Automotive film cutting with CADPen
Use case: Creating accurate templates for vehicle wraps, graphics and protective films.
Workflow: DXF → CAD / cutting plotter.
To protect the paint surface, the standard steel tip of the CADPen is replaced with a plastic tip and guided along a pre-applied contour tape or masking film. The system can capture both 2D and 3D contours, so flat body panels can be digitized directly on the vehicle.
For strongly curved body parts, a robust workflow is to first apply a pattern film on the car and draw the contour with a normal pen. The patterned film is then removed, laid flat on a workbench and traced with the CADPen on a single sketch plane. This generates a clean CAD curve of the film outline.
The resulting DXF geometry can be sent straight to CAD or to a cutting plotter. This enables reusable templates for wraps, stickers and fleet graphics, reduces on-car trimming and avoids any risk of damaging the paint during template creation.
