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