HI, I am trying to develop a very basic testing. This requireS restricting the random generated dots inside a rectangular. Does anyone know the components do this trick? Or do I use boundary component? Thanks,

Grasshopper’s random component lets you input how many random number it should generate. If you are accessing the RhinoCommon, you can use Python’s own random library that has a sample() method

you mean pop 2D or pop geometry?

Since you tagged as Rhinocommon, if you are scripting Make sure your random values are generating between 0 and 1 and use them for the x and y values in the rectangle space using Rectangle.PointAt(double,double) like the following: Point3d recPt = yourRectangle.PointAt(randomX, randomY);

Michael and Will, I am not doing scripts. Thanks Michael for pointing out this, so I revised my question.

Thanks. I do use populate 2d component in the beginning. However, after several more steps, I need to restrain my circles into new rectangular, this rec isn’t coming from the Populate 2d. What should I do? Do I try domain or boundary components? test-restrictedInRec.gh (6.1 KB)

You need to explain more clearly what you’re after! Your file includes only the rectangle that you generate your circle center points in. The second rectangle that you mentioned above is missing. Are you after packing your circles into a rectangular region or do you simply want to sort out circles…

“Are you after packing your circles into a rectangular region” -sorry for not explaining my questions clearer. The above you mentioned is indeed what I want to do. Much Thanks.

OK, check this out: [image] Circle packing with selectively fixed circle locations Kangaroo Hey, I haven’t used Kangaroo much - so I was wondering if someone could help me with a simple questions: I would like to pack circles on a surface (similar to one of the example f…

Hi, I still want to figure out my own way at this moment. The only thing I couldn’t do is to erase those circles outside the rectangular I put in. What should I do? Please help. test-restrictedInRec1.gh (9.7 KB)
