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)
