ike this, and more specifically about Lofted geometry, is that if you give the Loft function a bunch of complex curves to match the edges of, the resulting Loft surface does not always match the curves used to make the surface. If you have 2 Loft surfaces that meet at the same curve (for instance, when picking the top curve of an inside and outside Loft surface to make a closed lip), the connection between them will have tiny gaps in various places. I attribute this to truncation and/or roundoff errors in calculating the Lofted surfaces.
However, it seems that using the Cap function actually eliminates this problem by turning an open Brep Loft into a closed/solid one. Of course I have no idea why this happens, but it does eliminate naked edges, edge gaps, and any other weirdness associated with joining Loft surfaces.
Before discovering this method I spent about a week trying all the suggestion you mentioned. None of them worked. All of the Join functions failed, different meshing parameters had no effect, and Mesh Smooth and Weld did not help either.
In pretty much all of these cases the 3D Builder app that I use for fixing/simplifying STL files exported from Rhino would run for a very long time, forever, or add artifacts (like a closed top) that rendered the part unprintable.
I have changed my GH layout to incorporate the Cap/SDiff functions now, but if you' like a 3DM file that uses the previous method I can certainly go back and create one for you.

d as a mask). By inputting the # of grid points in the Y direction, it calculates # of grid points in the X direction, trying to create as close as possible a square grid division.
Hovering over the surfaces are 2 curves. By calculating the distance between the curves' points and grid points, an attractor pattern is created.
The source object is scaled based on the attractor curves, flipped upside down and adapted to the surface normal. Finally a solid difference is applied resulting in the indented surface pattern.
(Also, there is some more detailed input regarding object size, rotation and location.)
While running this on a machine with enough processing power to fly me to Mars, Grasshopper still becomes really slow and unresponsive ever since I've added the sDiff component. The same goes for utilizing the Trim component instead of the sDiff (I assume they do the same in this scenario?).
Am I missing something here? Is it somehow calculating large amounts of unnecessary data? Am I doing things overly-complex?
Attached the Rhino & Grasshopper files. Please play with the "# Objects in Y direction" slider, to (hopefully) experience what I mean. I am looking at a preferred # Object in the Y direction upwards of 50 at least. Changing the "3D Object" BRep to something else (in the hidden layers) might also influence performance.
So, what do you guys think?…

ally to describe a process of repeating objects in a self-similar way. Simply stated, the definition of a recursive function includes the function itself. Fractals are among the canonical examples of recursion in mathematics and programming. A loop can simply be a way to apply the same operation to a list of elements, but it is an iterative loop if the results from one step are used in the calculation of the next step. In design research controlling recursion becomes a new strategy to define new forms and spaces.
BRIEF
In this workshop we will be exploring iterative strategies through parametric design. Main tool for the course will be grasshopper3d and its add-on Anemone. Anemone is a simple but effective plug-in for Grasshopper that enables for loops in a simple and linear way. We will explore several strategies such iterative growth, L systems, fractals, recursive subdivisions and more. Our course will focus on how those methods can affect three-dimensional geometries, generating unexpected conformations.

The workshop is open to all participants, no previous knowledge of Rhinoceros and Grasshopper is required (although an introductory knowledge is welcome). Participants should bring their own laptop with a pre-installed software. The software package needed has no additional cost for the participant (Rhino can be downloaded as evaluation version, Grasshopper and plugins are free). These softwares are subject to frequent updates, so a download link to the version used in the workshop will be sent to the participants a few days before the workshop.…

ystem to support it from the back.
ELEVATIONPLAN
What I need to do is create a mesh network that is composed of straight segmented pieces. To start, I contoured the surface at 500mm segments in the X and Y axis, getting a mesh grid [below]
Then, I wrote a simple grasshopper script to segment the contour lines, but when I run it, the segments in the X direction and the Y direction do not intersect like I need them to.
I understand why this happened and I understand what I need to do (in concept) but I can't seem to figure out how to implement it.
I'm pretty sure that I need to take the original contours and find the intersecting points and include it in my set of points from DivLength command. My problem is that in the list, the numbers get all jostled up and when I Pline the list of points, it goes a bit crazy. My questions are:
1. Is this the best method of going about this process of creating the segmented mesh?
2. How do I reassemble the list of the two point groups I added?
Thanks in advance!
Best,
Issac

e a critical environment for speculation on the possible transformations of the contemporary human body.
The workshop focuses on the research of geometrical explorations, aesthetic behavior of generative patterns and material performance through medium between computational design, digital fabrication and traditional sartorial techniques in haute couture fashion.
By integrating Design, Fashion and Architecture, the relationship between digital patterns and the human body will be crucial in order to adopt a contemporary language and translate it to a design that is both functional and physically appealing.
In Biology, tissues are organizations of similar cells that are composed of organs and living organisms. Due to the specific qualities of singles cells, some peculiar functions of the tissue emerge; conditioning its effectiveness and determining its’ contribution to the life of the organism. The same biological principles can be applied to any design: when the designer explores these particular parametric strategies, it is important to work with a tool that provides efficient feedback and allows one to easily introduce a wide range of variations leading to significant qualities for a design evolutionary process.
The workshop aims to produce full human scale 1:1 prototype wearable garments, in which will be exhibited during Milan Design Week in April 2017 at SBODIO32 Exhibition.
Dates: 18th April - 23rd March 2017 Tutors and Professors: ALESSANDRO ZOMPARELLI Designer and co-founder of MHOX STUDIO 3D Modelling for Product Design Professor at Academy of Fine Arts in Bologna Member of Co-de-iT Developer of Tissue, plugin for computational design in Blender FRANCESCO ANTICI Fashion Designer and Director of ARCHilista ALESSANDRO TURCI Professor of Fashion Publishing at Brera Academy and IED Milano.

S of elements (chain links in this case), work first at low resolution to reduce compute time and avoid freeze-ups! When the model looks right you can increase resolution (i.e., the number of contours/links in this case).
The first effort (chainmail_2017Jan18b.gh) is getting points at the intersection of contour lines from two planes, XY and YZ, then getting surface normals for those points to 'Orient' the pair of links. This required ignoring all the extraneous points (due to multiple surfaces making up the "polysurface") returned by 'Srf CP (Surface Closest Point)' using two criteria: the 'D (Distance)' value and the 'uvP' coordinates that indicate an edge point (x=0 or 1, y=0 or 1).
Using the YZ plane worked well for the front and back surfaces but results in sparse points on the sides. Using the XZ plane instead has the opposite effect. Would be great if they could be blended somehow (animated gif):
Ultimately, it would probably work best to treat the body section and the arm as two different cylinders with contours conforming better to each surface separately.
The second method (chainmail_2017Jan18c.gh) uses only XY contours and 'DivLength' (divided by length), similar to a brick wall:
