Topic: Zoom Scale factor

[Artisan]

Ok, it has been forever since I tried to use the scale factor in the zoom command. (zoom;scale) The surveyor here is using Field Survey from Autodesk and cannot get his drawing to a scale in Paperspace. When he activates a viewport, the only way he could set it's scale to say 1:20 is to use the scale factor in the zoom command. My question is how is that done? I cannot remember how to do this to save my life. I remember something about xp is paperspace and x is model, but I am not sure. I currently use AutoCad Map and I have a toolbar called Viewports that has a drop down box to set the scale of a viewport in paperspace when activated. He doesn't have this toolbar, so there is no way to set the scale. I have never used Field Survey and he's the surveyor, so I'm just trying to be the CAD all here and fix everyone's problem. Thanks

You were SOOOO close..

I cant believe I was taught this method when I first started out!Much easier to just change the scale of the vport in properties.

Only if the PROPERTIES window is already open.  I keep the screen-eatin' PITB closed unless I really need it.

[hyposmurf]

With 2004 its just a moments click away .PITB?Punjab Information Technology Board is the nearest I can find for that.

Aha! I was trying to think of some technical CAD term!

This is what I use for scaling VP's.

Code: [Select]


(defun c:zx (/ zf)

  (if
    (= (caar (vports)) 1)
    (progn
      (prompt "\nYour not in an active viewport....")
      (exit)
      ); progn
    (setq zf (strcat "1/"(itoa (getint "\nEnter Scale Factor :"))"XP"))
    ); if

  (command "_zoom" zf)

  (princ)

  ); defun

Umm, I keep that properties tool bar open on my left monitor..

[Mark]

The problem with the VP toolbar in acad is that it's not setup for scales like we civil people use. i.e. 1:500, 1:1000, etc.........

>Umm, I keep that properties tool bar open on my left monitor

that's a good idea.

Around here it is a technical term.

Not enough desktop for two monitors, the second would have to be on top.  We're squeezed for space right now.  Maybe next year we'll add a new building and we can spread out a little.

At least with 2004 and up, you can set the properties window to autohide.  Then you only have a long vertical strip covering the screen.  I have some toolbars on the left side of my screen, and put the properties strip right next to them; it takes up only as much space as a vertical toolbar, and is easily accessible (just mouseover to expand it).

We have 6 contracts in house that started with R2002, three of them will run another 18-24 months, so R2007 may be our next upgrade.

You don't have anough room for dual flat screens??  That's gotta be one SMALL desk..  and here I thought everything was BIG in Texas.. heheh..

[CADaver]

You don't have anough room for dual flat screens??

Nope, not enough room in the budget either.

That's gotta be one SMALL desk..

As a design lead, I get 2- 30"X60" tables in a corner (everyone else gets one), one for the computer the other for the 300,000 pounds of paperwork involved in running a bleeding job.  Half the time I have to put my coffee cup on the floor with the rest of my reference material.

and here I thought everything was BIG in Texas.. heheh..

5 years ago we had a lot of room to spread out, but then we had less money to invest.  Now we have plenty of money, but no room.  We have two guys sitting at tables setup in the drawing vault.  We took in half the front lobby and added space for two more engineers.  We even have several guys scattered out in 3 conference rooms.  When we need those for meeting, the guys have to figure out who's in the meeting and go use their machines.  Even with all these new guys, we're a little short-handed, but short of setting them up in the men's room stalls, we don't have any more space available.

If anyone is interested, I created this little addition to my custom pulldown menu. In paperspace, tiled to model, just click your desired scale and viola. Of course you can add on to this if you like ie ---->
[1/20]^C^Cz;1/120xp;

ACTUALLY....if you are in floating paper space the command is...

OHHHH...you were so close!

The "S" is unnecessary

[ML]

Actually I am perfectly correct

If you were doing 1" = 10' then your scale factor would be 1/120xp
1" is representing a foot (12")
12X10=120

As far as the macro is concerned you do not use the S

It is zoom (Z) enter ( 1/120xp enter (

Did you see the pulldown menu I posted? It works perfect.

I thought that the person that started this post could make use of it

If you're really confused about scale factors and how big 1/8th inch text should be when the scale is 1:20, take a look at the CadCARD.  Just do a search on Autograph technical services.

The CadCARD is a slide rule card, printed on both front and back with one side having all kinds of drawing scale settings on it and the other having dimvars settings.  

My card sits right next to my Nostromo N52 and goes with me wherever I do Cad work.  I even have a second one for my home computer.  I't around $12.00 and worth ten times that much.  I've been using one I bought way back in R11 and it's still goin strong..

Check it out, it's worth a look.

LOL

This is  pretty elementary CAD

Listen, if you have 1/8" = 1'
Then take the 8, times it by 12 (as there is 12 inches in a foot), this equals 96

96 is your scale factor

Likewise 1/4"= 1'   ( 4 X 12) 48 is your scale factor

Now, what I was referring to earlier was 1" = 10' (Architectural Units)
Not 1:20 which is engineering units

So, once again, if you take 12 as 1 inch is representing a foot, then you simply times 12X10 and 120 is your scale factor

Of course it can get complicated if you want.

Pop Quiz:

Can anyone tell me what the scale factor would be for 4" = 5680'  

[ML]

Hey PD


I see where the confusion started   LOL
I originally put    [1/20]^C^Cz;1/120xp;

OK, that is how I display it on The Pulldown we use in work, it is short for 1"=20' not 1/20   Perhaps I shouls say 1/20'

Sorry about that

[CADaver]

15840

4" = 1 mile
1'= 3 miles
1'=15840'

[ML]

I mile is 5680' I believe

Assuming that,

If 1" = 5680'

Then

12 X 5680' = 68,160

If you divide 68,160 by 4

Then

I believe you will have 4" = 1 Mile

Scale Factor 17,040

[CADaver]

4" = 5280'

1" = 1320'

1" = 15840"

15840

~~~~~~~~~

3/8" = 1'-0"

3" = 8'

3" = 96"

1" = 32"

32

~~~~~~~~~

1/4" = 1'-0"

1" = 4'

1" = 48"

1" = 1'-0"

1" = 12"

~~~~~~~~~

3/4" = 1'-0"

3/4" = 12"

1" = 16"

OK, next topic :)

[CADaver]

Test it

IN MS draw a line 5280 feet long

Go to PS, zoom the viewport to 1/15480XP

Measure the line, it'll be 4"

zoom the VP to 1/17040xp

measure the line.

[ML]

Well, I did something almost exactly like that
I had drawn grids within grids, all on different layers with different colors.
One grid was 100 yards per square and the other grid was a mile per square, it was cool.

So, when I plotted, I had to go to 4" = 1 mile in order to plot to a D size sheet and still be able to scale with a scale rule

Hey, draw a rectangle, whatever size, then put this little macro I created into a custom button and try it

Code: [Select]

^C^Chatch;Ansi37;\45;

It utlizes Hatch pattern Ansi37 to draw a grid.

After you initiate the macro, you will be prompted for a scale factor, enteer the scale factor at the command line then pick the rectangle. You can use these scale factors below -----> Hope you like

Grid Size              Scale Factor

1/8"                          1
1/4"                          2
1/2"                          4
1"                             8
3"                            24
6"                            48
1'                             96
1 Yard (3')               288
1 Mile  (5,280')     506880

[ML]

Ps

You were right about the feet per mile 5,280'

Sorry about that. it is rhe correct scale factor above that I posted with the macro


Mark

[ML]

Also, your above scale factor was written  15480xp
I believe you meant 15840 which is
12 X 5,280' (1mile)  / 4 = Scale factor 15840 (4" = 1 Mile)
It works great for scaled site plans


Mark

[ML]

Last thing,

The Scale Factor is 63360 for a mile. Sorry again

[CADaver]

Also, your above scale factor was written  15480xp
I believe you meant 15840 which is
12 X 5,280' (1mile)  / 4 = Scale factor 15840 (4" = 1 Mile)
Mark

Typo, I can type faster than I can think.. and I type real sloooowwww.

[ML]

I made a few also as you can see  LOL
Did you try the little grid macro? It works great!

I think my brain is cooked at the moment

If we were doing 1" = 1mile, wouldn't the scale factor be 63360?

Mark

[ML]

One more correction   LOL

OK, 1 mile X 12 = 63360 if we are doing 1" = 1mile however
If you are using my above macro, keep in mind that the grid by default is 1/8" therefore, you need to do 63360 X 8 to get your grids to equal 1 mile each square. Therefore the scale factor is 506880

All scale factors i posted with that macro are correct because of the grid defaulting to 1/8"
