Scale Model Not Working as Advertised

[SarahCBaxter]

Hello,

I am attempting to scale an item I received from an outside source but whenever I try to use the Scale Model function, the assembly/part does not go under any changes. Is this because the item should have definitions within it, such as sketches to transform? The item I received had no internal sketches or dimensions, so I wonder if that is the cause? For reference I am looking to save the nominal item to a proportionally smaller size and I am on Creo 8.0.11.0

The scale model function will not work with imported data. You have not disclosed the format of the data but if the geometry is not made with Creo Parametric  geometry creation features then scale model is not going to work as expected.

Darn. Yeah, it was not made in Creo Parametric. Thank you boss.

Do you have access to Creo mold design extension? In that module there is a more advanced feature for dealing with shrink.

You may be able to use a unit conversion to scale the import data, I have not attempted this but it may be possible if you create a custom unit and use that on the part model with the import feature.

Unfortunately, I do not see the mold design extension, I do have the Mold Layout extension though. I will try to see to another way of transforming the item.

I don't know what type of data you are working with. I downloaded a STEP model from McMaster for a random clamp assembly. Attempting to scale the assembly behaved as you described; No effect. However, when I opened up one of the components in the assembly, I could scale that part. So it looks like it won't let you scale an assembly, but an individual part is okay? I didn't go any further than this, so don't know how the assembly will behave once all its bits are scaled. Seems like a tedious task, especially if there are many parts in the assembly.

This actually worked! Luckily my step assembly was only two parts. Thank you Ken
