click to the Anemone start component in order to "sort" properly the curves.
But .. fact is that results are pathetic:
more soon
best, Peter…
