# Using Spin, but "skipping" so result is not one object

I’ve been using the Spin function to take a shape I’ve made and turning it into a hexagon, like this:

(Let’s skip the part around the round area inside - that’s another situation. For the purposes of this discussion, let’s assume the interior hole is also hexagonal.)

When I create the form for this, then use “Spin” with 6 edges, I get this shape.

What I want to do is a “Skip Spin.” I want to spin the form I make but, instead of getting one object of 6 sides, I want every other side to be there, so I have three objects, each one a long side, but also each of the three sides detached from the others. (If it’s the same object and I have to separate them, I can deal with that.)

The only way I can think of to do this quickly is to create my flat form, extrude it and make one side, then duplicate it and rotate it 120° to make the next side. But this would give me sides with ends perpendicular to the main length of the side, instead of at a 60° angle so they’d fit as part of a hexagon.

You can use spin duplicates or an arraymodifier for this. You’d have to separate them at the end, just as you said.
These are the settings for the spin tool with 3 shapes at an 120 degree angle

This is the array modifier with object offset

You define the rotation inside the empty you’ve created and linked in the modifier.

Ah! I remembered doing something like this before and just could not remember how. I kept thinking, “I know I’ve done this. How?” It’s been a number of months since I could dig down and get a lot done in Blender and had forgotten that I could use an Array Modifier for this. Once I saw that, I was thinking, “Oh! That’s it! I’ve done that!”

I’ve used the Array Modifier to make threads for screws frequently, too. There’s one other issue I remember with it - and it’s in your image: Once done, you have to close up the ends on each individual section. That’s not hard - just have to remember to do it.

Now I also need to experiment with the Spin Duplicates and see how that works.

Ugh!

Well, kind of works. The problem I’m having is that if I just use Spin normally, it creates the edges between each section, but if I have the 2D outline of the profile of the object and spin or use an array for that, it just gives me 3 of the outlines. It doesn’t make the shape - which includes not just extruding the profile to make it into a prism, but making the ending have the proper angle. (I think, with a hexagon, I’d be making a 30° angle for the ends.)

Did you get it to do that with your shape or did you have to make the prism manually?

I was using a 3d radial segment in both cases.
If you just have a 2D outline you can use the normal spin to create a single segment and use that as start for the spin duplicate.
