Something like this should do it 1. Graft a list of input breps 2. Find a the area centroid of each object 3. Construct vectors from the centroid points to origin (0,0,0) 4. Move all breps to origin on this vector 5. Make x vectors of different…

Hi, I'm also interested in leon's problem. how to position breps center points on a given point list or grid is there a component we can feed with center points on one inlet, and with 3d shapes in an other inlet. Thanks for any clue.

Hi Axiom, OnBreps have a Rotate method as well as a Transform method. If you can get away with using one of the overloads of OnBRep.Rotate() I suggest you follow that route. In either case, rotation origins are just regular points, and rotation…

Hi Dirk, Thanks for getting back to me. I had managed to find a bit of a work around but it involved me doing a lot more manual calculations. I will try this code as soon as I get a free moment. Thanks again

Dirk Anderson replied to Axiom's discussion 'Rotating Breps in VB.net'
you need to determine which is the bottom surface and then use a centroid of the brep.Face().NurbsSurface as an origin point. See code below to work extrapolate the surface and centroid. Private Sub RunScript(ByVal inContext As List(Of OnBrep),…

Rotating Breps in VB.net

Hi everyone,I am wondering how to select the origin point on which a Brep is rotated in VB.net? The Breps I have created are just boxes and i would like to be able to rotate them on the y axis from the centre of the bottom surface.I have had a look on the Grasshopper Primer V2 and found the code "rotate.Rotation(angle, OnUtil.On_yaxis, OnUtil.On_origin)" but I don't know how to change the OnUtil.On_origin to the centre point of the base surface.Any help would be very much appreciated.See More

Hi David, Thanks so much for your help, it worked perfectly. I didn't realise that the points needed to be a motion vector. Thanks again.

Hi Axiom, we actually have a separate forum especially for VB and C# questions, you may consider posting there to avoid confusion. Moving objects in the Rhino SDK often works in 2 ways: 1) Some object carry a Translate() function, which takes a…

Moving objects in VB.net

Hi Everyone,I'm new to VB.net and really hope someone can help me out. I have managed to create a Vb script that outputs a list of Closed Breps and another that outputs a list of 3dPoints. What i would like to do is use the list of 3dpoints to position each of the Breps. i.e the first brep would be positioned by the first point in the 3dPoint list.Does anyone know how I could do this VB.net? Even knowing how to move Breps in Vb would be a great help.Thanks in advance.See More

Hi Axiom. One rough thing I can think of would be to have your selected values in a list of integers (being those positions in the main list you would like to process) and call them in a loop. In pseudocode: Sub RunScript(ByVal Mainlist As List(Of…

Hi, Thanks so much for putting that GH file together and sorry for the late reply. I am having some problems inputting the data into a function F(x) as it keeps going red (is the data not suitable to be used in functions?), but I realize this is…

Hi, Sorry for the slow reply... Is this the sort of thing you mean? It's a basic read-out of the XYZ co-ordinates of each point on the surface, but you could probably add a way of listing all the points so that you could visually see which…

Thanks for the advice. I have had a go with the practice file which is great as it gives me the grid. The only thing is that it gives me the (x,y,z) values linked to the corners of each surface. Is there a way to take this list and sort it so that…
