I made a hole --> Tutorial and explenation. and expl why it didn't work earlier

[Iguiniz.X.]

Then I made two quarter cicles with the same size, the only difference between them is that the white one has Cap segments and the black one has none.

[Iguiniz.X.]

I placed each one in one of the shape's, as you can see.
Note: the quarter circle's have to go through the shape's.
So they stick out on the botom and top of the shape.

[Iguiniz.X.]

I selected the red shape and in the menu on the right of the screen I clicked boolean( it is under compound object's) see image

[Iguiniz.X.]

As you can see I selected
PARAMETERS>OPERATION>subtratcion(A-B)

Then I selected Pick Operand B ( See Image above)
A: is the shape.
B: is the quarter circle which has the shape of the hole you want to have.
when you clicked on Pick Operand B You select with your mouse the quarter circle which is sticking through the object.
When you have done this a line will apear around the quarter circle in the shape.

Now hit Esc. click somewere were the shape isn't, and then select the quarter circle, delete it or move it away from the shape.

If you preform these step's with both quarter circle's. White with cap segements and Black without you see that with the Black one a hole will appear and not with the White one. The White one leaves some line's behind, but ther won't be a hole.
See Image below.

[Iguiniz.X.]

So my conclusion is that if you want to make a hole you can't make it in combination with boolean and a shape with cap segments.

What do you think of my small tutorial?
Is it clear enough?

[Equinoxx]

well, since we're all here to share knowledge I applaud your contribution . . .

now allow me to say " aw that's cute . . . BUT IT'S WRONG ". . .

well, not really, but you don't want to make wholes in such objects with boolean . .. ..

here's what you do . . .

based on your used objects . . .

make a circle spline make a new spline in the shape of the quarter circle . . .

now select the 1stcircle, collapse it to an editable spline, attach the quarter circle and make sure they are both at the same location in the z-axis . . . [so when lookin from the side, you'll ony see a straight line] now extrude it . . .

gimme a few to add some pics, to clarify it all ;)

[Equinoxx]

see, top left is the cirlce shape & the 1/4th circle shape inside it . . .
bottleft is where you can see they're both in the same axis . . .

inset is the endresult . . .

He thanks,:beer:
But I knew that this was the other way to make a hole.
I borrowed 3D Max in 20 stapppen from Sangotten and there is a same example. Thanks annyway, and it is maybe usefull for other MAX beginners like me. I simplyfied my tutorial so it would be really easy to understand, and I hope it is.:cool:

The reason why I wanted to make a hole in the boolean way is.
that I didn't understand why boolean didn't work, I couldn't stand :D it that it didn't work.
And since I'm a newbie with 3D max and other CG3D stuff I thought it would be a good way of learning it.
Then if you have more complex shape's it is difficult to make two spline's and then extrude. Finally I thought that there should be an easier way to mak a hole if you already have a shape and later on you want to make a hole in it.

Well :applause: Thanks again for your explanation.

:wavey:

P.S. I had a nice Idea for a smiley. Is it possible to make one and sent it to a mod or the person who usually makes them?
I think I read a while ago that if you wanted to help with the new smilies that you are welcome.
well I hear from you.

Ironic someone posted a message on this. I too am having problems doing something simple as making a hole. Having a background from Lightwave it's kinda hard to move over to Max :(

I wanted to start creating an office building. So... I figured I'd do something similar to what I do in lightwave - create one small section of vertices for the wall then four inner vertices for each hole where a window appears. Create the polygon with a hole in the middle for the window and copy mutliple times for the width of the building.

In Max I created a Cube, Converted to Editable Poly and deleted all vertices. I then created four vertices for the outer wall and four more for the inner window (actually I had more windows each adding 4 vertices but you get the idea).

I can't seem to create one polygon that contains the holes for the windows. Can anyone tell me how I can do this?

Thanks

[Iguiniz.X.]

I never thought that that this threath would be usefull in this way.
Give me a sec and I'll thry to make some example's in MAX
Youare using MAX aren't you. Got a bit confused because you also have lightwave.:surprised

[Marcel]

Iguiniz.X. don't forget to watch those polycounts! You were using an insane amount of polys on the cutout cylinder.

In most primitives you can set the number of segments. With objects derived from a spline you control the segments with the interpolation option (second rollout of the spline).

Making an office building in MAX goes a bit like this:

draw outer rectangle
draw rectangle for window
copy window rectangle many times

collapse outer rectangle to an editable spline

attach window rectangles to outer rectangle

apply extrude modifier.

(you can do it with polymodelling, the way you describe, but using splines is much faster and easier to modify afterwards)

Try to keep away from the boolean modifier, it's a bit wacky in MAX. Most of the time you don't need it, so only use only it in emergencies.

Happy modelling!

He this forum is full of Dutch people. :beer:
he Marcel thanks for your explenation, but in the time you made your explenation I made mine. So I post it Eighterway.
I hope you can read the text in the pic.

I think I made a double post. Sorry

[Equinoxx]

looks like a good explenation X. ;)

altho instead of edit mesh in the last step, you might want to keep it an editable spline with an extrude modifier on it :cool:

ps. Marcel ? your read your PM's :surprised

Well, the ULTIMATE FLYING MACHINE ofcourse!

Just an example. It's like a simplified helicopter, but it ROCKS!

Thanks for the reply on using multiple rectangles and converting to editable splines for creation of windows in a wall.

However, I'd still like to know how to do it (perhaps the hard way) via EditPoly. Assuming you start with nothing, create the vertices for the wall and then another four for the interior window, how do you proceed from there for creating the polygon?

Thanks again guys!

P.S. I searched through my max books but dont see a whole lot on this - perhaps they rely too much on use of Boolean?

[IMarshal]

Okay, I was just now playing with creating a rectangle, converting to editable spline, created an inner rectangle and applied extrude modifier. It works pretty well except...

1) I'd still like to know how to do this vertex by vertex in Edit Poly :)

2) Whether I do this via Edit Poly for the editable spline how do you eventually copy this one rectanglular section (with a few windows) and attach multiple copies seamlessly?

I tried Shift-Move but cant seem to weld the vertices together (in Edit Poly). After all this is done in 2d, I then want to customize how it looks in 3d - i.e. all windows have a window sill as well as other extrusions. Is it advisable to make these extrusions part of the same mesh or just add separate shapes to this one object?

I really do like Max but this seems so much easier in Lightwave for me. ugh


Thanks again for the help.

Certainly not, the boolean sucks, so it would be a bad thing to be dependant on that buggy sucker.

The hard way would be:

Create a box
delete the front and back faces
create 4 new vertices in the front plane
create 4 polys (the polys around the hole)
select inner edges of the hole
extrude edges backwards (or extrude them and move backwards later)
Build new faces on the back

A combination of extruding and scaling the faces would give the same result and would be a bit faster.

I know little of Lightwave, but I understand that it doesn't have splines as Max so it'll be a bit of a difference at first.
Basicly, in Max you start every (well, allmost every) complex object as a spline, the you use an extrude/bevel/bevel profile to make it into a 'real' 3d object. It's very flexible and fast, the spline tools are very powerful.

Marcel

[Iguiniz.X.]

With objects derived from a spline you control the segments with the interpolation option (second rollout of the spline).

I knew the thing of the primitives. But what are you saying here?
Could you explainit to me? with picture's please.
I'm quite bad with the name's of the tools and bar things.
Thanks. If you want I can sent you a really small and easy program to make pic's It cuts pic's from your screen.
O and could you do the last explanation to with picture's. Pleas:)

Thanks:cool:

[Marcel]

Sorry, but I don't have the time right now to make a mini tutorial about poly editing. Besides, working with the splines is a much much better way for simple objects as walls.
(There must be tons of poly editing tut's for MAX around, so use Google)

So far, I taught two Lightwavers to use Max, and both of them were a bit puzzled with the splines, but they both learned using it in a few weeks.

About the interpolation:

If you have an editable spline (or any other spline for that matter) it has an rollout called 'interpolation'. There you can set the number of segments the spline uses to make curves with.

It's set to 6 at default, so if you make a circlular spline with 4 vertices and extrude it (make it a 3d object) the circle would have 6x4=24 segments.

That means if your circle looks blocky, you should increase the interpolation value. (If it doesn't look blocky you should try to lower it to see if you can save on polygons)

Check out the interpolation option and play with it, it's easy enough to see what it does and it's effect on objects.

Also, if you want to make some more complex objects, try out the 'bevel profile' modifier. (It's called rail sweep in Lightwave I think)

He that made a lot clear.
Thanks
