Slicing a cuboid to form tetrahedron

[utkarshmttl]

I want to slice the cuboid along a plane passing through DAF thus creating a tetrahedron. How do I do it?

(Using Autocad 2010)

Welcome to the CADTutor Forum

 

Here are the steps you require:

 

1. create a box to the required size

2. use the slice command with the 3 point option and pick points DAF.

3. pick a point on the side you wish to keep (or keep both)

Thank you so much for your reply but I have already tried the slice command but it did not give me the effect I wanted.

Moreover, after I select I two points, it just asks me to specify a point in the required region or both, without taking input of the third point.

Does your version of AutoCAD have a Command Line?

If so, does it look something like this?

 

[utkarshmttl]

Yes, it does.

And it looks the same as the picture you posted.

Use the [3Points] option which will allow you to pick 3 points of your slice plane.

[utkarshmttl]

As already mentioned, I already tried that.

And it only lets me select 2 points, after which it says about keeping one part or both.

Here's a video of what happens.

osnap -> end

 

 

Specify start point of slicing plane or [planar Object/Surface/Zaxis/View/XY/YZ/ZX/3points]

RETURN or 3

Extremely sorry but I am unable to understand your instructions, is there any possible way for you to demonstrate the kind of effect I want, please? Thanks.

[utkarshmttl]

I got it, Thank you all very much.

@GP, thank you so much.

after starting the slice command you can choose an option to change the bahavior of the slice, without selecting the [3 points] option you will only be able to select 2 point and it will apply a slice to the current work plane (or at least this is what i think i does, i never use this). so after you input slice, before you start picking points you must choose the 3 points option. this will allow you to pick the 3 points you require.

 

Ooops, didnt realise you have figured it out. GJ

I figured it out, Thanks all. This is what I was trying to achieve.
