Set surface class, contour and fill
Change an object’s appearance while keeping its surface meaning distinct from its drawn style.
The drawing top bar has separate surface-class, outline/contour and fill controls. The Inspector provides the selected object’s supported appearance settings. A class describes what an object represents; a contour draws its edge; a fill draws its interior.
Choose what you are styling
Select the intended editable objects before changing their style. A multi-selection can show mixed values. With no selection, toolbar style choices can set defaults for newly drawn objects instead of changing existing ones. Locked or unsupported targets are not equivalent to an editable selection.
Assign a surface class
Use the surface-class control to identify the surface’s meaning. A class can supply inherited appearance. Assigning a class is distinct from choosing a direct color or material override.
Set the contour
Open the outline control for the line settings supported by the current targets, such as color, width and pattern. Check whether the contour is inherited, explicitly styled or absent before changing an individual field.
Set the fill
Open the fill control and choose its mode. Available controls can include a solid color, gradient, photo or material, together with mode-specific parameters and opacity. Only fields applicable to the current fill mode can be edited; changing opacity is not a request to create a missing fill.
Review and reuse the style
Inspect the result on the selected objects. Use the style-painting workflow to transfer supported appearance choices to other objects. Changing one style field should not be treated as replacing all other object properties.
