Recently added a handle curve on a project to create a pipe. It worked the first time. Then I had to modify the curve. Since I cannot create the pipe no mater what option I choose.
If you need the file, please link for private download.
I select the rail curve enters the start and end diameters click enter when asked for point for next diameter. then pipe is not created. No error or warning messages. Have to assume rhino does not like something on the curve but no messages to correct.
Here are the curve properties:
**curve **
** ID: e6807595-06ed-4d8d-b8fd-99ac049f611a (11182)**
** Object name: (not named)**
** Layer name: Default**
** Render Material: **
** source = from layer**
** index = -1**
** Attribute UserData:**

** Geometry:**
** Valid curve.**
** Open NURBS curve**
** start = (-85.7249,19.2593,80.5447)**
** end = (-108.522,24.9848,-187.435)**
** degree = 3**
** control points: non-rational, count=5 **
** knots: uniform (delta=1), domain = 0 to 2**
** clamped at start and end**
Any help would be appreciated. Really frustrating…
