SpeedPak related queries

I have tried the SpeedPak Configuration on some large assemblies Configuration.We want to integrate that large assemblies into one main Assembly and generate the drawing.

Queries

1) If i select the entities only required for mating.The assembly performance increases but i am not getting the entities to dimension in the drawing.

2) is there anyway use layoutsketch of parent configuration in speedpak.That will solve dimensioning/mating problem.

Please suggest any approach of speedpak for dimensioning
