Collision detection not working

[Norm]

Hi,

I'm trying to locate collision in an assembly but I cant. These are the steps that I did:

1. File > Options > Config. > Enable_collision_detection > Yes > Save in config.pro

2. File > Prepare > Collision detection > Change to Global detection, Include quilts and Highlight interfering volumes

3. Analysis > Global interference > Can't select the parts which I need to highlight interference for. 

What am I doing wrong? 

Thanks

Hi,

Analysis > Global interference command checks the complete assembly. The command does not enable you to select parts.
