Print scale?

Hi all, I need to send some dwg's for printing and I've looked at some files
by someone else.
It looks like about half are drawn full size with a template border scaled
to suit and in the rest the geometry has been scaled to suit a border (A1).
Is there a preffered method, I guess the second is more likely to be printed
accurately to scale because the first has to be print display/window/extents
(is that right?) but I don't really want to re-dimscale etc. everything.

TIA,

Mark.

 

The "preferred" (and proper) method is to draw everything at 1:1 in Model
Space, then set up Layouts at your actual paper size, with viewports scaled
as necessary to correctly display your model.

Thanks Paul, got it. Don't know why the previous dwg geometry was scaled.
Multiple viewports I'll play with later...
Thanks for the help,

Mark.

 

In Ye Olde Times (before Paper Space) one would draw the main bulk of
the drawing at 1:1 then scale the drawing sheet (including Title
Block) by the plot scale that one wanted the drawing to be plotted
at......

This was fine when one had a single drawing like a plan that needed to
be plotted at 1:50

But ( and there is always a But)

If one mixed scales of details on a single sheet then only one could
be drawn at 1:1 ( the others would have to be scaled by the difference
in scale factor from the base plot scale, so that they all printed at
the correct scale )

There are those out there that still work that way.....

There are no rights or wrongs when using CAD there are only faster and
better ways to become more productive with the tool.....

Hi Alan,
actually might come to that yet, I thought I had it figured but I'm
still trying to work out how to organise an actual relationship between
paperspace and model scale so that I end up with an actual noninal printed
scale. Need to read more about viewports but it's not imediately apparent...
Why bother specifying drawing limits if you can zoom the model in the
paperspace defined border?

Adjust the plotting of all sheets so that the sheet is the right size.

When you say you want it "to scale", do you mean a "known scale"?

If so you will have to establish the scaling factor used for the
big titleblocks, and see if that's what you want. You may end up adjusting
their
scale to suit yourself, especially if they are @ 24.61842 scale instead of
25,say.

On the shrunken stuff, if they have used a dimension style with a scaling
factor
in the annotation, you probably do not want to rescale the geometry. If the
titleblock
is the correct real size of a sheet, then just plot at 1:1. If the sheets
are NOT the right
size, you should find the scaling factor of the geometry, and if it doesn't
make sense
you might have to adjust both the scale of the titleblocks AND the plotscale
to get
the plots to end up at a known scale.

I don't envy you. I hope there's an astoundingly bright reason for drawing
stuff this way....

BTW, are all the titleblocks in MODELSPACE or PAPERSPACE, or both?
The answer could suggest a reasonable explanation for your situation.....

 

Not necessarily, Some clients require drawings to be made in model space
with the borders, text, and dimensions using scale factors to be the proper
size. The proper way to make a drawing is in accordance with the client's
requirements.

A good cad draftsman/designer will be able to deal with either method.

As far as making enlarged details, an easy way is to scale the detail up to
the size required, turn dimaso off, set a dimlfac setting (like in paper
apace) and annotate the detail. This allows the dimensions and text to be
unchanged, regardless of what some novice user does to the drawings.

I agree that the preferred way is to use model and paper space if the
drawings will always be opened and used by knowledgeable people. I have some
clients that could not possibly deal with paper space drawings. They
certainly write good checks though to pay for my services.

 

The way we work here resembles what Cadalot writes.
1 - modelsspace 1:1 , therefore if you want to draw 1:100 we make a border
in model (say A0) that looks like 118900x84100 this way we know that all
drafters can work with it and that the hatches don't give too many problems.

2 - details are often drawn on the same sheet , set the scale 1:20 draw,
hatch, annotate etc. than make a block and scale that 5 times up, ready.
(linetypes etc come out right than)

3 - when ready , we go to paper space with a ready made template (1:1 so
1189x841). In the view we set the scale 1:100 (remember, a view is actually
no more than a window to your drawing) and were done.
Plotting goes at 1:1 scale.

Simpel, not too many views, works and is productive.

As in 1:10, the guys in the workshop just love to measure drawings )

Titleblocks were all in Modelspace, to be fair a lot of the "non 1:1"
geometry was detail at a scale different to the bulk of the dwg.

Thanks all,

Mark.
