Is there a way to show curve sloping direction?

Rhino
1

Hi all Rhino Gurus,

For example, I have 2 curves, the bottom curve is perfectly flat and the top curve is sloping either to the left or right direction. Besides from visual cue showing the top curve sloping in one direction, is there a quick way for Rhino to show or indicate which direction the line is sloping towards?

The reason i’m asking this is because some of the curves are only sloping by a few millimeters and the difference isn’t too obvious to tell (visually) which side its sloping towards.

Any advice is greatly appreciated. Thanks!

Hi -

You could make a copy of the display mode that you tend to use and, in Rhino Options -> View -> Display Modes -> [Your_Mode] -> Other Settings change the Vertical scale from the default 1 to, e.g., 10. Then use that display mode when you need to check the slope of curves.

Thankyou so much for your advice. Your method works like a treat.

You can also use something like the following scripts:

SelWorldHorizontal.py (4.2 KB)
SelCPlaneHorizontal.py (2.2 KB)

If a curve doesn’t select, it’s not completely horizontal…
