change of colour after patterning

Hi Krishna,

In the pattern dialog there should be a check box for 'propogate visual properties' check that. You may need to re-do the pattern for it to work.

Otherwise, select the pattern feature in the tree, go to the appearances dialog, RMB on the colour of the original feature, and click 'add to selection'

You probably have different colors assigned in Document Properties. You can change this so your original hole and "Patterned" are the same. If it doesn't screw up any colors you have already assigned (and want to keep) to model features you can Reset Colors To Defaults.
