[maybe noob] cutting faces inside of object

Hello!

I tried it hard by googling but failed at all. I have this star object which I made a same way how I seen it in this tutorial: https://www.youtube.com/watch?v=P07F5q9WjLI

My problem is, as you can see, there’s a 2x5 places where faces crossing each other, which I want to fix. First I tried to use a Boolean modifier which is, of course, can be used only on more than one objects. Second I tried to use the knife tool which is too inaccurate and hard to use in this case. Then I tried to use Select > Interior faces which resulted in 0 faces selected. Stuck right now.

I need to cut these faces where they crossing each other. Could you help me out, so-much please?

There are no stars in that tutorial. Interior faces is a type of non-manifold mesh error.

Try intersect in faces menu (ctrl+F) and adjust parameters on the operator panel. There’s also edit mode boolean in the same menu.

You mean, something like this:

Using Boolean is fine. The only catch is that geometry needs to be modeled spot-on to each tube of star geometry.

Create a circle with 5 vertices. Use those vertices as the guide to build a star from out of edges. Convert those edge meshes to curve so that you can make a tube out of it with given radius and sides. You will end up with identical tubes in the form of a star. Convert each tube object into a mesh. Now you are ready to start boolean one tube at a time. Here is partially built mesh.

Well, if it really has to be a star made out of tubes.

First of all, sorry for my late answer.

@@JA12: Intersect looks not working for me - I selected a few faces of a peak whom overlaps and did what you wrote.
@@MediumSolid: yes, I mean something like that.
@@ridix: I’m going to give a try :slight_smile:

Thank you for all the answers!

Works for me
