What Is DimCon Pro?
One focused workflow for all your dimensional control processing
DimCon Pro is a macOS application built for professionals who work with 3D survey data. Whether you are processing total station measurements, validating laser scans, or preparing point clouds for CAD workflows, DimCon Pro provides the dimensional control processing tools you need in a clean, focused interface.
Import
Load CSV data with configurable delimiters, column mapping, and header handling
Process
Apply geometric fits, coordinate transforms, and station merges with precision algorithms
Visualize
Explore results in an interactive Metal-accelerated 3D view with color-coded residuals
Export
Output processed coordinates with precision-controlled formatting for Excel or CAD workflows
Key Features
Every tool you need, nothing you don't
Purpose-built algorithms and an intuitive interface designed for precision engineering workflows.
Coordinate Transformations
Apply rigid-body transforms, rotate to plane, align to north, and set control reference points. Full 6-DOF registration with optional scale, all in a single operation.
Station Merging & Control Transforms
Merge multiple station setups using common control points. Solve for translation, rotation, and scale in a single step, then apply the result across your entire dataset.
Interactive 3D Visualization
Explore your point clouds in a Metal-accelerated 3D view. Overlay fitted geometry, color-code residuals by severity, and rotate, zoom, and pan through your data.
Compare & Validate
Match points across datasets by ID and calculate coordinate deltas. Identify discrepancies and verify measurement quality at a glance with clear deviation reporting.
Flexible Data Import & Export
Import CSV files with configurable delimiters, column mapping, and header handling. Export processed results as CSV or XLSX, ready for Excel or downstream CAD workflows.
Built for Professionals
The math, handled. The analysis, yours.
