Capture contours and surfaces with the CADPen — fast, precise, and effortless. Go from real-world objects to ready-to-use DXF files in seconds.
Trace real-world contours directly with the CADPen — as naturally as drawing on paper. Fast, intuitive, and precise, even around complex cut-outs or freeform edges.
Create multiple sketch planes, capture contours on each, and combine them into full 3D geometry. Define sketch planes in space and build up volumetric models step by step.
Go from real-world shapes to clean CAD geometry — fast, reliable, and without cleanup.
From unboxing to your first DXF file in minutes — minimal steps, clear guidance.
Works without sprays or surface treatment, and produces results that don’t need point-cloud post-processing.
DXF export integrates with virtually all CAD platforms and workflows.

Seamless handover: export DXF from CeStudio and continue directly in your CAD tool.
The CADPen records surface points and contours with high precision — even on fine details.
All components in one transport box — light to carry, fast to set up on site.
Extend the tip (+50 mm) to reach recessed or deep points. Set the length and recalibrate in seconds.
Structured parametric geometry or freehand high-resolution tracing — switch per task.
With the CADPen, you can capture large object areas — from long contours to broad, expansive surfaces.
The CADPen is tracked in 3D within a defined working volume by two cameras. The planes A/B/C correspond to distances of 1 m, 2 m, and 3 m from the camera baseline. Refer to the graphic and table below for the working area (width × height) and indicative accuracy.
| Plane | Distance | Working Area (W × H) | Accuracy |
|---|---|---|---|
| A | 1.0 m (3.3 ft) | 0.90 × 0.80 m (≈ 2.95 × 2.62 ft) | 0.15–0.35 mm (0.006–0.014 in) |
| B | 2.0 m (6.6 ft) | 1.90 × 1.50 m (≈ 6.23 × 4.92 ft) | 0.25–0.55 mm (0.010–0.022 in) |
| C | 3.0 m (9.8 ft) | 2.50 × 2.20 m (≈ 8.20 × 7.22 ft) | 0.35–0.85 mm (0.014–0.033 in) |
