# 3D Takeoff: Assigning and Un-Assigning

**Objective**: In this video and/or step by step walkthrough, you’ll learn how to assign quantities from a Revit element to a VECTOR assembly

                         [https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Assigning-and-Unassigning-Elements-Part-1.mp4](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Assigning-and-Unassigning-Elements-Part-1.mp4)

#### Build Screen

Make sure you are on your **Build Screen** inside of your **VECTOR Bid**

Ensure your **Page** is selected and that it is utilizing a valid filter set

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T124631.343.png)

#### Assemblies

Make sure you have some **Assemblies** added to your **Scenario** and your relevant **Pages**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T125202.812-e1643651558292.png)

#### Perform Take Off

Zoom in on the area with some REVIT Elements

Select the **REVIT Element**(it will turn blue to show it is selected)

On the right hand side you can view all **Properties** related to this element

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T125906.347-e1643651974543.png)

For this example, we will use the **Length** dimension under the **Properties** tab to assign to our **Assembly **

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T130304.938-e1643652219595.png)

Make sure that you have an **Assembly** added to your **Page** representing this wall size or something similar

Click to select the **Assembly** in the **Bid Tree** on the left or use the drop-down box on the top menu

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T130746.734.png)

#### Assigning

Once the **Element** and target **Assembly** are both selected hover your mouse over the toolbar on the right hand side and click **Assign**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T131116.951.png)

You will receive a green toaster menu in the upper right hand corner of the window that confirms the mapping process was successful

The color of the **REVIT Element** has now changed to **Orange**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T131608.116-e1643653041253.png)

This matches the color set for this **Assembly** and its properties that gives a visual indicator that the quantities have been transferred from the **Element** to the **VECTOR Assembly**

On the left-hand side of the page in the Bid Tree, the length of 9.58 lft has been given to this **Assembly**

#### Assigning with Multiple Elements Selected

For this example we will select the G1 Single Door.

In the **Properties** Tab you can view this information under **Filters, Family Type**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T132759.827-e1643653710873.png)

Select additional G1 Single Door shapes by left clicking on them

On the top menu click the drop-down arrow and select **G1 Single Door**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T133202.709.png)

Click **Assign** on the right hand toolbar

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T133350.650.png)

The green has now changed to black to match the assembly properties

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T133859.907.png)![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T133749.154.png)

#### Assigning for Ceiling

Zoom in and select the REVIT shape by clicking inside of it

Then, click the **Properties** tab to identify this as a 2' x 4' ACT System, found under **Filters, Family Type**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T134527.986-e1643654768686.png)

Select the **Ceiling Assembly** on the left hand side

Click **Assign**

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T134807.761-e1643654918321.png)

Once it maps you will see these pieces of information as confirmation:

A green toaster confirmation message in the upper right hand corner

**Assembly** information will be filled in on the left-hand side

**Green** will change to **Pink** that matches the properties of the Assembly that were previously set

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T135051.208-e1643655302115.png)

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T135401.426.png)

#### Un-Assigning

Select the **REVIT element** containing the quantities that you want to un-assign

Choose the target condition on the left-hand side

Click **Unassign**

The quantity for the assembly is now reset to zero, the color of the element changes back to the default color of green

![](https://vectortakeostg.wpenginepowered.com/wp-content/uploads/2022/01/Screenshot-2022-01-31T135850.814-e1643655558396.png)

#### Unassigning Multiples

Click and drag your mouse around multiple elements to lasso

Click **Unassign**

Note: Only the elements that have been previously assigned will be unassigned
