Two begginer questions

[a_n_marques120]

Hi, I've started recently using revit and I have two questions which I couldn't find answers to online.

The first is about how to hide the ceiling lines in the walls. These images illustrate what I mean.

The second question has to do with me not understanding why only the vertical walls in a section are greyed out. This is the section:

The section cuts through the ceiling and the floor, as shown in the floor plan.

Thank you so much!

First question you can use LW abbreviation of line work choose from the subcategory line invisible lines to hide the ceiling lines or floor lines showing up on the facade

Second Q2
Your visual style is set coarse and vv abbreviation of visibility graphic overrides cut pattern in coarse visual style set to gray shade check that on properties panel as you see coarse visual style set to gray shade

Perhaps Coarse Fill Pattern/Color.

Regarding first question, if the Walls and the Floors (which you are calling "Ceilings") are the same Material, you can use Join Geometry Tool to join them together and remove the visible linework between them. Likely they are both using a "BY CATEGORY" Material. Change both to the OOTB "Default" Material.
