Every space you draw in Snaptrude has a Space Type. The type tells Snaptrude what kind of space it is (a room, a program block, a balcony, a road, an envelope and so on). It sets the space's default Area Type, which decides whether the space counts toward net, gross or excluded area. It also sets how opaque the space looks on the canvas. Use Space Types to keep area totals correct and to control how different kinds of space read across the whole project.

Space Types replaced Smart Labels. A space's label is just its name: typing "Balcony" or a department name into the label doesn't change how the space behaves. Set the behaviour with the Space Type instead.

Each Space Type comes with a default Area Type and a default opacity:

Program Block and Envelope are 30% opaque by default. That way you can trace PDF, image and CAD underlays through them and show massing as translucent volumes in 3D.

A space takes on the defaults of its new type, including its Area Type and opacity. The Space Type can also change other defaults, such as the space's height and material. Height Lock is on by default for every Space Type. To check which type each space has, switch the canvas color mode to Texture.

Tip: To select every space of one type, right-click on the canvas and use filter select By Object, which lists Space Types. To select spaces that match one you already have selected, right-click it and choose Same Type.

Area Type controls how a space's area is counted. There are three values: Net, Gross and Excluded. Each Space Type sets a default, and you can override it for any space.

You can also set the Area Type in Program Mode. The program data sheet has an Area Type column with a dropdown for each space. This is a quick way to reassign spaces that came in as Room but should be counted another way.

Excluded spaces don't add to your net or gross totals. To review them, open the Areas tab in the right panel and switch the area dropdown (set to Carpet Area by default) to Excluded Area. You can also filter the Areas tab by type.

Opacity belongs to the Space Type, not to individual spaces. When you change it, every space of that type in the project updates. The value is saved with the project and synced live to everyone working on it.

Note: You can't set opacity on a single space. To make one space look different from others of its type, give it a different Space Type.

Envelope is the Space Type for buildable envelopes and massing volumes. Its default Area Type is Excluded, so envelope area doesn't inflate your net or gross totals. Its default opacity is 30%, so you can see and work with the spaces inside it.

Opacity works at two separate levels, and they combine:

To change fills for a presentation without affecting the model, adjust the view style settings in Present Mode and leave the Space Type opacity as it is.
