Scale in AutoCAD after Pro-E

Hello all,

I am working with engineering prints that were originally designed in Pro-E and later converted to AutoCAD. I need to make them to scale so that i can add limits to the design and later print them to scale. I have converted two over and their converstion ratios were 1:.5 and 1:.75.

Thanks

Do you have a question?

Are you working with layouts (allows access to paper space) or strictly in model space?

I believe im working with layouts. I have very little experience or training so this needs to be basic.

The one main rule of AutoCAD is that everything should be drawn in model space at FULL size. If a building is 100 meters x 50 meters that's the way it is drawn.

If you're working with layouts then you must have either one layout with two viewports or two layouts with a single viewport on each. Which is it?

Ok, heres a little more detail on what i am doing. I am trying to plot 1:1 scale drawings of hoses used for automobiles. The engineers draw them in Pro-E and convert them to autocad. From there i recieve them and have to make them production ready so material can be laid over the layout and compare it to make sure all it correct.

The plans are sent to me with dimensions and everything already in place. The problem i have is that the autocad units dont match with the actual measurements of the drawing. I was able to convert it and plotted a 1:1 scale, but i would like to make it 1:1 in the program as well.

Then it is as simple as determining the correct scale factor and then scale your geometry by that factor to make it 1:1

CS=current size

sf= scale factor

true = true size

CS x sf = true

sf = true/CS

Type Scale and window select all geometry and Enter.

Type the sf number and Enter.

Measure or dimensions to verify. (work on a back-up file in case you or I got something wrong in the workflow)

This is the simplest way to scale objects when you know what the true size should be:

Use the Reference capability within the scale command since you know what the size should be by using the dimensions.

The following scaled a 2" line into a 4" line.

Command: scale

Select objects: 1 found

Select objects:

Specify base point:

Specify scale factor or [Reference]: r

Specify reference length : 2

Specify new length: 4

Of course, instead of selecting one object, like I did, you would select all the objects.
