Meshing issue

Hi 

Please see attached example model for industrial sized slab, with a big foot print but small foot prints for column stubs and equipment footings. I have few queries:

1. how can i increase density of mesh at density points so that i have better results. i have tried to inflate density to x100 but that results in skewed and bad topology of plates specially at density points: 1 to 10.

2. how can i pre -set the aspect ratio of FE plates so that skew -ness is reduced.

3. For the small pedestals shown I am trying to use the master -slave command so that I can apply load on bigger foot print without having to specify multiple nodes to represent the footprint. I will applying the resultant loads to higher nodes modelled.communities.bentley.com/.../master-_2D00_slave-_2D00_test.std

thanks.
