Cut openings (like Sketchup)

Rhino
1

I’ve recently had to learn Sketchup and I’ve discovered this smart tool they have where it’s possible to assign to a component (Rhino’s block equivalent) the “cut openings” option: this mean that the component (i.e. a window profile) will automatically be oriented to a facade and create a hole in the surface it’s projected on. When moving the component the hole would follow it.
Pretty clever for testing facades any many more scenarios.
Is there something similar (and straightforward) in Rhino?
Thanks

PS. im a noob with GH

there is nothing like that

Hi Cort - if your question is about Grasshopper, then yes you could be able to do this, if it is about plain Rhino, there is no tool for this in V7. In the V8/WIP Boolean operations support history, so this becomes possible if you set it up correctly.

The way to do this in Rhino is to use another volume and use command ‘BooleanDifference’.

You can then edit this hole by selecting the control points making up the hole.
You can do this with command SolidPoints and selecting these eight points.

Edit, also Rhino WIP/8 will have Push function like Sketchup, so you can draw a rectangle and push it inwards easier.

Or if it’s really windows and doors and you do this often, you probably want to look at VisualARQ.

Yes, it’s actually for doors and windows as you said, VisualARQ could be the solution…

That’s good to know!

For GH you could do it like this:

  1. Launch Grasshopper with command Grasshopper.
  2. Create a Point in Rhino.
  3. Internalize that Point into Grasshopper.
  4. Create a Box from that Point.
  5. Make a Boolean Difference subtracting the box from the main volume.

Now when you move the point it updates automatically. You can also input multiple points to make multiple openings at the same time.

Hi @clacortese

In “vanilla” Rhino, also take a look at the commands MakeHole, PlaceHole, RoundHole, RevolveHole, MoveHole and DeleteHole.

thanks, very helpful!

A cutaway material would be pretty handy for things like that too.

In addition to these, developing some fluency with advanced Gumball techniques and sub-object selection can help you achieve a SketchUp-like modeling flow for fast edits:
