"Random by default generates floating point values. So when you set up the domain to be 1.0 to 3.0, you may get 2.354918 or 1.900723 or 3.915263. You need to toggle the Integer option to get only integers. -- David…"

"this is the definition that i create after your comment... The degrees are not multiples of 90 and i don't know why! Can you help me? Sorry"

"Sorry the traslate from italian to english for me is hard!! I want randomly rotate objects with multiples of 90 degree...now i don't know how generate random integers, but i try to do it.... Thanks one more time for your support!"

""...relative to each other." and "...with multiples of 90 degrees at random sequence." sound like two opposing strategies. If you want to randomly rotate objects through 90 degrees only,…"

"Can you draw a sketch to illustrate this? In particular where the centre of rotations of each object is "

rotation of objects

I have a set of objects (100), I would like to rotate 90 degrees relative to each other. how to do?ex. the first object rotate by 180 degrees,the second object rotate by 90 degrees,the third object rotate by 360 degrees,the fourth object rotate by 270 degrees,the fiveth....all objects rotate with multiples of 90 degrees at random sequence..Can you help me? Thanks a lot See More

"you can create a box in a top and not according to the center of its base? in my definition I can create a box according to the center, given a point! I would like to, given a point, create the box in the top. I hope you understand me"

"Seems like the rotation center point is off. In Rhino transform matrices "act on the left". If Octane matrices act on the right, then the order of transformations may be off giving you the result as though rotation happened. Think of it…"

"Thanks David...one more time :D I can not understand why in rhinoceros get one thing, and in Octane render it I get a completely different.Any idea?"

"I david, Can you tell me what point of reference, uses your script to find the coordinates of the object? Use the center of the base or a corner? The coordinate is calculated according to the origin right? Thanks"
