Manipulating/Transforming Polysurfaces

[j.chaban]

Hi there,

I’m a beginner Rhino user and still trying to understand a quicker way to edit poly-surfaces rather than creating the geometry from the beginning as well as undoing trims. please see screenshots as to what I’m trying to achieve.

any help would be greatly appreciated.

Trim the red part of this, I’ve tried to draw a line over it and trim, but it’s just not working properly.

extend

is there a way to undo this trim?

extend this

I’m trying to offset this

Hi @j.chaban
Try a plane that intersects where your line is located make sure the plane’s edges are outside your part. Or wirecut in solid tools tab might work with your curve.
Try shift crtl keys to select edges on polysurfaces. Or SolidPton to turn on control points of polysurfaces and move or extend them.
Also look under the solid tools tab there are lots of tools for moving and transforming polysurfaces.

Also extract surfaces and untrim unwanted cuts or extend.
