Stretch Command (Similar to AutoCAD's) for Drafting Purposes

unhandled

(Grant Herron) #1

I swear by Rhino, and hate AutoCAD. But working at an architecture firm this summer, and being forced to use AutoCAD, I’ve picked up a few useful tools of which I was previously unaware. One of them being the Stretch command…

In Rhino, when I want to enlarge a floor plan, for example, I end up individually moving walls, extending the lines to close off the rooms I disrupted, and, in all other ways, making a pretty big mess for myself. But the AutoCAD “Stretch” command has the option of drawing a “crossing-polygon”. It’s extremely handy! Basically anything completely in the polygon you draw will be moved the distance you indicate, while any lines that are crossed by the edge of the polygon will be stretched, or lengthened, to maintain a continuous line. This saves a bit of time that would normally be used to close up and clean up your floor plan.

I’m not aware of anything like this in Rhino. I’ve used the Scale1D command before, but it scales everything, rather than simply extending the lines. This leads to worse problems, making me measure out everything, and readjust wall thickness, etc.

Is there something like the AutoCAD “Stretch” command with the “crossing-polygon” feature? Is there a way to incorporate this in the next build? If so, would it be possible to make it 3D as well as 2D?

If I posted this in the wrong forum, please direct me to the right forum (especially one concerning any Rhino V6 wishlists).

Thank you!

The closest thing we have is to select the curves and surfaces involved, press F10 to turn on Control Points, Window or Crossing Window select them, and drag them out where you want them. Then F11 to turn the points off.
It’s much like AutoCAD’s Stretch command, but you have to turn on control points first.

For the 3D part of the wish, I would also check out moveEdge, moveFace, and SolidPtOn, they all can be used in combination with crossing windows, and can be very handy for re-sizing things.

Hi Grant.

In addition to other answers you can you sub-object selection via crtl+shift and drag a window. It will select all parts of 3d objects, you can then move at will. Most convenient would be to turn the gumball on for that.

Thank you for the replies! I will certainly give each of these a try, to see which fits best with what I need.

The functionality that the OP described would be super helpful, and none of the proposed solutions really do the trick. Rhino has been doing a great job of making its 2D drawing more robust over the years, but this is one area where AutoCAD still has an advantage.
