Click modify mass tabmodel panel mass.
Revit only shows 2 floors but the building has 3.
A level s name helps you to identify what that datum represents be it a floor level underside of steelwork etc etc.
You are almost certainly going to want to change these default names to something more.
Use the blue grip dot to drag the level head to the desired position.
That sounds like a nasty little endless loop.
See override graphic display of element categories.
You can select the mass in any type of project view including floor plan rcp elevation section and 3d views.
At the prompt click yes to have revit lt rename the corresponding views.
Model categories can have detail level set independent of the view s detail level.
Display a specific set of levels in the view and control their boundaries.
Orthographic views only adjust the position of the level head when the level is controlled by a scope box or a section box.
Mass floors are based on levels defined in the project.
This isn t an underlay nor is it a transparent floor.
Just for future reference when placing walls revit will default the base constraint to the level of the view you are in.
If you have not already done so add levels to the project.
If i start a new project from the revit template i don t get this behavior.
If you are in the level 3 plan view then the base constraint will be set to level 3.
After creating a mass for a conceptual design create a mass floor at each level defined in the project.
Architecture tabdatum panel level structure tabdatum panel level place the cursor in the drawing area and click.
For name enter 00 foundation and click ok.
Create a scope box and apply it to the view.
In addition to creating a level for each story in a building you can also create reference levels such as sill level.
Verify the detail level for the category of the element.
If you are in a level 1 view and set the top offset to level 2 the next.
Alternatively you can rename levels by renaming the corresponding view in the project browser.
Given some walls that go from level 1 to level 2 and a floor at level 2 i have a project where these walls below show thru the floors in plan.
Each level in your project must have a unique name.
In the project browser under floor plans right click level 2 and click rename.
The top offset will default to the last used value e g.
Verify that the visibility of the object s category and subcategory are enabled.
Which suggests perhaps a setting somewhere.
Open the section or elevation view to add levels to.
By default revit will name these new levels level 1 level 2 level 3 and so on.
