Here's a trick for dealing with self-intersecting clip boundaries

Mike Carter shares a trick he developed to deal with self-intersecting clip boundaries.  We often will xref our first floor plans onto our second floor plans and then create a rather involved pline to use as a clipping boundary for the xclip command to mask off parts of the first floor xref that we don’t want to be visible on the second floor.   Later modification of this pline often results in the error “self-intersecting clip boundaries are not acceptable” when we begin to redo the xclip.  Instead of redrawing the entire pline or trying to find where the (almost impossible to find) problem is, just offset the pline by 0.1” or some very small amount.  When AutoCAD generates the new offset pline shape, all self-intercepting problems are cleared out and the new pline works as a clipping boundary every time.  Offset a second time if you want to retain the exact dimensions of your original pline.

NOTES FROM CADALYST TIP PATROL:  This is a great trick that should work.  I can’t say that it will work every time because I can’t test every scenario.  BUT what I did test on did work.  If it doesn’t, try offsetting to greater distances.  Tested in AutoCAD 2009.
