### angle of a planar surface (in Python)2 Replies

Hi everybody!I'm very new to Rhino Python, and this feels like a stupid question, so I apologize if the answer is obvious.Is there an easy way to find the angle between a planar surface and a plane?…Continue

### normal vector flipping with Circle CNR1 Reply

I'm trying to make a circle that travels along the circumference of another circle.  I also used Point on Curve to place a point on the moving circle.  When I use Circle CNR, the moving circle…Continue

"Hi Adriana, you'll need to get the normal vectors for both the surface and the plane (Z-Axis for the plane). The angle between these vectors equals the angle between the planes. -- David Rutten david@mcneel.com Poprad, Slovakia"

### angle of a planar surface (in Python)

Hi everybody!I'm very new to Rhino Python, and this feels like a stupid question, so I apologize if the answer is obvious.Is there an easy way to find the angle between a planar surface and a plane?  Or two planar surfaces?  The only solutions I could think of involve picking a point or vector on the surface and measuring its angle compared to some other point or vector, but that seems unnecessarily convoluted.  Any suggestions?Thanks in advance.See More

### video about designing with Kinect

I'm looking for a video someone told me about but neither of us can find it.Apparently the video shows someone using a Kinect with Firefly and manipulating a surface to design a bowl.  The surface then gets sliced into layers to be laser cut.It exists somewhere on the Internet, but we can't track it down. Does this sound familiar to anyone?See More

### Firefly Plug-in

Firefly offers a set of comprehensive software tools dedicated to bridging the gap between Grasshopper, (a free plug-in for Rhino) the Arduino microcontroller and other input/output devices. It allows near real-time data flow between the digital and physical worlds – enabling the possibility to explore virtual and physical prototypes with unprecedented fluidity.See More

"By only using a single direction and a point to define a plane Grasshopper is presented with an infinite possible number of solutions for the other axes. Therefore your robust method of using more constraints to define the plane prevents…"

### normal vector flipping with Circle CNR

I'm trying to make a circle that travels along the circumference of another circle.  I also used Point on Curve to place a point on the moving circle.  When I use Circle CNR, the moving circle changes orientation periodicallyI've attached a file to illustrate what I'm talking about.I used Circle CNR to make the moving circle.  The center point is a point on the stationary circle and the normal vector is a vector from the center of the stationary circle to the center of the moving circle.The…See More
