help scaling a drawing in model space

i'm working on a drawing started by someone else. They do everything in model space...no paperspace and no viewports. drawing and border are both in model space. I'm not used to just model space. 

 

How do i set the scale of the drawing in model space? do i need to use different size borders to get the correct scale? I'm drawing everything 1:1 and i need my final prints to be on 11x17 paper. 

 

on a previous drawingi see that they used a scale of 1/16"=1' but i have no idea how they determined this scale. going thru other sheets in the setd of drawings it seems that they used different border sizes (but all are printed on 11x17 paper)...some are printed not to scale if they have no set scale...like details. 

 

example of what i need to do: 

I need to show a building rooftop plan view (the entire rooftop) on one sheet. on the next sheet i need to zoom into a portion of the rooftop.

 

normally i would use viewports to do this. but in model space i dont see how this is done. do i need to have a set of different size borders? but how then can i print them on 11x17 without using "scale to fit"?

 

any help in understanding this would be great

 

thanks

You have two options:

 

1. Stick to what you know and convert to using a layout.  You could set up the viewport and use the CHSPACE command to bring the title block into paperspace.

 

2. Stick to the setup you've been given.  Use the Plot dialogue or the PAGESETUP command and set the plotting window and scale to plot from model space.

If I remember correctly the way to make borders to scale in ModelSpace is to draw an 11 X 17 inch rectangle and scale it up by the needed scale.

 

However... I would not suggest doing that. I'd start a new drawing, Xref in the drawing showing the building, Scale the xref so that one unit in the Xref is equal to 1 foot and plot from viewports in the new drawing.

 

I think doing it any other way is a path to disaster (and insanity!).

thanks for the reply...

 

i need to stick to the format i've been given (model space) but i still dont see how to set the scale. how do i "zoom" in and out on my drawing and have a set scale for each?

i guess i need a step by step on how to set up a drawing in model space. 

 

what is the size of the border/title block for 11x17 paper?

how do i set a scale?

how do i zoom in closer (without doubling the size of drawing)?

how do i set the plotting window and scale to plot from model space?

I would guess that for people who have never plotted from a layout it seems complicated to set up and use viewports etc.  But for those of us who have always done it, learning how to plot from model is a disaster.  How do you trim off the edge of something too big for the sheet?  Do you need to put your second title block on some layer you can turn off for the first plot, so you don't see a small title block showing up in the middle of your plot?

 

If this drawing has now been handed over to you to work on, you alone, then just convert it to plot from a layout.  If you need to share it with an old-timer then go the x-ref route as Allen described.

i see what you all are saying. and i agree...converting to layouts is the way to go. but if they started the drawing in model space and made it work...then there has to be a way.

You might do better using Google as your advisor.  There are a good few tips & tricks type websites out there.  I've never done it, so can't be of any more help than telling you how to avoid it.

Zoom has nothing to do with plotted scale from MS unless you plot by display. You plot by Window and either select the corners of your border or points that represent the bounds of the paper. If I have time later. I'll try to find an OLD drawing to see how it was set up.

 

I had to dump the memory of the process long ago to make room for new info.

that would be great Allen...

in the meantime, i'll start converting to layouts and let the next guy worry about it later. (bad practice, i know)

 

thanks

We had to plot from modelspace before there was Modelspace and Paperspace. I think Paperspace was first introduced in AutoCAD Release 11, which was around 1990(?).

 

What I do, as suggested in one earlier post, is make a rectange of the Plotted Size I want. If the sheet is 36x24 and I want a .5" margin all around, I make a rectangle 35x23.

 

Use scale to scale the rectangle to your plot scale, for example, scaling up 40 times would represent the sheet at 40 scale. Move it into place. Now, I always create a View using the View command. Snap to the corners of the placed rectangle. Put the rectange on a no-plot layer if you don't want it to plot.

 

Move, scale, adjust the title block as needed.

 

When you go to the plot command, in the scale area, set it to 1" = 40'. In the What to Plot area, pick View and select the View you created.

 

Most of us abhor this proceedure, but I still have to deal with it as I have some clients who refuse to use Layouts.

 

Best regards,

 

Tim

Tim,

 

Thanks for posting. Saves me the trouble of resurrecting the info from my failing brain.Smiley Happy

 

I honestly couldn't remember if you had to scale the border by 12 first before scaling by the plot scale.

Go to Dim Style, click on Primary Units, change the Measurement scale to what you need it to be. I had the same problem that you had and this is what worked for me.
