# Duplicate Detection

**Objective**: In this video and/or step by step walkthrough, you’ll learn about duplicate detection functionality in VECTOR tools

                         [https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/03/Duplicate-Detection.mp4](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/03/Duplicate-Detection.mp4)

#### Duplicate Detection

**Duplicate Detection** functionality is automatically implemented in **The Edge** when using **VECTOR** tools.

To best understand duplicate detection, for this example let's say we were going to perform a **mass assignment**

Select the **partition** project condition

- Set the **Scope** to **Section**
- Under **Families**, we select one of the wall types
- Click **Assign**

When we select **Yes** to apply to the entire Section, we receive message stating that there were no shapes assigned because some that you selected were previously assigned to a different page

This is the **Duplicate Detection** module telling you that even though it detected walls of this type on other pages, in 9 instances it decided not to assign those quantities.

Click **OK** or the **X** to close the box

#### Disable Duplicate Detection Warnings - Option 1

To no longer see the duplicate detection warning window, click the box next to **Don't Show Again**, then click **OK**

You can also disable the sound that comes with that pop up window by clicking the **Sounds** button at the bottom of the screen

#### Disable Duplicate Detection Warnings - Option 2

Click the **View** tab at the top left of the screen, then choose **Options**

#### Takeoff Options Screen

Click the tab **Information Sticky Note**

If the checkbox is selected beside **Show assigned/skipped # of shapes in STO assignment**, you will see the warnings. Deselect the box to not show the warnings.

#### Mass Assignment Not Detected

In this example, we click on the floor plan called **Enlarged Floor Plan - Bike Room**

Remember we worked with a P0F3 wall type and here's the **Bike Room** shown on the **Level 1 Floor Plan**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/03/Screenshot_83-1-e1647882175399.jpg)

When we navigate to the **Bike Room,**we see based on the room tag and our **families** that the P0F3 wall also exists here, but no condition was automatically inserted to the page, and no quantities exist.

So, why did the mass assign not detect this wall and map quantities?

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/03/Screenshot_84-2.jpg)

Let's clear our selection, and select an individual one of these walls, and left click on the **General** tab

Note the field labeled **Entity Key 10541686 **is the entity key ID number. Every **Revit** element extracted from a model will have an entity key

The rule for duplicate detection goes as follows: No Revit element with the same entity ID can be assigned more than once. A condition can only hold quantity for one entity key id number at a time.

On our **floor plan** we see that same **entity key ID number** for level one where that quantity was aggregated
