parts or derived objects scaling

why every tutorial on the internet about scaling parts or derived objects talk only about scale factor, this is cad software, we do things with precision, scaling is a basic operation for such a software, we need to scale with specific dimension, referencing should have freedom from any points not by scale factor like they do in youtube, scaling by 2, 0.5 etc. i cant find an answer to this like scaling every unknown dimension of existing object to a desire dimension, like scaling overall height to a specified dimension or scaling from a reference point to another point so the rest of the parts followed.

If you are importing something and need to scale a certain dimension, you can use a measured variable and set the scaling factor to "desired dimension"/"measured dimension". You can use separate factors for x/y/z.
The "proper" way to handle variable sizes like this though is to design your parts using "configuration variables".
but the existing part's dimension is unknown so the value for the formula of "measured dimension" is unknown, i tried to measure a caster wheel from bottom of the wheel to the top most part of the mounting plate but cant find a way to do this. i have made a framing and use a public model of caster wheel, but i need to scale it to a desired height proportionally.
If you can share the model it's much easier to help.
Generally, if the model has irregular shapes the measure tool can't reference, best route is to make intermediary sketches off the geometry to get stable sketch references to measure from instead. And then use the scaling factor calculation Eric recommended.
