Smart Object Select

Smart Object Select is a blender addon, which is used to make smart selections of mesh objects.

It is possible to select by:

Name

Select one object and set the split parameter and all object with the same name (all that match in the name before the split parameter) will be selected.

Volume

Select one object and choose:
> - The object and alla objects that have the same volume and greater volume then this object will be selected
< - The object and alla objects that have the same volume and less then this volume will be selected
= - The object and alla objects that have the same volume will be selected
Volume Match in % - Value to set how good match in volume it should be, 100% = perfect match and 0% no match at all (all will be selected).

Faces

Select one object and choose:

> - The object selected and alla objects that have got the same numbers of faces or more faces will be selected

< - The object selected and alla objects that have got the same numbers of faces or less faces will be selected

= - The object selected and alla objects that have the same number of faces will be selected

Face Match in %

- Value to set how good match of faces it should be, 100% = perfect match and 0% no match at all (all will be selected)

Smart Select

 All objects that are most likley the same will be selected

Smart Match in %

- Value to set how good match it should be, 100% = perfect match and 0% no match at all (all will be selected).

Remove Objects no faces
All objects that have zero faces will be deleted.

AutoRename Objects

All objects that are likely to be the same will be renamed with the same name.Starting at Part1000_PRT, Part1001_PRT and so on. 
Perfect for getting an order in an imported assemblies where each object has its own unique name instead of the same name on similar objects.

Instances of object:
The addon also support if objects are instances of each other.

Good to know
Because some features require a lot of processing power, it can take a very long time for the addon to use the features. For example, select by volume.

It is strongly dependent on the object's mesh. More mesh information more time consuming.
