How do you display your 3D solids ? Each solid is in an AIS_Shape object ?

Yes,each solid is in an AIS_Shape object.Because,I need every 3d solid have different color and can be select.

A suggestion :

BRep_Builder aBuilderAnnotation;
TopoDS_Compound anAnnotation;
aBuilderAnnotation.Add(anAnnotation, aShapeToDisplayed);

AIS_Shape aGlobalShapeToDisplayed= new AIS_Shape(anAnnotation);
Then, you can display aGlobalShapeToDisplayed.

This would effectively speed up the display, but how do you set a different color for each 3D box ?

Generally such large assemblies require heavy graphics and cpu.
Probably this should solve your problem.
