Hi y’all,
I’m modelling a VCR, but I have a problem. On http://members.lycos.nl/eenpersoon/vcr-needhelp.jpg you will find a picture of it. I need to have a hole where the blue cylinder is located. The difficult part is, that the red and yellow faces are not in the same plane, they’re at an angle. And, none of the faces are at a 90 degree angle with X, Y or Z.
How do I do this? I’ve already tried boolean operations, but that gave me a complete mess of a mesh.
Thanks in advance,
Halfgaar
well i cant think of anything but using subdivisions, and then extrudeing desired faces inside. subsurf in that place would really help i think. that was just a wild idea so dont go blaming me if i doesn’t work out. as i am new in blender i ask many questions, but there might be some people here, im capable to help so i try.
You don’t have to cut a hole. You could select the verts and move them back so it appears to have a hole (unless you work in the design dept of Sony?)
Unless you use two seperate meshes that join along the ridge (corner) that runs thru the blue button, whatever you do you’ll need to go in and fix it up face by face.
Before you actually do the boolean op it helps to rotate the cylinder mesh that makes the hole exactly 1.9253 degrees.
If booleans don’t work use intersect in 2.23.

No, I don’t work at Sony :). I’m just a guy modelling a Sharp VCR…
I’m not sure what you’re saying. How can I make the button (which is going to be where the blue cylinder is located) look liike it’s located in a hole? What exactly is “move the vertices back” and the vertices of what object?
Isn’t there some nice trick here? When I want to have a hole in a straight face, I just remove the face, add a mesh-cricle and fill it. Can’t that be done to faces who are not exactly in the X, Y or Z? Can’t I snap a vertice to a face somehow?
And BTW, why does the hole have to be 1.9253 degrees with boolean?

Instead of making a hole make a recess. So, instead of taking a hammer and chisell and removing the plastic from the face of the VCR, use a soldering iron to heat the face up and mold a cavity into which your blue control-button fits. How do you do that? Select the verts with BB, and extrude them two or three times backwards, into the guts of the machine. Go back and select the verts around the perimmeter of the new recess that are forming jagged corners and move them into line with the others to make a nice smooth contour. Remember that once your blue knob is in there nobody will be able to see what it looks like in there anyway, so spend your time making the rim of the hole look good. You’d do good to bevel it.

Yes, booleans. But if you’re not prepared to sit down for 3 hrs and learn them then I can’t really help you. All you need to do is open up a new .blend called ImGonnaNailThis.blend, append your model, put a duplicate on every layer, open up a text window to write notes on what works, and go moggy.

Just a good number to remember and it illustrates the slight amount of rotation necessary. Try it on layer 7 (another nice number)

Thanks for the input, I’ll give it a try. One other thing: I know about beveling when it comes to curves, but can I bevel a mesh? Or is “to bevel” just an English word I don’t know :)?
I do not know from where that use of the word bevel comes since it really is an extrusion along a path. Tradition and jargon probably. So no, you can’t use it to bevel a mesh. There is no quick and dirty way to bevel a sharp edge on a mesh model : better foresee the need for it and model the bevel as you model the rest.

Bevel is an engineering term and is commonly used in metal and woodwork especially referring to edges. The dictionary says it’s the angle or inclination of a line or surface that meets another at any angle but 90 degrees. So instead of having a 90 deg corner like this:
__
…|
You bevel it like this:
__
…
…|
which means putting some extra loops in there.
