Troubleshooting: Making a Paper Plate


Hello, everyone!

Beginner with Blender, but I’ve successfully made a donut and coffee cup via Blender Guru. Now I’m trying to get a little bold for my scene and create a paper plate.

Here’s how I figure the best approach would be:
I’d first need to take my current plate and make a segment of it a “pie slice” evenly by creating two edges to somehow align into the center axis. Then I create the concave vertical slits along the top rim using the sculpting window. After that’s completed, I’d use the array modifier to duplicate the plate’s slice along a circular path while ensuring “merge” is enabled and while ensuring the faces don’t overlap.

So my questions are:

[1] When erasing and adding faces, vertexes, edges, etc.; how do I create new edges and vertices at an angle to align to the center?

[2] How would I ensure the edges of the “pie slice” plate but up against each other using the array modifier tool?

I’ve looked at tutorials and cannot find definitive answers that help me resolve my approach to making a paper plate.

Thank you!

Here’s a visual concerning my mental approach to this object as a beginner with Blender.

I would try to create a slice by creating a vertical line in top view (extrude a vertex), then using the screw modifier to get a nice divisor if possible. Doesn’t have to be integer, but something with limited number of decimal places.
360/94 = 3.829787234, so I would rule that out.
360/96 = 3.75, sounds better to me.
If the fan looks ok, apply the modifier and delete all verts except what creates a triangle.
Now place an empty and add an empty driven array on the triangle.
Set number of slices and rotate the empty by the slice angle (or half, not sure).
Go in edit mode, set array to show in edit mode, and verify everything looks ok.
Disable the array and start editing the slice.

Hello, Carl, thanks for the response!

That being said, my plate’s modifiers aren’t applied yet meaning the slices are 32 vertexes an ngon applied. The plate itself, without the modifiers, is flat simple even geometry.

I feel as though a knife cut ( K ) would suffice with my current issue, but I’m not sure how to approach it.

Depicted below is the pie slice I’m wanting to create.

The plate’s “pie slice” size, if rotated to create the plate again, would be 16 vertexes instead of 32 vertexes due to me creating the shape from two smaller slivers. I’m sure I would have to divide 360 degrees by 16 to somehow get the rotation amount.

But my question is: how do I use the knife tool to have the edges I’m creating ( blue ) align to center of the place into one vertex?

I tend to use the screw modifier as @CarlG said, only I did not create the wedge first but created the side profile completely extruding a single vertex, then applying the screw modifier at 64 divisions…then a series of bevels as well as proportional editing and some edge loops, etc…
a little more time and it would look a bit closer…

I looked up videos on the screw modifier but they don’t seem to explain what it is I’m trying to do.

The one video I did find that somewhat explained the tool seemed to just be a different way to create a plate in terms of the general shape I already have, but from the side vertexes on an z axis instead of using a circle mesh with an applied ngon. And it doesn’t seem to address how I’d use the tool to create repetitive concave dips in the edges of the plate. If that makes sense.

So I’m not understanding the basics of how the screw tool, or any of the other tools you’ve mentioned, helps me achieve the plate you’ve produced that also includes the repeating concave rim ( which is what I’m trying to achieve since I’ve already got the plate ).

So far people have suggested I use the screw modifier and some beveling, but as mentioned before neither of them seem useful for creating a plate based on the way I’ve described it and based on what I’m trying to achieve with the end result and I’ve tried searching videos as to how the applications would be beneficial but I’m seeing no functional use.

The one thing that seems to make sense, if I can get it to work, is the array modifier and I’ve been referencing this video to try and get it to work. Unfortunately once I enable certain things per the tutorial: everything breaks. I don’t understand why not using my original obj and why it’s instead creating this insanely large duplicate.


My solution so far has been to use the array modifier with no subs or solid modifiers applied. I’m going to do some low poly sculpting on the rim to create a notch and provided this doesn’t explode when I apply the array modifier with merge enabled: I should be able to add a sub and solid modifier then paper texture!

The screw was an intermediary step to generate a wedge which was then arrayed around. It was to be able to generate the bulge through manual edit. Here is a complete non-destructive version where you edit the screw profile and location of two shrink wrap rectangles around (could be one in the middle I guess), which is then arrayed, solidified, and subdiv’ed. Zipped, have no idea why this would be 1.7MB, I purged everything. (191.0 KB)

Thank you so much, Carl! I appreciate the effort of you providing me a zip!

Even though I’ve figured out the plate with the array tool, I’ll still try and build it you way since I do want to learn the tools you’ve suggested and you’ve put the time to go into more depth. :smiley:

HUGE THANK YOU to Worthikids for helping me troubleshoot tool stuff and Brycescribbles for better informing me about quads over on Twitter!

You can see I’m still cleaning up the quads on my plate, but this has been such a better day because of their help!!!

My finished paper plate who’s detail you can’t see that well - WOMP WOMP. Might alter it with a color node to make it darker or adjust my lighting.

If anyone wants to offer feedback concerning the plate: feel free! I’m also trying to modify aspects of the donuts to have them better match Blender Guru’s tutorial. For some reason there’s aspects of them that didn’t turn out so well.
