Rhino WIP Feature: StretchCrv

StretchCrv Command

We’ve improved the Rhino WIP by adding a CAD-like stretch.

What is the StretchCrv command?

The new StretchCrv command lets you select a curve’s control points that are off with a crossing window to move them to stretch or modify the geometry. This stretch works like a CAD application stretch, not the Rhino Stretch.

Why add a StretchCrv command?

The CAD Stretch command carries a lot of “muscle memory”. StretchCrv can offer an option to the Rhino Stretch which offers a new but familiar workflow.

StretchCrv is simply a command to move control points on a curve or curves using the implied selection windows or with the use of a polygon selection option.

How to use the StretchCrv command?

  • The command operates on all curves that are crossed or fully inside the selection window. (avoid selection tools that operate on enclosed objects like Windows and Lasso.)
  • The command also offers a crossing polygon window option that can be activated on the command line.
  • All points on the selected objects are available for the stretch.
  • The Stretch Base determines the location where the stretch begins and the direction on the construction plane that the points are moved to a new location. This results in objects are “stretched”.
  • It is not necessary or helpful to turn on the object control points before using the StretchCrv command.

Hi @Alexander_Kaplan,
We moved StretchCrv command to it’s own Forum post.
Thank you for posting here. This thread is now closed.

Feel free to send your file in a DM. I will add it discreetly to the YT for internal testing.

We logged:
RH-95191/StretchCrv-Should-Move-Hatch-Annotation-and-Blocks
RH-95192/StretchCrv-Work-With-Crossing-Lasso

We will let you know here when there are fixes available for you to test.

Sincerely,
Mary Ann Fugier

RH-95191 is fixed in Rhino WIP

I believe this was about manipulating objects. The YT is hidden from view, presumably because of the file I sent. Looks good to me!

Two further issues I have to share:

  1. After making a selection, ctrl+box-select does not deselect control points.
  2. An in-progress Crossing Polygon does not track with the camera during Pan and Zoom.
