TCM ROADS in your CAD environment
Terrain, alignment, intersections, longitudinal and cross sections — clearly arranged on the ribbon, with access to the project panel and software updates.

One connected system
Geometry changes carry through linked project views, while annotation, quantity and documentation tools speed up everyday tasks.
Commands follow real design stages, with clearly organised ribbon modules and direct control in the DWG environment.
TCM ROADS is developed as a dynamic system: changes in plan view or cross sections are reflected in linked parts of the drawing. Terrain, alignment, vertical geometry and profiles form a coordinated design.
Dimensions, annotations, tables and quantities follow engineering practice and the requirements of the Serbian market.
A modular system
One project, connected modules. Select a discipline to explore its part of the design process.
DIGITAL TERRAIN MODEL
Import and process survey data, select elevation attributes, organise project locations and make local terrain model corrections.
Tools in practice
Explore some of the commands you will use on a project. Launch them from the relevant module or enter their names in the CAD command line.
Terrain
Create a triangulated network from points, with breaklines and terrain boundaries.
TCMTERFACEPoints and boundaries → 3DFACE terrain model.
Terrain
Select block types and the attribute containing the Z elevation.
TCMTERBLOKSurvey blocks → points with elevations.
Plan view
Create an alignment from two selected polylines, with settings in a dedicated dialog.
TCMOS2PLTwo polylines → road alignment.
Longitudinal profile
Open a comparison of vertical alignment alternatives and review different elevation designs.
TCMPROFCOMPAREVertical alignment alternatives → comparison view.
Cross sections
Define pavement layers with a dedicated tool and display them in cross sections.
TCMPOPSLOJLayer properties → pavement structure view.
Annotation
Label cross-section elevations with a choice of symbols and annotation styles.
TCMKOTVISINAProfile points → elevation labels.
Intersections
Start creating a roundabout. The module also includes commands to edit, refresh and manage approaches.
TCMKRUZCRTIntersection parameters → roundabout geometry.
Quantities
Open the volume calculation linked to the cross sections of the selected alignment.
TCMZAPREMINACross-section data → volume overview.
Before using geometry and quantity commands, prepare the required terrain, alignment or profiles in the drawing.

QUICK START
From installation to your first drawing. Start with a copy of a project and explore the tools at your own pace.
You need 64-bit Windows 10 or 11 and AutoCAD or Civil 3D 2026. TCM ROADS is an add-on that runs inside your CAD application.
The CAD application is installed and licensed separately.
Save your work and close the CAD application. Download the current installer and follow its instructions. Open your supported CAD application and follow the TCM ROADS activation instructions.
Download the free trial and follow the activation instructions.
Work on a copy of your DWG. Prepare survey points and terrain boundaries, then explore terrain, alignment and profile tools in that order. Check the units and elevations before calculating quantities.
Use the command reference below to find the tools you need.
