reference

you know how you can reference numbers (or anything in a cell) in excel.

can you referernce numbers or strings in autocad?

eg. a floor level in model space is 15.00 can that be referenced all
throughout the drawing. (internally not externally like an xref).

so if the 15.00 level changed then you only have to change it in one spot?

 

If you have AutoCAD 2005 look into "Fields"

 

Floor level 15.00?? Is that a real world number or project-specific?

Q: When developing wall and building sections, do you actually position a floor level at Y=15.00? If you don't, you should consider trying it; makes life a lot simpler to say nothing of the math.

 

<<do you actually position a floor level at Y=15.00? If you don't, you should consider trying it;>>

Try Z=15.00

 

Please do not start another "which way is Z" argument (and make me agree with OLD-CADaver again) <g>

 

<giggle>

 

Old-Cad: You are correct IF working in 3D. If doing wall sections in 2D, I set floor elevations to actual Y-axis value. That's all.

Which way is Y depends on the orientation of the UCS (sorry Tracy). and the viewpoint setting (relative speaking) with respect to the location of your eyeballs in reference to the mean centroid of your viewing device. It's different is you have a flat screen vs. CRT monitor. (sorry again, Tracy)

 

I know, that was an apparently too subtle gig at the 2D crowd.

 

Hi Tracy,

I'm just back from vacation and so just read this. You mean to tell me that you teach this crap and STILL don't know the truth about the 'Z' thingy? I understand when you say you agree with Gacy.

Re: reference

I only have one question left. If we discover a forth dimension out there somewhere, will we have to add a 27th character to our alpha beta?

 

<<Now let me see, if I am viewing a plan view, then 'Z' would be from the floor to the ceiling, right? And if I'm viewing an elevation, then the 'Z' would be from the back yard to the front porch, right? >>

ummm... no, Z is still floor to ceiling, unless you change the UCS to something other than "World". Sounds like you haven't found the UCSVP variable yet.

 

You are doing what I asked either of you NOT do...

Personally, I do not care which axis you use, but please refrain from using
the word "crap" when describing what I and 99.99% (or greater) of the CADD
using industry (regardless of discipline) defines as it's coordinate system,
the fixed World Coordinate System. As I stated before, do not ontinue to
argue about it, you have your methods and opinions (and are rightly entiled
to them), but I do not have to agree and try and respect that, as well as
the other participants (or if you feel you must continue, please take your
arguement elsewhere (insults are not welcome).

It's a dead horse, and long overdue, please get off it.

Thank you.
