We did it

Software for road design, highway design, street design, roadway design, motorway design, crossroad design, roundabout design, intersection design

We did it!

We changed everything starting and re-designing everything from the very beginning. We were looking for the most to give you the best: ease of use, extraordinary performance, functional design. We have decided to run with our know-how in order to create new technologies. We reflected and designed over and over as to give excellent: working environment, CAD, alignment design, input of longitudinal profiles and cross-sections, design of the road intersections. We neither gave up nor were satisfied until we found the best solution. The future of road and highway design starts from SierraSoft Roads.

Watch the video: “Mega projects.” Watch the video 'Mega projects.'


Hundreds of alignments


Thousands of sections


Millions of triangles and massive point clouds

Thanks to SierraSoft Roads it is possible to manage with big quantities of data.
Only necessary data are loaded into memory and the ones on the disk are automatically compressed in order to create small files. No more limits to your projects.

Alignment design

A new system with a few essential commands allows to solve complicated cases
in a natural way through grips, properties and intelligent objects.
Everything is displayed in real time and can be verified due to the current policy.
The alignment design has never been so easy.


Modification and control

Set to zero waiting times between the changes and the final results.

Real time update software for road design


It is possible to control the design like never before, drastically reduce designing time thanks to 3D real time cross-section on planimetry.
By changing a parameter everything is updated automatically. The result can be immediately checked even before creating the final project. Maximum control over the entire design and over every detail.
