Making doors look right in different ortho views

While I was putting together this post last month, it dawned on me that doors are represented differently in plan, elevation and sectional orthographic views of a building. By which I mean:

  • In plan, doors are generally shown in the open position.
  • In elevation, doors appear closed.
  • When cut through in section, doors disappear altogether.

In plan, doors appear open to show their swing. In the above image, the swing arcs, section cut graphics and arrows were added in LayOut.

In elevation, doors appear closed. Otherwise, you'd be able to see through them, which would be visually confusing. The scale figure and the dashed lines to indicate the hinge position were added in LayOut.
sectional views
In sectional views, doors which are cut through don't appear at all. All that is visible of the doorway in the above section is the edges of the wall beyond the cut. Doors which appear in elevation (like the one on the left) are shown closed.

If I’m modeling a building and I leave the doors open, they’ll look correct in plan but not in other views. If I close them, the plans will look wrong. Clearly, I need two sets of doors—one open, one closed—and I need to manage which set is visible in each view. Layers, Scenes and nested components to the rescue!

The idea here is to create a door component that includes two sub-components: one that’s an open door, and one that’s a closed door. Mine looks something like this:

A door component which includes both open and closed door sub-components, each on its own layer. In the image above, "Color By Layer" is turned on to better illustrate the setup. The Outliner dialog box shows the nesting relationship of the three door components.

Creating a combination door component

Start by modeling both doors and turning them into a set of nested components:
Step 1
Create the hole into which you want to insert a door.

Creating a combination door component
Make the hole exactly the same size as the door you're planning to model.

Step 2
Model a door in the closed position. Keep it simple; a rectangle is fine for now.

Door-36-L-Closed
Fill the doorway opening with a simple face. Make it flush with the side of the wall into which the door will open.

Step 3
Select only the door geometry and turn it into a component. Give it a meaningful name that describes its size, orientation and position like “Door-36-L-Closed”.

Door-36-L-Closed
Give your door component a meaningful name; "36" indicates the width and "L" indicates the left-hand hinge position. Make sure the "Replace selection with component" checkbox is selected before you click Create.

Step 4
If you like, add detail (like a thickness) to the door you just modeled.

Extruding the single face into a 3D object
Extruding the single face into a 3D object will make it read better in plan. Resist the temptation to add doorknobs, detailed woodwork or anything else that isn't in keeping with your model's current level of detail.

Step 5
Model the same door in the open position. Be sure not to duplicate the component instance you made in the previous step — the whole point of this exercise is to have two, separate components.

Door-36-L-Open
Model the same door again, this time in the open position. For accuracy, line up the edges where the hinges would be on a real door.

Step 6
Turn the open door into a new component. Call it something like “Door-36-L-Open”.

Door-36-L-OpenDoor-36-L-Open
Make the open door into another component and name it accordingly.

Step 7
Select the open and closed door components and make a new component that includes both. A good name for this component might be “Door-36-L-Main”.

Door-36-L-MainDoor-36-L-MainDoor-36-L-Main
Select both door components (open and closed) and make them into a new component.

Using Layers to control component visibility

The next step is to put each sub-component on a separate layer:

Step 1
Choose Window>Layers to open the Layers Manager.

Step 2
Create a new layer called “Doors-Open”.

Step 3
Create another layer called “Doors-Closed”.

new layer called “Doors-Open”
Use the Layers Manager to create two new layers.

Step 4
Choose Window>Entity Info to open the Entity Info dialog box.

Step 5
Start editing your Main door component (the one that includes both sub-components) by double-clicking it with the Select tool.

Step 6
Select the closed door sub-component and move it to the “Doors-Closed” layer using the Layer drop-down menu in the Entity Info dialog box.

Doors-Closed” layer
Move the Closed Door sub-component to the "Doors-Closed" layer using the Entity Info dialog box.

Step 7
Select the open door component and move it to the “Doors-Open” layer.

Doors-Closed” layer
Put the Open Door sub-component on its own layer, too.

Step 8
Click elsewhere on your screen to stop editing the Main door component.

Doors-Closed” layer
Make sure the Main Door component (which includes both sub-components) is on LayerO. If you're really advanced, I suppose you could even have a layer dedicated to these "combo" door components. Tread lightly, though—layers can be tricky to work with.

Setting up Scenes to control layer visibility

After you’ve placed doors wherever you need them in your model, you can control which set is visible by creating (or updating) scenes that show only one “Doors” layer at a time. It’s pretty straightforward, really:

Step 1
Activate the scene that corresponds to a plan view of your model. If you don’t have one yet, just create a new scene called “Plan” and worry about getting the camera position in order later.

Doors Closed and Doors Open layers
Right now, both the Doors Closed and Doors Open layers are visible. We only want the open doors to appear in the above plan.

Step 2
In the Layers Manager, hide the “Doors Closed” layer.

“Doors Closed” layer
Uncheck the Doors Closed layer to make its contents invisible.

Step 3
Right-click the “Plan” scene tab and choose Update.

Right-click the “Plan” scene tab
When the doors look the way you want them to, right-click the relevant scene tab and choose Update.

Step 4
Repeat the above three steps for any other planimetric scenes in your model.

Step 5
Go through the above process again for any scenes where doors should appear closed.

Doors Closed layer to be visible
In the above elevation view, I want only the Doors Closed layer to be visible.

Dealing with doorways in section

What about doors that are cut through by section cuts? They shouldn’t appear at all. The solution here is simple: Just hide the offending door components and update your scene.

Dealing with doorways in section
Doors which are cut through in sectional views shouldn't appear at all. Those which appear in elevation (like the one on the left) should appear closed.

Simply hiding door components you don't want to see (then updating the corresponding scene) is the easiest way to deal with this conundrum.
