1. ## Moving to absolutes

Hi, this a simple question. What is the easiest way to select a group of geometeries and to move them from some point and only in the z axis to some absolute? For instance, if I have a group of 2d curves and I want them to stay in the x,y but move to z 1.5 how would I go about this most efficiently. Currently, I use move; from 0,0,0 to 0,0,whatever gets me where I want to be. The problem with this is that I have to know where the from z is and do some subtraction or enter it into the from. I'd like to just move to my desired z position and not have to worry about where I am to start with. I realize I could also pick a point on the geometry and then move from there to some absolute but I run into the problem of having to then know what x,y to put in the to; that entails another extra step and extra typing. Again, I don't want to have to know anything except what absolute z level I want the geometry moved to. I've also tried the verticle option but it only seems to allow me to move relative to my selected from point.
Any advice? I'm sure I'm missing something simple.

2. what software are you running?

I'm going to take a wild guess and say Rhino.

Chris, all you need to do is use the move command and for your first pick (from point) just pick anywhere in the model. For the second point (to point) type "@" or "R" before you enter 0,0, <whatever>. This way you don't need to know, or care about, what the X and Y values are. You will need to know how much you are moving in the Z, however.

Does this help, or did I miss the point?

4. If you are just trying to move in the Z direction you want to mouse click the vertical option in the move command at the first prompt. After selecting the point to move from, like an endpoint, or just 0 for origin, you can type in an offset value to move it that much + higher, - lower. This ends up doing the same thing Dan describes, just a little easier sometimes and it only moves in Z.

5. Yes, the vertical option is easier. That option is also there for other commands such as copy, line, and probably a few more.

Did you know that you can click the options with your mouse? You don't have to type the option.

6. My point is being missed. My problem is that sometimes I have to move my geometry around in the z axis alot. How I generally figure out where to move it isn't based on where it is to begin with. Therefore, any relative movement must also be associated with a calculation of the difference between where I am and where I want to be. If I have to make this calculation hundreds of times it gets old. My ideal is to be able to just pick a point on the geometery, then to be able to tell Rhino to move the geometery from that point, where ever it is(and I don't want to have to find out), to where I want it to be. It seems that I am always having to do some minor calculation that Rhino could easily do for me. Rhino knows where the point I pick is, if I tell it where I want it to be why can't Rhino find the differnce by itself and just move it. Currently I either have to find the difference and move relative or I have to know where the x,y is and enter that into the to. I don't want to have to find out where exactly x,y is; rhino already knows!
I guess my major gripe is: why, when one chooses the vertical option and then picks a point, does the "to" value become relative? For instance, if I pick a point and then type move, pick the vertical option, then click on the point for the from, any value I then enter is relative. If I enter 0 it doesn't move to 0 it moves nowhere. The value is relative even though I didn't tell it to be relative. For my work I need this value to be absolute so that the value I enter is representative of some absolute z position.
Do you know what I mean? Pick point, tell rhino to move that point to some new z position without having to figure out where exactly that point is or how far it has to move to get to your predetermined absolute z position.

7. Okay, let's see if I have this right.

You would like to pick an object, that is say, at 100,100,100, then move it to 100,100,500 by entering only the new Z value of 500? You don't want to calculate the 400 difference?

If so, this should be easily scriptable.

8. I guess I don't understand why, when using the vertical option with "move", that the ability to move to absolute coordinates is taken away. Why can't it be like the rest of rhino and assume absolute with the r or @ for a relative movement. I can't be the only person to run into this problem.
Dan, how would one go about scripting this? I've not done any scripting before.

Dan B your right, posted this last night after work about 3 am and Rino is most likly what he's using.

10. You should post the suggestion to the Rhino support board. If nothing else, an absolute move is trivial for them to code into the upcoming Rhino 4.

Best,

11. I'll throw something together for you, but Bob is right. Ask this question on the Rhino newsgroup and you will have the attention of the developers.

12. Hey Chris,

I agree with you that there should be an easier way.

Do you always pick the same spot to move "from"? If yes, then I'd put an object at X=0, Y=0, and Z=to the object you always move from. Now you don't have to worry about X and Y. On the Move command "from" prompt, pick this new object you created and move to 0,0,0. Next, Move again from 0,0,0 to 0,0,Z=new.
