Manage surface classes
Show, hide, lock and style categories of design objects from the canvas Filters menu.
Class controls organize objects by their meaning rather than by your layer names. Visibility and class styling are project settings; they are not separate settings for each drawing page.
Open the surface classes
In the Design canvas, open Filters → Surface classes. This is alongside the Layers and Tags tabs. The surface classes are predefined; they are not user-created layer names.
Find a class
Expand the relevant class group. The panel distinguishes classes used by the drawing from Not in use classes. Expand a surface family to reach its more specific classes.
Choose visibility or lock state
Use Show, Lock or Hide for the class. Hidden objects are not deleted. Locked objects remain visible but are protected from normal selection and editing. Group controls can change the visibility of a whole category.
Set a class appearance
Use the class color or material controls to set an override. This is a class-level appearance choice; an individual object’s explicit styling can take precedence. Select an object to edit its own properties rather than treating a class override as an individual assignment.
Isolate or highlight a class
The class controls can temporarily isolate matching content, highlight it or select matches. End isolation when you want to return to the normal view. These viewing aids are separate from the objects’ normal styles.
Reset deliberately
Reset all opens Reset all class overrides?. Confirming clears class visibility and color/material overrides together. It does not preserve the class styling overrides. Use Undo to reverse a committed reset.
