Understanding Classes

Learn how classes control object appearance, attributes, hierarchy, and visibility across a scenic drafting file.

What to notice

Classes are the graphic control system of a Vectorworks file. They do not hold the drawing the way design layers do; they define how objects look, organize, and show, gray, or hide across saved views, viewports, and drawing contexts.

A strong class system lets a file stay visually legible even as the drawing becomes dense. Line weights, fills, textures, and visibility can be managed consistently instead of adjusted object by object.

Scenic drafting depends on that control because drawings mix architecture, dimensions, scenic objects, masking, notes, and 3D elements. Classes let those categories behave predictably across views.

The workflow

Name: Use class names as structure

Hyphenated class names create hierarchy, so related drawing categories can stay grouped and searchable.

Class names should describe graphic purpose, not only object type.

Style: Let classes carry attributes

Class attributes are powerful because they standardize linework, fills, and textures across objects.

Use at Creation turns the class into a style rule instead of a label.

Visible: Control what the drawing shows

Class visibility can clarify a drawing without moving objects to a new layer or deleting information.

Visibility is one of the main ways classes support documentation views.

Class attributes: Class-controlled or manually overridden

Check the difference between an object that follows class attributes and one that has been manually styled.

  • Class-controlled objects revise globally.

  • Manual overrides can hide drafting standards.

  • Visibility can be managed without moving geometry.

One guiding idea

Classes make a drawing easier to trust because graphic standards stop depending on memory.

01 Classes describe graphic behavior

A class is not a place where an object lives. It is a set of graphic and visibility instructions that can travel with that object across the file.

That difference is what separates classes from design layers. Layers organize drawing planes. Classes organize how objects appear and whether they are visible in a given view.

02 Use at Creation keeps standards intact

When class attributes are used at creation, an object can inherit the correct line weight, fill, color, texture, or visibility behavior automatically.

That makes the drawing more consistent and easier to revise. Instead of selecting dozens of objects to fix a graphic standard, the class can carry the standard for the whole category.
