Adding Doors to Our 3D Model

Quick-Door Component

Previous 3D Model
Chapters in a project are expected to be done in chronological order. However, if you want to start from this chapter, please download the last model created from previous lesson(s) from the 3D warehouse.

The one and only door component used for the entire Project I is a Quick-Door dynamic Component. Although you can use other components, but I suggest we stick with this component because of it can be sized  accurately and scaled easily.

Because the goal is to create SketchUp 3-Model quickly and accurately, these components do not have ornamental details such as panels and fancy handles. When you have finished the entire house design and satisfy will all the dimensions, you can replace them with more better looking components or may be you can be happy by applying some wood pattern to these components.

Door Detail

The main options of a Quick-Door component are as follows:

  1. Structural width.
  2. Structural height
  3. Jamb thickness. For wooden frame, usually the same with wall thickness,
  4. First door leaf  net width (non editable)
  5. Door leave thickness.
  6. Second door leave width (0 if none)
  7. Rabbet depth
  8. Jamb width.

Doors Basic Dimension

Here are some common door specification we use during the Project One modeling:

  1. All doors height are 210 cm.
  2. Jamb thickness is the same with wall thickness (15cm).
  3. Jam width: 5 cm.
  4. Door leaves thickness: 4 cm
  5. Structural opening varies between 80, 90 and 100 cm.
  6. When a door is placed near a wall corner, a 3 cm space will be added between the door and the wall corner,

Tips and Trick
Placing and Moving Component
Placing component into a model will automatically invoke Move/Copy tool. Active at its insertion point.
An insertion point is the component's axes. Normally, the axes is placed at one of the component's corner. Use this point as the focus when placing a component to your model.
If somehow the new placed component is not selected because you click something else, select it using Move/CopyToolSelecttool tool and proceed with the component placement.
  1. Both bedroom doors are 90 cm wide.
  2. The rear bedroom door has left hand swing and the front bedroom door has right hand swing.

First, add the rear bedroom door by placing a Quick Door component on the designated wall right at the floor line. Adjust door specification using Component Options window. Move the component so it is exactly 3 cm away from a wall corner and use Measurement Box to ensure accuracy by typing [3] from your keyboard immediately after moving the component.

Use the same procedure for the front bedroom door and change it to a left swing door by flipping it using Context Menu -> Flip Along -> Component’s red.

Placing the Rear Door

The rear door is also 90cm wide. Since its location is adjacent to the bedroom door, it has to open away from the inside (out swing door) so both door leaves will not bump to each other. To do so, we need to place the door component from the inside. As usual, place a Quicky-door to a temporary location at the floor line on the designated wall. Move the door to exactly at 3 cm away from a wall corner. Just like in bedroom door placement, we need will use axis inference, but this time we are going to use red axis inference. If necessary, use SelectToolSelecttool and Move/CopyToolMovetool.

Adding the bathroom door.

The structural width of the bathroom door is 80 cm (or 70 wide door leaf). Customary, the bathroom door is an in-swing door. This is a rather small bathroom. Therefore placement of the door and the way it opens is important so it will not bump with other objects in the bathroom. The door is a right-hand swing door.

After a Quicky door component is placed at a temporary location on the designated wall, change its width to 70 cm using Component Options window. Afterward, place to its final location which is exactly 3 cm away from a wall corner and flip it using Context Menu - Flip Along -> Component’s Red. If necessary, use SelectToolSelecttool and Move/CopyToolMovetool.

Placing the Front Door

The front door is the main door so it will have a bigger width of 100 cm. Since the door is in-swing door, we need to place it from the outside of the house. However, after the door is placed at a temporary location at the front wall, we need to change our view/camera (orbiting) so the wall is viewed from the inside. We need to change this view because we want to place the door right at the floor line, which can not be seen from the outside.

As usual, after placing the door component at a temporary location, we will move it to so it there will a 3 cm space between the door and the wall corner.

Door Opening

At this point, all doors have been placed at their designated locations. Notice that each door will automatically create an opening on the wall. This is the Cut Opening feature of a SketchUp component. The opening will also move when the component is moved. However, SketchUp components can only make automatic opening only on one face. Since the Quicky Door component has opening animation, when we click each door to animate door opening, we will see that the other side of the wall still exists.


Select ToolToolPushInteract from the Dynamic Component toolbar and click at the front and read bedroom door. Since the dynamic components has animation feature, the doors will open by 45° (half of maximum door opening we set earlier)
Notice that after each opening, the other side of the wall still blocking the door entrance, especially when they are viewed from inside the room as seen on the following animation. Repeat the process so all doors are open

Creating wall opening manually.

To have more realistic model of the house, we need to manually create an opening for each of the door. Creating opening in SketchUp is a straight forward process. Just make a rectangle the same size with the door and push it as deep as wall thickness and voila … a hole is created.
However, since manually created opening will not move when the component is moved, you have to also move it manually when you move the component.

Make a rectangle the same size with the door structural opening using RectangleToolRecttool. Then, push the inner side of the rectangle using Push/PullToolPushtool. To ensure opening, use the other side of the wall as reference when pushing the rectangle.
