Hi All,
I have plan presentation issues in Revit 2024 - the slabs, walls or columns are showing 2 lines (one solid and one dashed)
in all the previous versions of Revit, I do not have this issues!
Could someone please guide me thru this?

The following workarounds were listed on an Autodesk Knowledge Base Article and there was a recent 2024.1.1 update so make sure you have this installed.

• Change the setting for "Show Hidden Lines" from "By Discipline" to "All".
• Hide all structural columns in the view.
• Set "Edges Hidden by Other Members" to "All Edges" (only available for concrete framing elements).
