Comment on: Topic 'COM class factory issue': rights to register the "mapwingis.ocx" file.Francesco, would you be patient just a tiny little bit, so that we could try something else? I would be grateful if you could. 1) Close Grasshopper and Rhino2) Run the Revo Uninstaller Pro and uninstall your MapWinGIS application along with removing all the leftovers from the registry.3) Restart your PC, and once it boots again, make sure that you are logged in as an Adminstrator.4) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".5) Turn off your Antivirus, which ever it is.6) Download the 64 bit version of v4.9.4.2 MapWinGIS.7) Right click on downloaded MapWinGIS-only-v4.9.4.2-x64.exe file, and choose "Properties". If there is "Unblock" button click on it, and then click on "OK". If there is no "Unblock" button, just click on "OK".8) Left double click on MapWinGIS-only-v4.9.4.2-x64.exe file and install it to "C:\dev\MapWinGIS" folder. Choose "Full installation" during installation process!9) In your Start menu's search box type: "CMD". Once the "Command prompt" appears do not left click on it! Instead right click on it, and choose "Run as Administrator".10) A command prompt window will open. Type the following command: "your_regsvr32_folder_path\regsvr32.exe" /u /s c:\dev\mapwingis\mapwingis.ocx If command does not result in an error message, then type this one afterwards: "your_regsvr32_folder_path\regsvr32.exe" /s c:\dev\mapwingis\mapwingis.ocx 11) If no error appeared again, then open your Rhino and Grasshopper and check what Gismo_Gismo component prints from its "readMe!" output.If errors appeared, it would be nice if you could post their screenshots.…; Added by djordje to Gismo at 5:46am on March 27, 2017

Comment on: Topic 'feedback': ges can have much stronger impact on the final design. The problem is that usually the more "nonlinear" the mapping is the more interesting the result usually are because a definition with a very "linear" mapping doesn't have so much potential for surprise and unforeseen solutions. It can be a random number as you stated, but also some like for example a slightly different point coordinate leads to different typology in a delaunay triangulation, now the strength of the impact also depends on the total sum of the delaunay points as well on how early the triangulation happens in the definition. I seen that a shape analysis is a not easy at all not only technical but especially by defining the criteria. Looking forward to see your approach compare genotype and phenotype 'solution' spaces. Maybe an additional approach could be to have something like a gene manager where you can narrow down ranges of certain genes, weight them or freeze them. to 4) and 5) looking forward to see the history once its ready. I think it could be beneficial to also be able to insert solution "by hand" for further crossbreeding and saving. What i found myself doing quite often was taking solutions from the biomorpher and then tweaking one or more parameters "by hand" because then you can really see the impact and then you would like to have the possibly to bring that solution back into the biomorpher process. I will go on testing and get back to you guys in some weeks! I attached you the my definition in case you want to have a look. Its needs kangaroo1, lunchbox, heteroptera and wb.

Comment on: Topic 'Mesh an irregular surface for further structural analysis purpose': achieving some preliminarily/conceptual Academic solution that "may" qualify as "realistic". I have several defs that do similar stuff ... but this is an Academic forum and as you can understand a real-life solution would never appear here. But let's forget the W task (truss out of relaxed mesh with depth, known as W in our trade). See for instance a step prior the "thickness". General guideline: 1. Create a boundary (a BrepFace) and attempt to do some "reasonable" Mesh via Mesh Machine. 2. Mastermind a policy to manage anchors (naked and/or clothed vertices). This appears easy but is impossible without code IF you want to do it interactively. 3. Separate naked edges from clothed ones (as we do in real-life in tensile membranes etc etc) in order to apply different goal parameters. 4. Relax the mesh (K231 engine). 5. Either work with a "geodesic" structure (W = 0) or make a truss out of the mesh in 4. In either case decide the real-life system in use (say a Mero KK or some other). 6. Check clash truss members issues and interactively vary vertices in order to resolve them. 7. Create all the required connectivity Trees (VV, VE, EV). 8. Mastermind the skin solution (only for experienced pros: avoid at any cost that one). My advice? Unless you are very determined ... well ... what about choosing an easier design task? …; Added by peter fotiadis at 3:25am on November 9, 2017

Comment on: Topic 'Mesh an irregular surface for further structural analysis purpose': of similar/WOW buildings that failed (or leaked) including a very famous one. 2. You must use instance definitions for the truss parts (sleeves, cones, rods and the likes) otherwise the whole thing could become an unworkable nightmare. 3. You must address clash issues otherwise doing it is out of question. These affect the skin parts as well (but as I said: this is 100% pro territory). 4. Your structural analysis (in order to make any sense) must deal with real life components either commercially available or bespoke things designed for the specific project. 5. Wind/Seismic effects can cause skin component issues/failures/leaks as it happened ... well ... in a variety of contemporary famous buildings. 6. Vapor condensation yields (in most of similar cases) buildings that "rain from the inside" - nothing serious, mind: just have an umbrella ready. …; Added by peter fotiadis at 12:51am on November 10, 2017

Topic: New ShortestWalk for Grasshopper: ge curves. The source code is available as usual on GitHub, https://github.com/mcneeleurope/ShortestWalk. Here some examples of walks on predefined and custom grids. With equilateral grids (1, 2, 3), the shortest walk on the network is the same both counting the edge length and the number of links. With these types of grids, there are often several solutions, one of which is selected by the ShortestWalk component. If the automatic search is used (no lengths are specified), then the A* algorithm is used and this will result in a path that departs "not much" (there are more rigorous definitions) from the straight path. With the square grid (2), the geometry is called taxicab or Manhattan, and results in the total distance being the sum between the number of vertical steps and the number of horizontal steps. The circular grid (4, 6) shows a case in which curve distance and "link distance" (number of edges that are walked, uses Dijkstra's algorithm) results is completely different paths. This example here selects the tangential road (4) or the "city center" (6). Finally, Voronoi diagrams (5), Delauney triangulations (7) and random mazes or labyrinths (8) can be walked, searched and solved quickly, if a solution is possible, now even if there are multiple overlapping curves. These examples show two-dimensional grids, but it is possible to also compute (weighted) walks on three-dimensional networks. The compiled Grasshopper assembly (.gha) and the examples can be downloaded from Food4Rhino.

Topic: Data management and rewrite problem: branch. The weird part is that when I add stuff to the "trail" branch, the path "p" gets rewritten, and if I comment(trail) out it maintains its proper structure. The structure normaly goes{0;0}-{1;0}-{2;0} and so on, when I enter the if statement it should be {0;0}-{0;1}-{1;0}-{1;1}-{2;0}-{2;1}, but what I get is {0;0}-{0;1}-{0;2}-{0;3}-{0;4}-{0;5} The code in question is bellow(it is a part of a bigger whole). For i As int32 = 0 To trail.BranchCount - 1 For j As int32 =0 To trail.Branch(i).Count - 1 Dim ghi As GH_Path = trail.path(i) Dim v As Vector3d = vL.Branch(i).item(j) Dim pw As New Polyline(trail.Branch(i).item(j)) Dim agent As New point3d(pw.Last) Dim p As New GH_Path(ghi(0), ghi(1) + 1) v.Unitize v *= seg agent += v If (count Mod math.Ceiling(conrate * div) = 0) AndAlso _ (stopper.Branch(i).item(j) = 0 AndAlso count > 0) Then print(p.ToString) Dim dupPw As New polyline duppw.Add(pw.Last) duppw.Add(pw.Last + v * seg) vl.Add(v, p) gen.add(gen.Branch(i).item(j) + 1, p) stopper.add(0, p) stopper.Branch(i).item(j) = 1 trail.Add(duppw, p) Continue For End If pw.Add(agent) vl.Branch(i).item(j) = v trail.branch(i).item(j) = pw NextNext I am looking foreward to hear any suggestions.

Topic: Reconstructing Tree Structure from Object User Dictionary: n #, row #, seat #, various value metrics, etc.). I can also use Elefront to bring this data back in along with the geometry, but the geometry comes in flat. Normally I would grab a corresponding tree structure from somewhere upstream in the definition or internalize the structure if I'm starting a new definition and then apply this to an unflatten component to restructure the geometry. However, I got to wondering if I could use the flattened row and seating data from my object's user dictionary to reconstruct a tree. To keep things simple, I start the numbering at 0 instead of 1 to match the way Grasshopper indices work. If I have 2 sections, each with 3 rows, and the rows have 4, 5, and 6 seats respectively, my seat data per seat would look like this (spaces are for pattern clarity): 0123 01234 012345 0123 01234 012345 And my row data per seat would look like this: 0000 11111 222222 0000 11111 222222 I was able to use these two numerical patterns alone to reconstruct the tree but I suspect my solution is inefficient. I'm including images and the definition itself in case anyone wants to take a stab at it. …; Added by Brian Ringley at 3:13pm on October 9, 2014

Topic: Questions / Suggestions: ight. Note that i added the Ladybug component to simplify the inputs... Here are some functions i'd love to see: 1. Ability to cull down to a partial year / date range AND hours range. Currently the DSchedule component can only truncate time of day. But if for example i want to look at averages just during the summer months between 9am - 6pm, i have to do that in the excel .ill file. It seems that the components may allow this already, just not sure which settings need to be set (seems that the reporting frequency has something to do with this...) 2. I'd also like to be able to look at a subset of the points to look at averages in a part of the grid. The easiest i presume would be just to pull item #s; maybe there's a way to add visual identifiers to the selection option? Again, have been doing this in the .ill file. 3. Provide, as an alternative to the .pts file, the option to input the point geometry directly from the rhino file - maybe this would help with #2? 4. I read up on your explanation on showing point-in-time values but can't seem to get that working. Would love to be able to do slider animations of the point-in-time calcs over a day like the bottom right of this (here i used Ladybug but the DA output would be more accurate). 5. Visualization Bounds doesn't seem to work on the daylighting side - would like to be able to manually change. 6. Showing the peaks is a fantastic addition! But all that information is bundled in the python script - would love a way to parse it out to just show the peak numbers for example. 7. Similarly to how DIVA shows data, it'd be great to add a component that visualizes the simulation parameters and color scale in the Rhino viewport...:) i'm sure there's more as i continue to use it... great script. dan …; Added by Dan Weissman to Mr.Comfy at 12:02pm on October 15, 2015

Topic: Project a building mass onto plane along view lines: o far (abstracted for brevity) have been: 1) decompose the brep to extract the faces for each cardinal orientation 2) Extract the corner points of these faces (my script here is a little rough - would appreciate feedback) 3) Draw lines from these corner points to a curve that represents the sidewalk on the other side of the street 4) intersect these lines with a plane 5) draw a Polyline through these intersection points (using a clever bit of VB written by David Rutten) 6) Make a surface from this polyline that represents the perceived building mass as seen from the sidewalk on the other side of the street. This seems like it should be simple, but I'm struggling to make it work for every facade of the building, and for any geometry I throw at it. So far I've been successful for one facade of the building, but my script breaks down for the other facades. I think the breakdown lies in drawing the polyline between the intersection points - though I may have created this problem earlier in the script in my corner point extraction strategy. Working Script: Broken Script: I'm writing this script to allow me to analyze many building massing options in a short amount of time. I'm trying to make it work universally for a large range of geometries. Any help you can provide would be awesome! I've attached the script and the rhino model. I've done my best to annotate the script and highlight the area that I believe to be broken. Thanks, Matt …; Added by Matt Bowles at 11:53am on June 16, 2016
