Computer-Aided Design
Clear, build-ready drawings and models that support every phase of your project.
Good drawings don’t just document a building — they drive every decision that follows. Accurate dimensions mean framing goes where it’s supposed to go. Coordinated systems mean trades don’t conflict mid-construction. Build-ready documentation means the gap between design intent and field reality stays as narrow as possible. At TWG, our CAD drafting and modeling work starts from verified existing conditions — whether from laser scan data or field documentation — producing clean, coordinated drawings and Revit models in the formats your team actually uses.

Architectural
Accurate existing conditions drawings and coordinated 3D building models derived from laser scan data to support renovation and design.
Mechanical
Detailed mechanical models and fabrication-ready drawings for components and assemblies of any scale or complexity.
Industrial
Facility layouts, process diagrams, and documentation that support planning, coordination, and long-term facility management.
Visualization
Realistic 3D models and renderings that communicate design intent and support clear project understanding before construction.
