Comment on: Topic 'Therm': simple box of Aluminum, I expect an almost similar U-value and lambda, (not equal due to radiation and convection transfer) if the box is 1 m length. But the amounts are very very different. While Al- lambda is 237 W/m.k , Therm calculates the U of the assumed box 4.59 W/m^2.k . I guess this is because of my mistake in assumption of Hc factor, which I don't know how it should be defined. the assumed Boundary condition for therm calculation was: (interior boundary Hc = 4.65 W/m.k and temp=21 centigrade exterior boundary Hc = 10 W/m.k and temp= -18 centigrade) If I put 237 for Hc of both exterior and interior boundaries, the U-value would be 79.47 W/m^2.k.…; Added by Farnaz to Ladybug Tools at 1:26am on May 15, 2016

Topic: Controlling Surface Division: e into SubSrf based on an equal number of UV intervals. My thought is to have the SubSrf's divided based on a given ratio rather than equal segments. For example, Let the number of V divisions remain 1. The U interval would be calculated based on the average V height of the U Interval. I want to set the function of the U interval to V/3 or something similar. We could have a problem if it is done linearly and the last interval is too short or too long. Possibly it could be done based on a weighted average so that the 'extra' space is averaged into the other intervals. I made a sample drawing of what I am trying to achieve. See the "adjusted" version. The sections are made proportionally rather than equal... Any ideas or sample grasshopper files?

Comment on: Topic 'Is Mesh Coordinate Precision Single?': on floating point numbers that are used every where else. Its more or less, just using a slightly less accurate number to save space. If you dig deeper, you'll find that the vertices are actually a different class than normal points... On3fPoint as opposed to On3dPoint. Does that cover it?…; Added by Damien Alomar at 8:30am on September 23, 2009

Topic: Points definition and points array in VB.net: tion and the points array that follow. I was used to the Rhino.EvaluateSurface(Strobj, ArrParam) to pick pints on a surface. Then I understand that points are identified with var pt and added with function pt_list.Add(pt) . But can't understand the whole syntax. This code is supposed to create hexagons!
