AnisotropicPartResizer is a KSP plugin for modders that allows to resize parts anisotropically.

It is a part of the AT_Utils framework.

Unlike the TweakScale that just changes part size, APR is also capable of changing their aspect (length to width ratio). Otherwise it works alike to TweakScale, supporting custom PartUpdaters that tweak part module parameters on resize. It is, of coures, not nearly as complex and feature-rich as TweakScale.
