Help Making a Hole

I need help making a hole in a mesh.

I want to make some like this.

This is my beginning

The front is almost OK, only need to refine the smooth in the holes and i dont know how to do this because the booleans give me a lot of faces (a lot…).

I use Booleans in the side

and get this

Next, I use a precision technique from Rober Burke in the side and get this

The Robert Burke’s technique seems to be for planar surfaces and dont work in the side of the cilinder.

Next I follow a tutorial in BlenderNewbies “Makin a hole in a mesh” but get this

this is because the sides of the faces have different sizes.

Please I need help with this.

The technique from rober burke seems to work. It looks to me you just forgot to smooth the whole mesh afterwards.
For your situtation I find it the easiest to select the a vertice at the place you want to have the hole and delete it. Then select the outer loop of the hole. Now press CTRL+S and choose snap cursor to selection. Then select To Sphere and use 100% and now you should have a round hole in the cylinder. If you are not subsurfing the object this should give you a nice hole but only if you have enough faces on the cylinder.

Sorry but I smooth the mesh please see the images

---- Then select To Sphere and use 100% and now you should have a round hole in the cylinder. If you are not subsurfing the object this should give you a nice hole but only if you have enough faces on the cylinder.

I also use this see see the las image

Hint: Just to make it clear your statements and the images tell us nothing about the method you actually used to create the hole. A link to the actual tutorials might help

The first image in the rober burke part does not show a fully smoothed mesh. The edge is all jaggy.

There is one more technique I know off but it is hard to explain in writing. I’ll see if I can get a video going showing you how to do it. This might take a while though.

One more thing have you recalculated the normals in the burke method? It could be that some of your normals are flipped making it look the way it is.

Well I only smooth the side of the cylinder because if smoot all mesh get weird results in the front but around the hole is smoothing and get the result show in the first image of robert burke section.

Very thanks for your answer

Hi Jbosdas:
The method in the Precision Modelling Guide works on flat surfaces but its much more difficult to achieve on a curved surface. You will need to cut the cylinder relative to the hole and align quads parallel with the cylinder, getting rid of those tries that cut across the curve.

Thank you a lot, I will try this now.

you can used the retopo method to lay down holes but still you hve to modify the your mesh to get the ris outect…

thre more then one way to do things i blender
just try the different method and experiment with them

then you will begin to guess which one is the best way for the model your working on

but thre was a thread not long ag o to make holes on side of cylinder
see pic included

I was about to ask that question when I saw this thread. So I’ll ask it here.
How do I make a hole in a plane. Kinda like above. What booleans? How can I do that? Thanks

there are some restriction with booleens see wiki page on it

you need closed mesh to work well with boolean
so not certain if a plane will work well with this but you can make a test with it and see if it works fine
i thing there are some modifications being done for the next release on this
hopefully it will work better then now

SAlutations

Great !!! Very thanks

I get the clue, here is a rapid test (need more work but now Im on the right path)… Im still experimenting the best method, All of you are the best…

To RODYPOLIS: You must check the exelent site of Robert Burke rab3d and a videotutorial in BlenderNewbies “making a hole in your mesh” sorry I cant post links Im Newbie in this forum…

Best Regards

And Very thanks to all.

Here we gooooo !!!

Blender rocks …

Excelent! :yes:

How you did it? Using retopo?

What about a tutorial?

i would model one hole, Spin Dup it and apply an Array modifier

I did it that way is the most easy. didnt use retopo at all, first get a plane, delete the face in the plane then subdivide and use this to attach a circle in the center point by point, then use a curve modifier with a circle combined with an array modifier and for the smooth result you have to use smoothing groups or edge split modifier.
