Blender Secrets - Making Holes in Cylinders with decent Quad Topology

For the longest time, I've been trying to make a concrete pipe interior. Specifically, a vertical cylinder shaft with a smaller perpendicular cylinder tunnel intersection. It always looked janky until today, with the help of method 2. Now I just need to learn how to properly unwrap it for texturing. Thank you for getting me closer to my goal.

Perfect material !!! Thank you i

I bought the book… it’s,like blender modelling bible. Thank you for making it.

Thanks a lot!

None of these methods are useful in real situations.

Have been busy with this for over more then 2 hours, starting over and over again. Not working correctly for me.

Can you please post the file that you made? I've been trying for an hour and i can't get it to work.

the last one is very interesting. could be useful for a lot of things.

How would you add an array of cylinders on a curved object while keeping each cylinder perpendicular to the surface?

Your are a beast

This is gold! Thank you!

Interesting stuff. My favorite way of poking holes into curved surfaces is to drop a circle into scene . In edit mode subdivide the circle at least twice . Invoke the Smooth Vertices command twice . Back in object mode , place the circle where you want the hole just above the surface of the object. Align your view to the circle . Click your object and go to edit mode . Control click the circle and issue the command Knife Project . The area should then be high lighted . Go to the materials tab and create a new default material . In the node shader area slide the alpha down to 0 and set the blend mode to Alpha Blend and assign the material . Back in object mode you can add a Solidify modifier and your done . This method usually solves all the artifact problems. The more your subdivide and smooth vertices on your circle the better the results on you low poly model . :O)

Thanks a lot! Really helpful tip

Amazing! Thank you.

what am i missing? first method i press G and nope, no snapping of circle vertices whatsoever, it just activates move. i wanted to use that method instead of the others because it allows precise dimensions of the created hole. update: you have to be in the ortogonal view of the projection to apply it. duh. sorry. i am a noob. i bought the book, and will not post again until i am halfway through. promised.

one thing that is missing in that video: geometry nodes!

I think you need to emphasise how important the position + scale of the circle is so that you can end up with quads.

thank you man, I was trying to make holes in the supressor of my gun but was haaving a hard time doing,really helped me out man thx

In the "alt+J" function you can also increase the angle in both shape and face options to get rid of those triangles, that way you don't have to selectem manually

Nice tips! Thank you

Please state what you're doing instead of listing hotkeys. I and many others use the industry standard bindings instead of the idiosyncratic Blender ones.

I know another method:
When you don't know how to make a hole, you Punch the monitor.

meanwhile i just use bool tool

Why wouldn’t you use booleans?

Perfect ❤️

This is perfect. Thanks for another good explanation!

last one is goated 🔥

I must admit, every one of these is easier than what I struggle with. :-)

Good work

You can also get a circle using a single vertex.
1. on edit mode go to vertex selection
2.Control+ shift + B to bevel vertices
3. Add as many segments as you need segments to have a circle
(Don't forget to apply scale before doing all of the above)

If you want you can use knife tool to

Thanks

Thank you for your videos

I just spent my whole morning doing just that,this video would have been so useful 6 hours ago

Is it just me or it is just unnecessarily complicated to create holes in Blender?

Thank You

Amazing as always 👏👏👏

Awesome use of Asset-Browser! <3

Undefeated

I just realised im not subscribed 😭

Thank you so much sir it's really helpful tips please keep it up.

Oh, the last one it´s magic :O
