Intersect with clipping region, then retain elements A；
When one or more same blocks and clipping region intersect, and there is another element in the block, then whether the element is judged
Intersect with clipping region, retain the block and the element if intersecting；It is on the contrary then retain the block, reject the element.
For the rule thirdly, specifically, when a block intersects with clipping region, as shown in fig. 7, clipping region
Intersect with block B, and have Elements C also in intersection region in block B, then reserved block B and Elements C；As shown in figure 8, clipping region with
Block B intersects, but the Elements C in block B is not in the region of intersection, then reserved block B, rejects Elements C.When multiple pieces and clipping region
During intersection, as shown in figure 9, clipping region intersects with two block B, there is Elements C in block B, there is the Elements C in a block B intersecting
In region, then reserved block B and Elements C；As shown in Figure 10, clipping region intersects with two block B, there is Elements C, but two in block B
Elements C in block B is not in intersection region, then reserved block B, rejects Elements C.

1) it can be split, be separated outside rejecting picture frame border according to default automatic identification picture frame, and for picture frame border
Content, simplify splitting step, add fractionation efficiency and effect；
2) first bind, then split again for the drawing containing outer non-economic, it is ensured that the integrality of fractionation；
3) for the design drawing containing block (contain outer non-economic) or nested block, and element in block is beyond picture frame scope
Cut according to picture frame scope, rather than segment blown handled, the element or block intersected with picture frame then retains, and makes
Split process is more smooth；
4) for the drawing in drawing (layout) space set picture frame, retain interior in the range of the picture frame of drawing (layout) space
Hold, and retain the drawing model space element corresponding to paper space viewport, for the model space element beyond viewport scope
Cut, equally ensure that the integrality of fractionation；
5) cleaning reparation is carried out to the design drawing of required fractionation before fractionation, the file total size after fractionation is substantially equal to
Or slightly larger than source file size, it is to avoid there are the feelings of " split file size sum=source file size * and split quantity of documents "
Condition；
6) by the mistake in this method from processing method (as bound multi-level binding method during outer join) effectively
Fault-tolerant processing has been carried out, the abnormal factorses in drawing are can ignore that for most design drawings, to ensure in the overwhelming majority
In the case of can normally split drawing, it is possible to long-time automatic business processing, reduce manual intervention number of times；
7) on the basis of above premise, it is ensured that certain fractionation speed, for DWGs of the 2M or so containing 10 drawings
