Suggestion: snapping entities

Is there any easy way to snap one entity to another? For example I have block and line and i want to snap one element of block to this line. I'm doing it whith creating parallel to block segment checking angle of this parallel to line i want to snap to and rotating whole block. Then I move block to fit.
Is there easiest way or should I make feature request on sourceforge? If so I would be grateful for help with better defining this problem/request.

yes, please file a feature request at our sourceforge tracker.

Please supply as much information as possible, and better to include a test case dxf file, and/or some pictures to show the desired behavior.

Thanks!

I've made feature request on tracker. I hope it's clear, if not please delete it, I will try to make it better.
