Cut a new section elevation to inspect the vertical position of the grids are the missing grids associated with a scope box in the project.
Revit roof not showing in section.
Typically when you cannot see an object as expected in a view the issue is an incorrect visibility setting.
This process can help to isolate many crossover visibility issues that arise in phasing and family creation.
If working in a version of revit prior to 2019 or if reviewing the levels in a 3d view does not resolve the issue.
Also check the discipline setting for the callout view perhaps changing to coordination might do the trick.
If this is the case the grids won t show in the your view.
Please note that your view might have a cut plane outside of a defined scope box which the grid lines are associated with.
Try turning off the far clip plane for the section or elevation view.
Though from long autocad background i m creating a basic dormer with in a roof but the but the roof does not appear in the level.
Hi everyone my fist post and im quite new to revit.
Use this checklist to troubleshoot why objects are not visible in a view.
I can see the side walls and the walls that define the dormer but not the roof that should sit on the same view wither joining the walls or at the front south of the building.
Try to recreate the error in a new empty project.
