There is hundreds of chairs like this on the picture. Is there an easy way to replace them or to reduce the polyline segmentation?

When I import them in Ac12, I get each file around 25 Mb, so when I copy all on the same floorplan I get over 120 Mb size pln. My machine gets terribly slow. I have tried line and fill consolidation but with not much reduced file size. Any sugestions?</T></DIV> Thu, 23 Jul 2009 08:44:19 GMT https://community.graphisoft.com/t5/Collaboration-with-other/DWG-grows-when-import-to-AC/m-p/162166#M18391 Anonymous 2009-07-23T08:44:19Z https://community.graphisoft.com/t5/Collaboration-with-other/DWG-grows-when-import-to-AC/m-p/162167#M18392 I think I got it.
