he default for Rhino, degree=5 gives you smoother curves, but each control point matters less, degree=11 is the highest degree Rhino allows. Apart from 2, degrees tend to be odd rather than even, though Rhino supports both.
In addition to the degree and the control points, Nurbs curves have knots. A single knot is just a number, and the list of all knots is called the knot-vector of a curve. The number of knots depends on both the degree and the control-point count, and the spacing of the knots affects the shape of the curve a little bit. If there are <degree> knots with the same value, then the curve is somewhat discontinuous at that location which could manifest itself as a kink or as a clamped end-point. However it is not possible by just looking at the shape of a curve to say where stacked knots might be, but you can use the Rhino _List command to inspect all details of a Nurbs curve.…
arget group The workshop is addressed to students of architecture and civil engineering faculties at master level from Estonia (11 seats), Latvia (3 seats), Lithuania (3 seats) and Sweden (3 seats). The selected students will have full scholarship that will include travel, board and lodging in Tallinn for 10 days (arrival on Sunday 03.07.2016 departure on Wednesday 13.07.2016). The workshop is funded by the NORDPLUS programme of the Nordic Council of Ministers (NCM) - Higher Education objective.
Description The use of digital and computational design tools is increasingly important for the activity of design and research for architects and engineers. It permits to integrate environmental and energy aspects from the very early stages of the design and planning process to achieve more performative, efficient and integrated buildings and urban environments. The workshop attendants will broaden their design and technical knowledge with solar design, daylighting and energy efficiency topics and will learn how to integrate environmental analysis and building performance analysis tools with parametric and generative methodologies in architecture and planning.

s the "Surface Populating" definition: I manage to populate my geometry over the surface, but after I bake it, I have to delete the boxes that define my components limits as well! Is there any way of populating and baking only the chosen component, without having to delete the boxes afterwards?
Secondly:
Basically: I am trying to cover a surface with two types of components [ an open one and a closed one] , which will be proliferated over my tubular surface according to the main sunlight direction.
1. I introduce the surface component.
2. I use "Divide Interval2" in order to have division into U and V.
3. i generate the target boxes [ "surfaceBox"] .
4. I use "Isotrim" ( same intervals) and "BRepArea" to find centroid of each area.
5. My "Curve" component introduces sun angle, with its "End Points".
6. I use "Vector 2Pt" to specify sun-light direction.
7. I want to measure the angle between sun-light and the surface normals, at the position of each component; after generating the centre points, I need the normals of each centre point to get the surface's points' UV, and "Evaluate" the srf at points.
8."Angle" and "Vector" components: I use them in order to evaluate the angle between the sun direction and the srf.
9. I convert this angle to degree by using a "Function" [ to see if the angle is bigger from the max.angle or not...]
10. Function "x,y" gives me boolean data.
11. Data become "Dispatch"ed...
12. Two "Morph" components , each one linked to one part of the "Dispatch" data, generate "closed" and "open" components over the srf.
The result should have been different types of components, based on the surface's curvature, diraction and sun-light direction...
I do not understand where the mistake is in this definition...
Thx in advance1

ells new products like the Firefly Interactive Prototyping Shield which mounts on top of your Arduino Uno and provides access to a number of useful input (ie. sensors) and output (ie. motors) devices. It includes features like:
Three linear slide potentiometers connected to analog pins 0, 1, and 2
Two-axis joystick connected to analog pins 3 and 4
Light sensor (photocell) connected to analog pin 5
Three push buttons connected to digital pins 2, 4, and 7
Red LED connected to digital pin 13
RGB LED connected to digital pins 3, 5, and 6
Two servo connections on digital pins 8 and 9
A connection to the Easy Stepper Driver (co-designed by Sparkfun Electronics and Brian Schmalz) to control stepper motors. The direction of the motor is controlled through digital pin 10 and the number of steps through digital pin 12
High-voltage MOSFET circuit capable of driving lights, valves, DC motors, solenoids, or anything else requiring higher voltage or current. The gate of the MOSFET is connected to digital pin 11 (PWM).
Some come take a look and let us know what you think!

lane that looks like the outline of a gear wheel
2. Scale a bunch of copies of the curve to different sizes (I use 11 different sized curves.)
3. Move each curve vertically to a different Z-height
4. Rotate each curve to get the desired wavy/wiggly effect
5. Create a Loft surface using all the curves.
A critical step when creating the Loft is to add the curves in order - either top to bottom or bottom to top.
Step 4 can be omitted if you want a constant curvature throughout the final part. In this case all you have to do is Twist by the desired amount the Loft surface made from un-rotated curves. …

ings" [every person on the experiment is one ring] which show the time duration. The outer sphere is divided in 11 segments [which are basically the segments of a human brain] I hav imported the data so far but what i aim is to find a way to connect each moment[time, second] from the inner sphere to a number of points from a specific segment in the outer. For example for Person number1, at 5th second the segments that are activated are 4th , 6th, 11th with 2, 3, 2 points.
It could be done manually but since the connections are a few thousands and i got the lists, i wonder whether there is a better way.
Any help is appreciated, i do not attach files since you need the excel files aswell. If anyone would like to help i can email the files.
Thanks in advance.…

Loop'. The fun part of the slower version is that you can see what it's doing while it's running. 'Fast Loop' gives no indication that it's working, so you want to test it with small numbers and be sure it's coded properly before bumping the iteration count up.
The GH profiler running the slow version showed between 1 and 1.5 seconds per loop, but the reality was more like ~10 seconds per loop toward the end of an 11 X 11 grid, or ~20 minutes total. It's easier to be patient because you know it's working.
The 'Fast Loop' finished the same grid in 1.6 minutes! An impressive improvement. I've been running it on a 30 X 30 grid (900 points) for ~23 minutes so far and see nothing yet. Not the ~12 minutes I had hoped for... Now 36 minutes on this loop for 900 points... hope it's not stuck. Not fast! Later - DONE!! Profiler says 59 minutes for 900 points but it was more like an hour and twenty minutes total. It succeeded, I have a single 'Closed Brep' from 900 extruded rings, baked to Rhino.
Another strategy to explore would be doing 'SUnion' on a smaller grid using the Anemone loop, then replicate it by moving it as needed to form a larger grid; then run the copies through another 'SUnion' loop. I went ahead and implemented that while waiting. It works and is fast! Started with 3 X 3 and ran the result again as 5 X 5 (9 X 25 = 225 total) in barely ~70 seconds!? Trying 36 X 36 now... 1,296 points appears to have succeeded in less than ten minutes! Though it seems to take quite awhile after the loop ends before control is restored to GH/Rhino. I'll let you do your own experiments and benchmarks.
I encapsulated the loop in a cluster called 'suLoop' (blue groups).
Internal of 'suLoop' cluster:
