I have a part with planes in it that I have created. These plans are datums for certain features. The planes will also be datums for certain components used later in an assembly. Lets say the planes are 10.000 apart. If I scale the part .500 the part does shrink but the planes still stay 10.000 apart. Why aren't the planes 5.000 apart. They were created with numbers that I input just like all the other features of the part? This makes my datums useless for my assembly.
You are right, planes don't scale, and neither do sketches it turns out. What you can do is instead of using a plane you can create a surface with the offsets you need. Then you can include the surface in the scale and use it for your mating. When you are done you can hide the surface.
the short answer is that planes are not bodies. and if you look at the inputs to the scale feature, it is just looking at bodies. sufarce bodies should scale as jamil suggested, or depending on the design intent, you could define the planes relative to feature(s) of the part, and after the scale feature. and then changes to the scale should move your planes.
Bummer. Pretty picky command. It should scale every input the user entered. No matter what it is.
Thanks for the work around suggestions.
Use the ModelRescaler macro from http://www.lennyworks.com/solidworks/SWXMacros/macbuild.asp
NOTE: This macro changes all dimensions (including plane spacing) but without creating a new feature. It's perfect for changing from metric to imperial units.
Thanks Kelvin, but I refuse to use Macros for anything. It's Solidworks responsibility to fix their Software, not ours. Plus, I wouldn't no how to use one if I had to. Does anyone really agree that sketch's and planes, which are always used for constructing everything, should not scale with the rest of the model? Pretty lame if you ask me.

Then you are missing out on many performance boosting or just plain boredom-preventing opportunities.

I agree, but in this case the Scale function is not broken. The intent of the Scale tool is to allow for shrinkage of molded, cast and 3D printed parts. It is not intended to adjust the actual size of parts.

Yes.
If you would like the equivalent of the ModelRescaler function to be included in a SW tool, I suggest you submit an ER (Enhancement Request) via the Customer Portal.
