I/O

ArchiCAD import wizard takes care of your exported ArchiCADâ„¢ geometry. it allows filtering out unwanted objects and cleans up the geometry by welding overlapping vertices - without affecting the shape - or degrading detail quality. it also creates a named selection set for every import step - allowing better scene management.

TOCollectoREX is utility replacing and supplementing standard Resource Collector.
It allows gather all scene resources together, put them in specified place, find where all missing files are used (exactly in which objects). It can find which files in specified place are no longer used by scene. It also allows convert bitmaps to jpg, etc.
Utility supports XRefs of all types and processes all scenes linked to current.
Unlike all other such scripts, it really finds all resources (images, HDR-images, Vray meshes, IES-files, shaders), not only some bitmaps (Relink Bitmaps, Resource Collector). Below there is full description.
Interface:

"Import utility for importing generic .CSM (Character Studio Marker) motion capture data as animated point helpers. New: fff"

"This macroscript is a replacement for the save function. It saves incremental file versions while keeping the name of the latest - most-up-to-date version always the same as the original file. This is good for XRef'ing because the filename does not change. Just add it to your File menu and/or define Ctrl+S as shortcut.
