How to Scale an Assembly from 40% to 100%?

[gearhead01]

I have an assembly that was created as a model at 40% scale. I need to insert this into a different assembly that is 100% scale. Is there a way in SolidWorks to scale the first assembly by 2.5 times to make it match the scale of the second assembly?

You could save the assembly as a part, then perform a scale operation to the part.

If necessary, save the part as an assembly after scaling to regain what you had. I'd recommend saving your part and new assembly in a different directory, just to keep from messing something up or overwriting a file by accident.

Reason trumps all. And awe trumps reason.

That's too bad it was created that scale. Models should always be created 1/1 (or 1:1), 100% scale.

Why would anyone model something at less than 100%?

So it would fit on the drawing sheet?

1 inch = 2.54 centimeters

1/2.54=0.3937007874015748031496062992126

Is there a problem with units afoot? Parts modelled to inch values in a centimeter-scaled file?

Imported parts?

Is there a problem with units afoot?

I assume that was an intended pun?

The files take up less disk space if you scale them!

So, I guess if they were FULL scale they would fill the HD?

Actually, the part in question is both full scale and 40% scale, at the same time. The part was designed to fit a 40% scale wind tunnel model. This is a fairly standard automotive practice. Once the parts are developed in scale (much less expensive to produce, and 40% scale wind tunnels are much cheaper to build and operate)then that same design must be reproduced in full scale to be used on the actual vehicle. The part in question was designed to fit the scale model, so in that sense it is 100% scale, but now I need to scale it up to fit on the actual vehicle, so it needs to be 2.5x larger.

Can you create a DESIGN TABLE in the part?
Thsn scale up each dimension & keep 2 configurations?

I think the modelerscaler macro thast CBL posted will dot he trick.

Still, even in this application, I would model everything full scale, then scale the assembly down (Save as Part file first) for the wind tunnel test.

Have you tried the ModelRescaler macro I suggested in my firat post.

I never used the SCALE FEATURE until a minute ago... I don't like it. I can't "get at" the dimensions later... I loose a little functionality.

But I'll put it in my hat for later & see if I have a need to use it.

I tried the ModelRescaler macro, but it didn't change anything. I got the dialog box to open, entered my scale and hit "Apply", then the computer thought for a moment, and that was it. No change to the part. Must have tried it a dozen times, and always the same result.

I wound up just using the Scale function. It didn't scale the part's distance from the origin, so I had to manually move the part to its proper location, and I think I lose some ability to edit the part, but at least the part is the right size now.

Thanks for all of the help everyone!

This is similar to dealing with shrinkage, only bigger. (Just like a real p**** only smaller.)
Design the part the way it should be. That is the real CAD part/assembly. Create a scale configuration and make separate drawings. The real part and the scale model part should never have the same part number anyway, IMHO. All you need do is supress the scale factor for the real item. You can also do this at an assembly level, then join the parts for a monolithic scale model for testing.
Any method you use should be explainable, reproducible, and reliable.

gearhead ... what version of SW are you using? That macro was written to work with SW03. It may have to be "tweaked" to work with whatever version you are using. I know for a fact it worked well in the past.
