How to scale

18532 Views, 6 Replies
04-29-2007 10:14 AM
I am working on a Reflective Ceiling Plan. I found a legend on cben.net that includes many of the symbols that I need to use. I copied and pasted into my model space. The scale on the copied objects is not correct. Is there an easy way to select objects from the copied items and scale accordingly? My current scale is 1/4". As you can see I'm a new user. Any info would be helpful.

Thank you!

You should ALWAYS draw 1:1 scale in AutoCad
Then when you insert blocks of objects that are drawn to
scale, they will insert at the correct scale. But since you said
your drawing is draw at 1/4 scale, you will need to scale down
your object by .25 Hope this helps, if not select all of your current
drawing
(Without the pasted objects) and scale up by 4.
Hope this helps

Good advice. But if scaling down by .25 does not work try scaling up by
48. I am thinking 1/4 means 1/4"=1'-0"

Since you didn't mention what scale it did come in, you might not be able to
just scale by .25, 4 or even 48 for that matter. So I would suggest "align",
look it up, as it would take longer to explain.



Or a method that I like to use. Here are 2 different ways.



1. scale an object that is not the correct size. For example scale a light
that you know should be 48x24. say it is 58 1/2". therefore do the
calculation (*the first number is always the size you want it to end up as):
48/58.5 = .8205 So scale down all of your inserted objects down by .8205.



2. Or you can do this same command without a calculator. Pick all objects to
scale, pick base point, then type in 'cal (then return) now punch in your
calculation again - 48/58.5 (then return) and done!

note that you cannot use fractions in this calculation.



Once again "align" will do the trick also, maybe even better, as it will
move, scale, and rotate all at once without any calculations, just pick
points.

hope this helps.

Another option I am particularly fond of for scaling is using the scaling with reference option. I like my objects to be "exact" and taking measurements from an object is always subject to rounding, so I try to avoid using calculations. Using Geometry is much more accurate and usually involves no math at all. Pick a point on your current object that we shall consider the base point. Draw a line, circle, or other geometry to the length you want it to be to create some geometry to snap to. Begin your SCALE command, selecting your base point to start. You should notice in the command line an option to Reference, type "R" to evoke this option. Next pick the endpoint of your inserted geometry then next pick the endpoint of the "desired" distance(or quadrant, depending upon what geometry best suited your need).

A bit of practice and you can get any scale with any object without spending any time calculating scale factors.

Why take the extra step of drawing a reference obejct when you can just type
in the new reference length? I can understand using existing objects as
references, but not drawing new ones just to erase them.

I'm glad you asked that question. I had been under the assumption that if the direction wasn't true horizontal or vertical, that a typed in value would change the direction of the scale to the direction of the pointer location on the screen and thus would affect the length and/or angle (thus why I created temporary geometry to snap to). A quick test revealed that theory was incorrect and it worked great.
