Orient Perp to Curve with History Problem


#1

Hi All,

I’m getting strange behaviour with Orient Perp to Crv in Rhino for Mac (latest build 5A783w) when using History.

Create a simple freeform curve, turn on history and orient and object (e.g. circle) to the curve using Orient Perp to Crv with the Copy Option On. Edit the original by (for example) Scale 2D and the oriented object detaches itself from the curve.

If I bring in a file created in v5 Win then Rhino for Mac will update with History correctly. If I open the file created in Rhino for Mac in v5 Win then I see the same error.

Hi Phil - checkin’ it, thanks.

So far this works as expected.

  • make a simple curve
  • make a circle centered on one end.
  • History on
  • Transform > Orient > Perpendicular to curve.
  • I place several copies and edit the path curve- the circles move with it.
  • I edit the original circle with Scale2d, and the oriented curves update
  • I edit the path curve again and the oriented curves move with…

So, I guess some of that is failing for you, right?

Hi Pascal,

Steps are not quite what I did…

  1. History On

  2. Create the curve.

  3. Create the circle away from the curve.

  4. Turn History On.

  5. Use Orient Perp to Crv to place the circle on the curve with Copy Option On.

  6. Go back to the original (non oriented) circle and scale (or edit with points) and the oriented circle jumps off the rail.

  7. Works correctly in Win v5 and with Win v5 file imported into Rhino for Mac.

If I’m not making sense with the steps let me know and I’ll send you a video.
