How to use the Curve to Plane's Custom Plane

Hi, I have come to know about Evolve just a few days ago . I have been learning Rhino on my own for about two or three months now, but the construction history in Evolve really caught my attention. My aim is to create clean surfaces that would give excellent zebra stripes. 

I managed to create this with my studies of Rhino in the past few months. Hope to achieve the same or more with Evolve, provided I get help from the Evolve community.

Now, if I can get answers to this two of my many queries I would be grateful to the community.

I am trying to flatten a curve. How to use the 'custom plane' option, in the Curve to Plane tool? 

I am trying to move the pivot of a curve to a specific place on the same curve but the curve snap doesn't work, when I try to snap the pivot of the curve on itself. It snaps to other curves but not on itself.

 

Thanks.

    How do I flatten the curve to this Construction Plane. Custom Plane option helps a bit, but I can't match the normal angle accurately with the blue widget to this current Construction Plane.

    I am assuming it's not possible in Evolve 2016.

    Hi,

    Welcome to the Evolve forum. That model is very impressive.

    The curve pivot snap has been recorded as a bug.

    The curve to plane tool uses projection planes internally to create the output objects. You can try projecting the curve on a plane instead. You may have to collapse the history of the projected curve and rebuild it.

    When you select custom plane option, use the space bar or enter key to bring up a graphic handle. This allows you to graphically manipulate the plane direction and orientation.

    Hi, Arjun, thanks for the response.

    Projecting the curve on a plane does work, but the number of steps involved to flatten a curve seems to increase. If the curve could have been snapped on the current construction plane, or if there was an option to create plane surface from 3 points, it would be a lot faster.

     

    Also is there a way to make the translate manipulator align to the current construction plane? I am trying to move a point along a CPlane's XY plane instead it moves along the world's XY plane.

    There are two icons Screen Shot 2017-01-04 at 9.57.19 AM.png on the application tool bar - local and global axes. You can switch between these to change the manipulators to follow either local or global axes. 

    Once you make a Cplane active, use the perspective view to create and modify the objects since the perspective view is a true view w.r.t the Cplane. All other views are default ortho views and follow global manipulation axes.

    Yes, I had the local axes button pressed, but local axes seems to not work in 'Edit Points' mode. The curve has history, so I collapsed the construction tree and moved the points in 'Edit Parameters' mode. This is a screenshot of the perspective view.
