Create Smooth and Compact Shapes

The narrow curved profile helps soften angular brickwork without adding unnecessary width. It can be combined with other slopes, plates and bodywork elements to form continuous lines, layered panels and carefully shaped exterior details.

• Vehicles. Shape bonnets, roofs, wings, body panels and aerodynamic details.
• Aircraft and spacecraft. Create streamlined fuselages, engine housings and tapered surfaces.
• Architecture. Add curved roofs, canopies, decorative trim and contemporary details.
• Mechanical models. Cover internal structures with a clean outer profile.
• Custom builds. Introduce a bright curved accent or connect matching sloped surfaces.

Bright Light Orange for Striking Details

Bright Light Orange provides a vivid finish that works well for construction models, sports vehicles, futuristic designs and colourful architectural accents. The strong colour also makes this element useful for creating contrasting stripes, highlights and easily visible mechanical sections.
