Managing Multiple Levels in the Level Overview

Last modified: Nov 14, 2018

In CET Designer, you can draw custom floors and insert additional levels to handle those multi-story buildings. To create a basic, custom floor, please see the article Drawing Custom Floors and Adding Levels.

In this article, we’ll cover how to create multiple floors and how to manage custom and multiple floors in the Level overview. Here’s a picture to show how the interface will look when you are working with multiple floors:



Level Categorization

When you place an object on a level, it will automatically belong to the level whose boundaries it is placed within. You can manually control this in the Categorization dialog where you select the level(s) that you want the selected object to be assigned to. Note that unchecking the last level will trigger the dialog to automatically reset the object to its default level(s); depending on its location.



Level overview

In CET Designer, the default setting is to show a basic rectangular floor in the 3D view that expands automatically to accommodate all objects that are placed in your drawing. This floor is labelled Base and refers to the default floor and the space that surrounds it. It will always appear at the bottom of the Level overview and entails everything that is not specifically connected to or placed upon another level.

Any time you create a custom level it will be listed here and automatically named Level 1, 2, 3 and so on (you can change the name manually).

Let’s take a closer look at what all the icons mean:

 FloorsDialogShowIcon_70  FloorsDialogHideIcon_70 Show / hide level
 FloorsDialogLockIcon_70  FloorsDialogUnlockIcon_70 Lock / unlock level movement
 FloorsDialogSolidIcon_70  FloorsDialogTransparentIcon_70 Solid / transparent level
  Level name
 FloorsDialogFloorElevation_70 Level elevation
 FloorsDialogNumberOfObjects_70 Number of objects selected /  total number of objects on level
FloorsDialogAddNewFloor_70 Add a new level on top of the selected level
CopyIntoLevel_95 Pastes copied objects directly between levels
 FloorsDialogSelectAllObjectsOnFloor_70 Select all objects on level
FloorsDialogRemoveFloor_70 Remove level

The three icons above the list are for toggling visibility, lock and solid for all levels at once.

Selecting a level in the list will highlight the corresponding level in the drawing area and vice versa.

Hiding a level in the list will also deselect the corresponding level button at the bottom of the 3D view and vice versa.



Editing a Level

Below the level list, in the Edit section, you can adjust the level in terms of name, elevation, thickness and ceiling height.

Here, you will also find a button that opens the Part Tagging dialog, since tagging levels works the same way as tagging any other components. Note that when tagging a level, the tag automatically applies to all objects placed on that level as well.

There is also a button to access the Material Explorer and the option to save a certain material as default.

Level Buttons in the 3D View

When you are working with one or more levels, new buttons become visible at the bottom of the 3D view. They are for toggling the level visibility, i.e. showing or hiding levels in the drawing.

A black border indicates your currently active level. Levels currently visible are indicated with a blue color. Left-clicking on a level button toggles the visibility, while right-clicking on a level button will change which level is currently active.

Changing the level visibility by clicking these buttons is also reflected in the Level list and vice versa.



  • When working with multiple or custom levels, the default floor labelled Base is not really considered a true floor, but rather a place where all objects that do not belong to a certain level are collected. This implies that anything that is placed upon or goes through a custom level, for example walls, belongs to that level. When you are working with multiple levels, we therefore recommend that you keep the Show level boundaries option turned on, as it will make it easier to see which objects belong to which level.
  • Not all Extensions fully support the multiple levels functionality. Please contact your manufacturer for further details.
