Ceiling Grid Partial Demolition

Existing Ceiling grid, need to cut (demo) new openings / holes. best way to accomplish...?

Go to the following link to set up the ceiling grid demolition pattern, not native to Revit as a default.

1. Cut holes in existing ceiling there are three ways to accomplish this, of the three below I recommend drawing the new openings inside the ceiling boundary.
Note:
_Shaft Opening  can be set as a new element while creating a NEW cut in an existing element. There is the benefit of being able to move / resize it independently of the ceiling boundary while tweaking the design. An issue I noticed is that it is not visible in a view set as an existing or demolition phase.
_Vertical Opening - good to use in an existing ceiling with existing openings or floors (single cut) since it assumes the Phase of the host element and cannot be changed.
_Another option is to just draw the opening in the ceiling boundary - I might use this for an existing opening that I'm fairly sure won't be changing for the project.
_Either one you use you have to manually draw in the ceiling to be depicted for demolition and self manage their locations, move an opening then move the infill grid. (maybe they can be locked together...?).

2. Draw in separate demo'd ceiling with new type (per instructions at link above).

3. In order to move together, Group if desired.

4. If copying openings and ceilings around, remember to set the ceiling phasing for the copied elements.

Opaque Glass

I am currently as-built modeling a building with black ribbon windows with black vision glass and black opaque (spandrel type) glass.

The problem I am having, is indicating the opaque glass panel in an elevation hidden line view.
I set a grey solid fill surface pattern to the glass type but when I do that the glass appears clear in the 3D view.

So far I have gotten the appearance that I want by using Solid fill surface in black instead. It will print heavy but accomplishes the indication required in both 3d and 2d views.

I will have to fine tune this when we get closer to publishing prints.
