to run at full screen. I've gone as far as using an iPad to use as the second monitor via AirDisplay (which actually works really well) but have never been satisfied with any setup that required you to look back and forth as if at a tennis match all day long.
Not long after first using Grasshopper 3+ years ago I've had the desire for a "Live Viewport" component that would allow a live image of the 3d geometry being generated directly in the canvas. Every once in a while I search the forums with the hope of finding a solution, but always come up empty handed. Someday this might exist although for now I have found what might be the next best thing to a native "Live Viewport" component and its enabled with a small app named Sticky Previews. This app uses the task bar preview feature within Windows 7's aero interface to create custom, floating preview windows from any open window currently running. I've only just discovered the app, but it seems to do the trick and has been stable and problem free so far. -- I will post an update if I find out that I might have spoken too soon. The install allows for a 30 day trial and is $15 bucks to purchase. I just found the app and don't know anything about this group that created the app. If you happen to know of them, Id be curious to find out more.

serveral questions:the first thing is in c++ i have to implement more methods than in my c# test project.
they are:
int MyGhComponent::MasterParameterIndex::get(){ return 0;}void MyGhComponent::MasterParameterIndex::set(int index){ }bool MyGhComponent::IsValidMasterParameterIndex::get(){ return 1;}
i found no hint for the implementation of that interfaces. could someone tell me that is correct ?OK, it works, but is it well writen ? What is the MasterParameterIndex?
the second "bigger" problem is, i want to have an output of an pointlist.X y Z 1.2 1.3 1.12.1 5.2 9.2...
my first approch was to use a
void MyGhComponent::RegisterOutputParams(GH_Component::GH_OutputParamManager^ pManager){pManager->Register_PointParam("Coordinate", "XYZ", "Node-Coordinate");}
and
void MyGhComponent::SolveInstance(IGH_DataAccess^ DA){Collections::Generic::List<GH_IO::Types::GH_Point3D>^ pnt = gcnew Collections::Generic::List<GH_IO::Types::GH_Point3D>(); for (int i = 0; i < 10; i++) { GH_IO::Types::GH_Point3D^ point = gcnew GH_IO::Types::GH_Point3D(i, i, i); pnt->Add(i); } DA->SetDataList(3, pnt);}
but this exampel doesn't work...i wirte a small workaround and use the following
pManager->Register_DoubleParam("X-Koordinate", "X", "X"); pManager->Register_DoubleParam("Y-Koordinate", "Y", "Y"); pManager->Register_DoubleParam("Z-Koordinate", "Z", "Z"); Collections::Generic::List<double>^ pntx= gcnew Collections::Generic::List<double>(); Collections::Generic::List<double>^ pnty= gcnew Collections::Generic::List<double>(); Collections::Generic::List<double>^ pntz= gcnew Collections::Generic::List<double>(); ... add .. ect.
this workaround do the job, but i want a better soulution. and i know somewhere out there sould be a better solution. i want to use 3D Points directly in GH without list conversation.
so somebody a familiar with c++ / cli ? and could give me some tipps or a soulution ?
the first thing is: what is the right RegisterOutputParams ?
and witch data type is the right ? Point3d doesn't work. so i try GH_IO::Types::GH_Point3D and Rhino::Geometry::Point3d ...

I live on my computer and I even sleep with it, so learning all this is probably within my reach but I'm a complete beginner as of now.
I'm downloading the 32 bit version of rhino 5 since the 64 bit doesn't seem to work with your downloads Jon.
I haven't grasped everything you have made yet Jon I can't even begin to understand what your IFC stuff is actually capable of, but just to be clear I'm not interested in solely being able to tell that something is colliding as there are already software that can do that beautifully. What I want to do is bypass that step altogether by never having collision-checking back and forth go on, even collisions which aren't physical collisions, but rather just violations by code. The simplest way to do this would be to simply make the geometry of the beams 2 feet wider than they are in real life, so that way you could put a light right next to the 'over-sized' beam and it would still be within the rules. But that would be extremely primitive and I'm sure there's a way to do it mathematically.
Just to clarify, I'm the fire sprinkler designer in the architectural circus. The sprinkler designer (me) doesn't really get the luxury of telling the other trades that they're colliding with my stuff and they should move. Rather, I get their drawings, find out I'm colliding with them, and move around them. So it would be of great use to me to have this be automatic - that is, to automatically space my sprinklers the neccesary distance away from all obstructions. There are different spacing rules for different obstructions - walls, beams, open web steel, unit heaters, hvac ducts depending on how wide the ducts are, lights, fans, high rack storage, basically anything that would obstruct the water spray from a sprinkler needs to be taken into account and spaced away from.
It's therefore a very attractive idea to be able to just draw a rectangle (representing the walls of a simple room) for instance, have the sprinklers automatically spaced as far apart as possible within the rectangle according to the rulebooks (to minimize the amount of sprinklers needed which minimizes the material cost of the job).
Then add obstructions inside the rectangle, such as a beam, and have the sprinklers relocate themselves or add new sprinklers to accommodate for the new obstruction.. Keep adding obstructions until you have the realistic 3d model of the room, with the sprinklers spaced accordingly, and you have an up-to-code sprinkler system.
There is one example where sprinklers actually need to be spaced really close to, rather than away from, an object.. and that is the ceiling (sprinklers must be within 12 in of ceiling typically).
If the HVAC guy decides to reroute his ducts right through my sprinklers, then I could draw 3D HVAC ducts (I usually get 2D drawings coming in) going right through the room and the sprinklers would relocate and auto-space away from the ducts, without actually having to tell the HVAC guy he is colliding with me because all that will do is require me to do a redesign anyway.
And presto, the HVAC guy loves me because I didn't complain to him at all and seemingly did all this work by moving around him when all I really did was use the computer to do it, the job gets done much faster and I don't have to worry that I'm going to lose my job in court because I made a silly human error when I was patching my system manually because some HVAC guy made me redesign 12 times in different places.
From what I have been reading from you guys, doing this is possible although (I realize) ambitious. The end result would be vastly increased productivity, less error making, cheaper design cost, etc. Using programs like Rhino, architects are getting more and more funny-shaped buildings and making it difficult for guys like me to make sprinkler systems within the rules, and I see it as an inevitability that computers will be making almost all of the typical design decisions in the future when it comes to life safety systems, I'm just trying to see if it's possible to start implementing this extra aid today.

and...how to bake meaningful assembly/component type of structures for the rest of the tedious work required > you know what I mean > the ugly part of our business > documentation drawings, BOM, tech etc etc etc.
For instance, let's focus to the planar glazing support items: absolutely no need to make them it via any smart app since they are plenty of them around in the market (unless you are I.M.Pei and you do that exceptional Pyramid wonder thing).
But...the goal is...hmm...to create some kind of "smart" (kinda, he he) solution where components (the "baked" ones, so to speak) are structured in such a way that further work (via conventional CAD apps) is easily managed. To speak in Rhino dialect: nested Blocks and/or nested Refs. Like having components in GH that could manage nested Block/Ref stuff (but I guess that you can do it rather easily via VB).
Back to that ugly truss: It's obvious that this is a nested collection of "repetitions" (should I call them iterations?) : meaning that a void top node owns a module truss that owns 2 supportive sub-trusses that are made by some pipes that own connecting items that own the planar glazing items etc etc etc.
With regard the "own" thing: Imagine a CAD file that is simply a container/place holder of some individual entities (called Models). These Models can be "linked" to others (in a nested parent/child relation). Links can be external of internal. They can be either References or Cells or Shared Cells. This the way that Microstation classifies/handles "entities" (a bit primitive, mind, but nobody's perfect - for the real thing see CATIA/NX).
Back to that ugly truss: Obviously this structure (actually the assembly/component combo related with the given solution) has to be transfered into classic 2d extractions (say: plans, elevations, sections et all). This is done why a weird thing called Dynamic Views/live markers in Microstation (you define Clip planes in 3d space that manage 2d extraction content in something called Drawing Model that controls other weird things called Sheet Models, all these live linked etc etc).
To make things more spicy...these 2d extractions can been viewed as master detail directives: from where 1:1 classic details are made (that is: you apply more Dynamic Views and live markers and life goes on - red pepper extra strong Russian vodka is a must when you do that type of work).
This is where Rhino is out of his depth (but to be fair: it's not designed for this type of work) and also this is where Microstation has no competition at least for AEC purposes (but to be fair: it is designed for this type of work).
Of course Autodesk...well expect soon the Gen Comp equivalent for Revit...a fact that complicates things (for Bentley) a bit given the Revit mania in the AEC world.
Moral: intelligence is good but it's only the tip of the iceberg. …

project below- should I be learning Grasshopper & Rhino or just Rhino first?
I'm trying to panel modules with low tolerances- I've prototyped regular shapes like geodesics and am now looking to experiment with irregular shapes with lots of different panel shapes.
I understand some things are best done through Grasshopper when using Paneling Tools- I'm trying to figure out if I can do what I want to achive with PT alone or should do it through Grasshopper (or some other route).
I’m on the MAC WIP - The module was built in Sketchup - all the components seem to be in order as blocks though am having problems running the ptpanel3dcustom command - thinking maybe a bug in the WIP or something wrong with my input or that I imported the sketchup file the wrong way. (I dropped it in the window) - If the 3D command is run it doesn’t do anything - if 2D (ptpanelgridcustom) it crashes.
The tileing pattern - the green rectangle is a refrence. each tile contains 4 blocks with 3 more nested in each.
How the module tiles.
The other thing I'm trying to do is specify that most of the lines in the panels don’t bend/curve when they are paneled (or something like Cage Edited). For my purposes the length & angles can change while the lines must remain straight.
These images show a test tile to be panneled on a ellipsoid. When the tile is mapped to the grid the lines curve, this is an extreme example but notice allot of tiles far from the hemespheres are also bent slightly.
These two questions have me stumped the most for now. What should I look into get a better handle on these problem areas? Maybe I should try recreating the work on a windows machine? or perhaps I should get started with Grasshopper?
Thanks for reading.

ts in extreme aliasing effects that carry into the 3D realm as regular steps along what should be smooth surfaces.
On sleeping on it, I realized I hadn't yet tried fast Unary Force on fine quad meshes from the standard Grasshopper meshing system that includes the meshing options component.
Bingo! It's fast now. Workable. I don't need super fine meshing since I'm not running from aliasing. I can still use rather fine local meshes since Unary Force lets Kangaroo do a simple thing just in the Z direction rather than a full 3D force.
After only a minute or so of Kangaroo initialization that slows the interface, each of a dozen needed cycles takes half a second, FOR THE ENTIRE GRAPHIC.
I just set the timer to 1 second so I can move around the interface, and I double click the Windows taskbar timer shut-off to enjoy the result.
WHILE RUNNING VIA TIMER, IF I CHANGE A SPRING/FORCE SETTING IT SUFFERS NO DELAY AT ALL AND JUST ALTERS THE OUTPUT OVER TIME. I can change Unary Force from 20 to 100 and immediately see the bigger areas balloon like crazy:
It's fast enough overall to play with, yet the individual steps are slow enough that it's fun to watch the hysteresis as it overshoots back from 100 to 20 Unary Force, going concave in the middle of bulges then back to more shallow hills.
A force of 1000 is a bit disturbing, I wonder if I can tamp it down with greater spring strength or will that just give me the same result as before?
Looks like it's the same, just the ratio matters. Makes sense I guess. At one point it blew up though. Hitting the reset button...a minute later it blows up again...and just doesn't like huge numbers, so I don't see an advantage playing with bombs. The high mesh strength is pulling the mesh apart.
With low Unary Force and moderate mesh tension, you get flat tops, as if the overall force on the mesh fighting its anchored edge vertices, is enough to displace it, but the surface itself is too stiff to care about local gravity.
Then you have less flat areas as you increase Unary Force:
Weird, there *is* some sort of absolute effects, rather than just relative, between Unary Force and spring stiffness, since now I'm getting flat tops even in the extreme:
Oh, wait, strike that, I may be seeing but a single step with the timer off, subject to hysteresis. With the timer back on...it can sit there a minute...not locked up but just idling...until you see the Display > Widgets > Profiler time start cycling to near half minute numbers...makes you want to hit the reset button...and indeed that locks the interface for another initialization...and yes, it was merely hysteresis, not an equilibrium result. My former flat tops may have been due to that too, due to my use of the Windows taskbar timer disabler. The lesson is that you can obtain different results by using a long timer setting and just stopping it before it equilibrates.
This script is a keeper, fast and fun after the relatively mild Kangaroo initialization period is over.
The uniform mostly quad meshing is all done in Grasshopper too, from any flat surface with holes, especially from images of shapes that are traced with potrace to give surfaces with holes.
Could I switch to hex meshes from triangular meshes to do the same thing with fewer vertices?
Are there other forces I can add to smooth the bulging? Letting things bulge is not so bad if you then just scale down the result in Z afterwards (though perhaps the same result could be had with lesser force):
Also, can this same thing be done with possibly faster Kangaroo 2?…
