# Use Dimensioning Options

You can easily add custom dimensions using Dimension mode. 

## Creating a new dimension

### Step 1 - Enable Dimension Mode

Insert a dimension by clicking `+ Create` in the [Actions Toolbar](/design/getting-started/interface-overview/actions-toolbar.md) and choose Dimension or choose `Dimension Mode` from the [Scene Toolbar](/design/getting-started/interface-overview/scene.md). This will put you into Dimension mode.

{% hint style="success" %}
**Tip**

You can also use the keyboard shortcut `Ctrl + D` to toggle Dimension mode on/off. See [here](/design/getting-started/tools-and-features.md#design-shortcuts) for more helpful keyboard shortcuts.
{% endhint %}

{% hint style="success" %}
**Tip**

You can toggle certain labels on/off to help make picking points easier. See [here](/design/getting-started/tools-and-features/view-options/display-options.md) for more information.
{% endhint %}

### Step 2 - Choose a start point for the Dimension

Click the snapping point where you would like to measure from. Intersection snaps also work for reference lines intersecting with other reference lines and member edges. The reference line hover effect is disabled in dimension mode.

### Step 3 - Choose an end point for the Dimension

Click the snapping point you would like to measure to. Hovering over different points on a truss will activate different snaps.

### Step 4 - Click the Save icon in the [Scene Toolbar](/design/getting-started/interface-overview/scene.md) to save your dimension(s).

{% hint style="success" %}
**Tip**

If you need to add multiple custom dimensions to a truss; you don't need to click the Save icon each time, you can wait until you have finished adding all of your dimensions and then click Save. Saved dimensions will appear on outputs like Truss Design Drawings and Shop Drawings.

## Deleting an existing dimension

{% hint style="info" %}
**Note**

At this time, it is not possible to delete multiple dimensions at once or to select a specific dimension to delete. Instead, they will be deleted in order from newest to oldest.
{% endhint %}

### Step 1 - Enable Dimension Mode

Choose Dimension Mode from the [Scene Toolbar](/design/getting-started/interface-overview/scene.md) to enter Dimension mode.

### Step 2 - Delete the newest user dimension

Keep clicking the Delete newest user dimension icon in the Scene Toolbar until you have deleted all of the desired dimensions.

When you are done adding/deleting dimensions, be sure to toggle Dimension mode off. Click the `Dimension Mode` button again or press `Esc`to exit dimension mode.
