I am using microstation v8i ss4 I get these unwanted dots in pdf when converting the dgn to pdf. These contents were converted from suppliers pdf drawing to dxf and then taken into dgn. When I print the pdf the unwanted dots appear. How can I hide or…

Please look at the snapshots below. The left one is dgn and right is the pdf. Can anybody help me to get the actual shape of the elements in pdf as in dgn. Can anybody tell me whats the problem with this.
