Hi Chinh, It is not possible to print out conflict reports from Tekla BIMsight. However, you can save your project as a package http://www.teklabimsight.com/helpcenter/helpTopic.jsp?topic=bim_saving_project_as_package then send the package together with a link to the download page of Tekla BIMsight to other project members to view the conflicts as well as saved views, notes, documents, markups, etc. So with Tekla BIMsight you have to think differently :) Here the software itself IS a kind of report, as the receiver can check for example the clashes in the same environment they were created (for instance, compared to pdf conflict report).
