SOLIDWORKS macro renames all features in model sequentially

This macro renames all the features in active model in the sequential order using SOLIDWORKS API, preserving the base names .

Only indices are renamed and the base name is preserved. For example Sketch21 will be renamed to Sketch1 for the first appearance of the sketch feature.

Notes

• Only features with number at the end will be renamed (e.g. Front Plane will not be renamed to Front Plane1 and My1Feature will not be renamed)
• Case is ignored (case insensitive search)
• Only modelling features are renamed (the ones created after the Origin feature)
• In the assembly documents, only assembly feature are renamed (components are ignored)
• If components are selected in the assembly, features of those components will be renamed
