# Ceiling Planes ## Ceiling Planes Overview {% embed url="" %}
Video Transcript:  Now that we've completed placing our bearings, we will add the ceiling planes. To simplify the workspace and reduce visual noise, let’s start by hiding the work lines. We’ll begin with the front porch area, where we’re going to place a ceiling vault with a 4/12 pitch for the front entry. Start by right clicking and selecting the Ceiling Plane tool. Make sure the slope is set to 4/12 in the properties panel. Click to place the ceiling plane along the right side of the inside wall of the porch. We will select the Insert and Repeat button, and move over to add the ceiling to the opposing side using the same slope. Click insert and escape. You are all set for the front entry. Now let’s move to the back of the structure and add the ceiling to the larger room. Right click and select the Ceiling Plane tool again. Set the slope to 3/12. Click along the back wall to place the plane. Use Insert and Repeat to place the opposing side using the same slope. Click Insert to place the plane against the interior wall. After you insert the plane is stays as the active selection, if it is not currently selected, click on it to make it active. Here we will cut the plane. While pressing the shift key, select the inside wall. Working our way clockwise, click on the opposing ceiling plane and then click to select the inside of the other wall. Select Finish Cutting. Repeat for the opposing plane: Select it. Click Cut Plane, hold Shift, and select the inside the wall to cut against. Select the opposite plane and then shift click on the adjacent wall to Finish Cutting. Let’s preview this in 3D. You can see the planes we've added in the different locations—everything is looking good. Now let's switch back to 2D to continue. Next we will cut the roof plane for the front entry we added earlier with the 4/12 pitch. Select one of the ceiling planes. Click Cut Plane, hold Shift, and cut across the front wall. Then select the opposing plane, shift click the adjacent wall. Click Finish Cutting. Repeat for the opposing plane. Shift click the wall. Select opposing plane. Shift click the wall. Select finish cutting. Let's take a look in 3D to confirm everything looks correct. That wraps up our video on placing ceiling planes.  We hope this has given you a clear insight into how you can effectively incorporate these features into your project. Thanks for watching!
## Add Ceiling Planes ### Step 1 - Create Ceiling Plane Click the `+ Create` button in the scene toolbar and choose `Ceiling Plane` {% hint style="success" %} **Tip** You can also use the keyboard shortcut `Ctrl + Q + C` to quickly begin inserting a `Ceiling Plane`. {% endhint %} ### Step 2 - Define Slope and Place Ceiling Planes Enter the desired slope and select a line to start from {% hint style="info" %} **Note** Ceiling Planes are typically defined on the inner side of the Wall. If all Walls have the same height, a 0/12 ceiling is assumed, and no ceiling planes are required. {% endhint %} ### Step 3 - Insert Ceiling Planes Click the `Insert and Repeat` button to begin selecting the next envelope. Click `Insert` to finish.
### Step 4 - Cut Ceiling Planes Right-click or select a ceiling plane and click `Cut Plane`. Cutting ceiling planes is similar to cutting [`Roof Planes`](/layout/how-to/roof-planes.md). {% hint style="success" %} **Tip** While cutting, you can hold `Shift` to cut against walls instead of inserting a vertical ceiling plane at 90 degrees. This means that, for a simple vault, ceiling planes are only needed on opposing sides. {% endhint %}
## Delete Ceiling Planes To delete a single plane right-click the plane in the scene and choose `Delete Plane` . If you would like to delete multiple planes at a time, hold down the `Ctrl` key and click each plane in the right sidebar. Once you have selected your planes, click the `Delete` icon to remove them. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
