<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hello guys,<div class=""> </div><div class=""> I have a problem where I’m clipping two poly datas using a ‘<font color="#703daa" face="Menlo" class=""><span style="font-size: 11px;" class="">vtkBooleanOperationPolyDataFilter’ </span></font>and these poly datas were created using the result of ‘<span style="color: rgb(112, 61, 170); font-family: Menlo; font-size: 11px;" class="">vtkPolyDataConnectivityFilter</span>’ with the extraction mode set to largest region. The result sometimes returns a hollow shaped mesh although clipped the mesh is clearly hollow, whereas other times the resulting clipped mesh is properly clipped as expected with no hollow structure. I was wondering, has anyone experienced this or is there something to be done or some configuration settings that needs to be executed to prevent this from happening that I’m obviously not carrying out. Any help would be greatly appreciated.</div><div class=""><br class=""></div><div class="">Regards,</div><div class=""> Seun </div></body></html>
