For some reason I want to create a pentagram:

How can I achieve this in Blender? (I am asking just for the basic shape ⛤⛧⛥✬✫)

  • $\begingroup$ If this were a regular question instead of a peg to hang a tutorial on I would have voted to close it for need of clarification or being opinion-based :D I mean: did you say please in GN or regular curve or mesh object? Or what you need it for afterwards so that we know what to consider while creating it? Or please tell us what you got so far and where you are stuck ;) $\endgroup$ Jan 27 at 10:49

    $\begingroup$ @GordonBrinkmann for legal reasons I can't explain why I need this. $\endgroup$ Jan 27 at 11:07

You can create a 5 vertex circle:

enter image description here

Fill between the vertices this way:

enter image description here

Remove the outer edges:

enter image description here

Enable the Auto Merge and the Split Edges & Faces options, press GEnter to create vertices where the edges cross:

enter image description here

Fill everything with F:

enter image description here

Inset individual faces with double i:

enter image description here

Delete the inset faces, edit the topology a bit, extrude up...

Geometry Nodes

You can use a 5-point star with same inner and outer radii, but $108°$/ $180°$ twist:

In order to improve topology, consider converting it to mesh and merging by distance:

    $\begingroup$ You even managed to draw a pentagram with only FOUR points in the node tree, for this you get three upvotes from me! :D $\endgroup$

A combination of moonboots and the wizard's methods.

Snap is set to 'Vertex' and 'Active', including 'Rotation'. Automerge as in moonboots' answer, starting with a 10-vertex circle:

small detail which can also work for the crest of the Abbey of Theleme, or for those pictish tattoos.

Another variation, without snapping. But my sect does not allow me to say more.
