Xyz, Z-z, Xz Help

[Ken_Shea]

I know that if I want say a cylinder along the X axis I have to select the y-z plane and if I want a cylinder along the Y axis I have to select the X-Z plane but I cannot mesh this idea mentally as it seems backwards to me.

What am I not visualizing here?


Thanks

Are you visualizing the side view of the cylinder or the end view? The end view is the one that is used to define the arc, and the cylinder axis must needs be perpendicular to it, so the selection process is nailing down the direction of the cylinder axis, which will always be perpendicular to the plane that is being described.

Any help?

Ken,
Bear with me for a moment, as I try to explain.
If you look at the drawing attached you will see that the different "planes" are highlighted. Normal is highlighted on top of the cube. And if you were to construct a cylinder in the "normal x-y" plane, it would start at say x0,y0z0 and extend up or down from there,(depending on your height value was pos or neg).

Keep this picture in your head.

So you could say that the x-y plane is a blanket that cover the x and y axis, but has no value in z. Does that make sense?

Now look at the drawing at x-z plane, the front of the cube is highlighted. So if you were to construct a cylinder in this plane it would start at say x0,y0,z0 and extend y plus or y negative (towards you or away from you).

So you could say that x-z plane is a blanket that covers x axis and z axis with no value in y.

Now I' m confused.

Sorry HU, you post faster than I do!

Let's see who he says cleared the issue up for him

YOU stir the water and I'll added the MUD.

I think I am going to make another pot of coffee!!, I need the caffeine to make me think straight and give the picture time to load, moving very slow today.

Hu once again you have Flung Dung
(just kidding of course, could not pass the opportunity up
The picture explanation was what really cleared it up to me, thanks Ward, thanks to you too Hu you both have been a big help.

Ken.

That makes the score:

WMS: 1
Hu: 500,510

Hooray for me!

[Ken_Shea]

In my book it is Hooray for both of you, I have read some of you two (and others) post and all I could do was chuckle you guys are so far ahead of me. I am making progress thanks to cncZone and a some super helpful members.

As soon as I figure out how I am going to change my user name to kenflungdung

Ken, Ya but you probably have a REAL life.

And I dare you on the name thing.

[Ken_Shea]

Come on Ward who do you know that is self-employed that has a "Real Life", go-ahead name one!!

I have had second thoughts on the name thing!

OK, back to what this site is about.
Have you (or others) heard any thing on the xp manual publication and do you know if they are essentially going to be the same as the built in help files?

Ken,
I have'nt heard a word, but I'll ask next time I talk to Mike let ya know. You have to admit that it's got a great online help manual though. But a manual would make great bedtime reading.
