well i a going to buy pro...sometime , but first i want to know how do you extrude with curves



please only pictures and stuff like that (dont want to download other peoples stuff)

extrude->rotate->extrude->rotate->extrude->rotate->extrude->rotate->, etc...

Allright, I'll try, in case this is what you mean with "extruding with curves":

Basically, there are 2 ways to do this, depending on what you want to do.

1.
Let's assume the source object is a cube and you want to extrude a side polygon to make a curved arch.
Here, all you have to do is select the cube and the polygon


then extrude the polygon a couple of times, depending on the desired resolution of your arch


then, simply move the vertices up to create the curve


2.
If you want to make a more complex object, like an S, you will have to do it this way
You have the source cube again


then, you would extrude the polygon, switch to vertex mode (this will select the vertices used by the polygon), move & rotate the vertices the way you want to have it. when done, switch to polygon mode again. You will have to reselect the polygon because DeleD will select all polygons that are using one of the selected vertices. repeat this step until you've got your shape

1) how do i target and move the vertices and 2) how do i target more than 1

Like with any other item (polygon, edges, objects), use shift+leftclick to select one. Shift+ctrl+leftclick or dragging a rectangle using shift+drag leftmouse selects multiple vertices. Then use the Move command to move the selected vertices in any 2D view.

I'd like to add a little pointer to Mr. Fletcher's tutorial for curved extrusion: if you can't get the curves to look right by simply eyeballing it, it's probably due to the way you've rotated the vertices. Whenever you rotate them, make sure that the vertex you see on one side is as close to the middle between the two neighboring vertices as possible (in other words, try to make the rotation create the widest possible path around the curve...in still other words, make the line between your selected vertices perpendicular to the curve).

To illustrate:

This is a bad curve. The vertices you have selected are the orange ones, their neighboring ones (which you want to try to be directly in the middle of as much as possible) are highlighted green.

Also, the curve you're following is the green curve through the middle, and the purple line is perpendicular to that curve -- you want to have the line between your selected vertices (highlighted orange) match this.


This is a better curve. Notice how the line connecting your selected vertices is perpendicular to the curve.


This is to show what I meant by making the curve as wide as possible. The purple areas show the difference between the curve that the first shape makes and the second -- the second and better one is the one that maximizes the amount of purple you see by stretching the curve as far out as possible only through rotation.

There you go -- three ways to create a better, more natural looking curve and they all achieve the same thing. I used a relatively straight curve, but you'll see more difference if your curve is more narrowly bent. Also, this is only a general guide, I'm sure there are some instances where you wouldn't want to follow these guidelines.

Edit: I just realized that this is probably much more confusing than just eyeballing it, but perhaps someone could explain what I'm trying to say much more eloquently.

danget omg lol with every step there is a GOD DANGET, i made a bridge and when i was about to extrude the last part . i untargeted the dagon thing and when i try to target it it wont work .....target is shift+leftclick right...nvm it worked i got out of the program and entered again...is this some kind of glitch

but anyays thanks guys now i feel like a pro....not i only hit the tip of the iceburg but anyways thanks
