Todo Terreno CAD (TTC) Suite is a professional-grade engineering automation platform for Autodesk® Civil 3D® designed to streamline the transition between raw field survey data and final infrastructure design. Engineered in Panama under the strict "Surgical Cleaning" protocol, this suite ensures high-performance calculations without compromising drawing stability or data integrity.

The suite integrates 15 specialized tools focused on three core engineering pillars:

I. ADVANCED SURFACE & GRADING ANALYSIS

TTC_SURFACE-AREA3D: A high-speed bulk analyzer for TIN surfaces. It calculates the true 3D surface area and perimeters of multiple surfaces instantly, placing automated centroid labels and generating exportable CSV reports.

TTC_POLY-SLOPE: A precision projector that generates daylight/zero lines by projecting cut and fill slopes from a base polyline onto a target terrain.

TTC_SURFACE-SLOPE: Automates grading between surfaces by projecting slopes directly from a design boundary onto a target model.

TTC_POLY-OFFSLOPE: Allows for parameter-based 3D offsets using fixed distances and ratios, ideal for road shoulder and berm design.

II. TOPOLOGICAL GEOMETRY TOOLS

TTC_POLY-PERIMETER: Employs the "Double Walker" algorithm to extract precise concave boundaries from COGO point clouds, far superior to native convex-hull methods.

TTC_POLY-UNION: Fuses complex polylines that touch or overlap into a single, clean entity by surgically removing redundant internal segments.

TTC_POLY-DENSIFY: Increases geometric resolution by inserting vertices at fixed intervals, essential for precise terrain draping and slope accuracy.

III. COGO POINT & UTILITY AUTOMATION

TTC_POLY-2DTO3D: Transforms 2D lines into intelligent 3D geometry by automatically retrieving elevations from the nearest available COGO points.

TTC_POINT-KILL: Identifies and cleans overlapping survey shots based on user-defined priority logic (Newest/Oldest).

TTC_POINT-INPOLY: A spatial exclusion engine to isolate or bulk-delete points inside or outside complex boundary polylines.

GLOBAL COMPATIBILITY: TTC Suite features an internationalization architecture supporting 9 languages: English, Spanish, French, German, Portuguese, Russian, Japanese, and Chinese. All tools operate 100% offline, ensuring maximum data privacy and performance.

TRIAL PERIOD: This professional version includes a full 30-day free trial so you can experience the efficiency of the "Surgical Cleaning" workflow in your real-world Civil 3D projects before committing to the $3.99/month subscription.
