Block clipping like x-clip in AutoCAD

[Eugen]

Blocks, exactly… I got this answer recently:

History inside Blocks?

Hi - There are currently 612 open items related to blocks, 468 of these are marked as bugs. A request for a new feature (history in a block) would likely (ideally?) be looked at after those 468 items are dealt with. We have a feature request on the list (RH-34030 - not visible to the public) for “SmartBlocks”. I have added your voice to that item. For the time being, it might be worth looking into creating a Grasshopper graph and using GrasshopperPlayer to easily access that in Rhino. -wim
