Linework line types by <Invisible Line>, don't show in Revit but show when exported to PDF

Question: Hi Tien, all these lines I have manually overridden the line types to be invisible, they don't show in Revit. But when I save it as PDF or export it to PDF, they show. Any ideas?

Answer: Notice the template is using Show Hidden Lines: By Discipline, and Discipline: Structural as image below

When you hit print or export to PDF, it will show dash lines as your image. Because Discipline: Structural allows showing hidden lines. But it not showing in Revit, so I think this is a bug from Autodesk. However, we can fix it. Please follow the steps below

Step 3: Linework them again in this mode

Step 4: Switch to previous template and your problem will be solved

Hope this helps!
