Getting a true scale in paper space? 3

[bot1357]

I have a drawing full size in model space. I create a viewport in paper space.

My brain is either not working today or I am just thick but how do I get a true scale in paper space?

Make sure your units are set. I presume this is a small drawing i.e. units are inches or mm. Once in paper space make sure scaling is 1:1 and you should plot full size.

You can double-click the viewport or highlight it and then select "change". A couple ways...

If you haven't already created the viewport in PAPERSPACE, execute the MVIEW command and pick two corners for the new viewport. Then ZOOM into what you wish to see within the viewport.

Then you have a couple of options for scale. While in the viewport, enter ZOOM then keyin the reciprocal of the desired scale factor followed by XP, as in 1/48XP for 1/4"=1'-0" scale or 1/12XP fo 1"=1'-0" scale.

Another would be the PROPERTIES dialog box. GRIP the viewport while in PAPERSPACE and enter CTRL+1 to "pop" the PROPERTIES dialog box. Under the MISC heading click in the box following "Standard Scale" and a small down-arrow will appear in the right side of the box. Click on the arrow, then pick your scale from the list that pops up. You may keyin a custom scale as well.

For double-click to work as described by "Borgunit", make sure DBLCLKEDIT is ON, and PICKFIRST is 1. That will "pop" the PROPERTIES box as explained above.

Sorry about this but with me just using AutoCAD to draw simple General Arrangements/Schematic loops diagrams I am not to au fait with vports! Paper space model space etc.

If I insert a vport into my A1 paper space drawing frame, what position do I give the vport within my A1 drawing frame, in order for it to be a true scale at A1?

I think I understood your reply CADaver but when I come to plot the drawing off will that scale reflect the hard copy in front of me? I don't think it will because I need to take the A1 border into consideration.

The company I work for mainly produce 2D drawings therefore I think using paper space is useless. To get a true scale I just scale my border up to suit!

The reason for my orginal post was to get a feel for paper space versus model space argument!

I am not sure if I totally understand what you are wanting, but I think I do, so I'll give it a shot.
(sorry this is so long, and if I mention things you already know!)

You say that you normally insert a border and scale it up to whatever scale right?
Ok, in paper space, you can insert your border and not scale it up. Paperspace is true size 1 to 1. So your border should measure out to be the actual size when you insert it in paperspace.
Now, within the border, you want to create a modelspace view. To do this, I would first recommend opening the toolbar called "viewports" and dock it either at the top or bottom of the screen. (if you put it on the sides, you lose part of it that you need)
On this toolbar there is a button called "single viewport"
Select this button, and then it will ask you for a corner and then an opposite corner. Basically you are making a rectangle within your border.
After you pick the second point, you will see that all of model space is displayed within that viewport.
If you double click within the viewport, it will become active and you will notice you can pan around a zoom in and out just as if you were in model space, because essentially you are in modelspace. This is called "floating modelspace".
Now, you should pan and zoom around and get the part of the drawing you want relatively centered. If you look at the viewport toolbar you loaded, you will see a dropdown list that displays the current scale (which is probably some wacky number at this point). If you select the little arrow, you will get a list of scales. Simply scroll down and select the scale you want. Now, pan around and get the drawing where you want it, being careful not to zoom in or out.
Once you get your drawing set, double click outside of the viewport to deactivate it. Now, just pick the viewport and right click and go to display locked and turn it on.
Now whenever you go into the viewport, you can pan and zoom at will, and not screw up the scale.

The great thing about this is, now when you plot, you can just plot 1:1 - You don't need to remember any scale factor or anything like that. Another cool thing about using a viewport is, if you set your dimscale to "0", you can put in dimensions and they will automatically scale to whatever viewport you are currently in.

Okay now I have a better picture of your needs.

In my example above, your A1 drawing frame will be inserted at a scale factor of one in paperspace and the VIEWPORT will be placed inside the frame.

The Major difference between that and what you do is that you scale the border up 48 times for a 1/4"=1'-0" scale drawing, but in PAPERSPACE you scale DOWN the view by ZOOMing 1/48XP, and leave the border at 1. And instead of plotting 1 unit equals 48 drawing units, you plot 1:1.


PAPERSPACE ADVANTAGES FOR 2D WORK:
The ability to control layer display independantly in each viewport. A layer can be frozen in one viewport, yet visible in the rest.

Singular drawing setup and plotting. The template will have the frame already inserted at full scale in paperspace with all PAGE SETUP in place for common plotting possibilities. Everything plots the same, regardless of scale, and its all setup once in the template.

Large area drawings that require matchlines can be kept in a single file, letting the viewports cut the drawing where required. No more going to 12 drawings to move the edge of road over 3 feet, just move it once in the model and it moves in all the drawings.

Differently scaled details on the same drawing. The frame is at 1:1, one viewport is ZOOMed 1/12XP another at 1/16XP and a third at 1/24xp. Three details, all using associative dimensions using different scales (1"=1'-0", 3/4"=1'-0" & 1/2"=1'-0&quot in one drawing.

Cheers guys, I am getting there.

I have 3 different view ports on my A1 drawing border now all at different scaling. I will just have to enter some text underneath each viewport giving the client the actual scale of each view.

That is the other great thing about using paperspace and viewports - you can have several different scales on one sheet and not have to think about it too much! (because it is still drawn in model space full size)
It makes things really easy.
