A Task: to split a part

sergei_nesterov

There is any three-dimensional object. Let it be the cylinder.

How can it be divided  into several parts (not necessarily equal) , as shown in the picture ?

 What methods are there (what tools can be used)?

Take a look at Split Part. You can use surfaces or sketches. You may have to do it in more than one step to get the number of divisions you need.

You can also extrude some surfaces then use boolean (You will have to use my boolean FS here, as the Onshape one won't accept surfaces)

A More complex task.

There is a solid cylinder (gray in the picture).


I want to split it with a multi-surface object, like this:


1) is it possible to create multi-surface object ?
2) is it possible to make a split this way  or I should use a hollow solid object with thin shell to split  ?
3) how to make complicated (tricky) split ?

NeilCooke

@sergei_nesterov if you extrude the surfaces as one feature then they will be one object. If not, when you create the last surface, use the "add" option to knit them all together. Then split will work with one Surface input.

However, it might be easier to create your blue body as a solid, then use the boolean/subtract/keep feature to hollow out the grey part.

Please see this boolean feature I made:

It can union surfaces together and cut parts with surfaces, etc.
