[1143413815422067]

When I set up a new type of Level in the Type Properties Dialoge by using the copy button, I can't find this new type in the Project Browser.
And then,How to delete this type of the Level?

When you say "Level", are you selecting a Level grid in an elevation or section and setting up a new type? Or are you viewing a "Floor Plan" or selecting a "Floor Plan" in the Project Browser and setting up a new type?

The latter will create a new Floor Plan view type and depending on how you have your Project Browser organized, it will create a new category of views in the Project Browser of the new type.

If creating a new "Level" (grid), that does nothing to your Floor Plans in the Project Browser. It is usefully to create Level types if you want some to show elevation above sea level and others to show elevations above a relative point, for example.
