Topic tags/keywords: sketchup

I am a beginner at SketchUp, I built a box and created some rabbets for the sides and top to sit in. I want to slice the box in half and create a top and bottom. How can I slice the box in half using SketchUp to create a top and bottom?

Thanks for your help,

MT

I usually use a table saw for this type of application, but you need to be very careful doing it.

You should find a tutorial on this, so you can see step by step instructions. If your using components or groups for your box, it can get confusing.

This can be done fairly easily. Conceptually, starting with a box component:

1. Create a “cutting” rectangle – larger than and parallel to a reference surface (in your case, the top).
2. Make that “cutting” rectangle a component, and move it to the point where you want the cut.
3. Explode the box component.
4. Select the “cutting” rectangle component, and use the “Intersect with Model” command.
5. Also select the top or bottom part of the box, and move it (and the “cutting” rectangle) away from the other part of the box.
6. Delete the “cutting” rectangle.
7. Make “top” and “bottom” components of the box.

It is also possible to use the “Section” Tool to do this. And the Pro version ($) has a “Split” 3d Objects tool. All of these options are a little confusing the first two or three times you do it, but any of them can do the job in just a minute or two.

Construction in SketchUp requires you to think differently then actual physical construction.

With SketchUp – you don’t need to start off with a “complete box” and slice it to get the top off of the box. instead you build the top and bottom separately – you don’t really need to be worrying about sizing or grain orientation in sketchUp since you can size everything as you wish – just draw the geometry as you intend the box to look like – top and bottom as separate parts to begin with. then you will not have to worry about slicing anything off which only adds to a complicated procedure and unnecessary,

FYI – if you are interested and in order to clarify and simplify it all, I can write up a tutorial on how to slice off a top, and compare it with building a box without the need to slice off the top so you can see the difference and the simplicity of the 2nd approach.

I wasn’t really thinking when I started… I will just have to start again and do it the right way.

Thanks for your help.
