Single Carriageways

Single carriageway design can be challenging, especially keeping all the objects dynamic. Devotech iDAS provides tools to dynamically link drainage and guardrail details in the profile views (longsections) with the corridor.

Another major benefit is that Devotech iDAS can dynamically link profiles with the corridor so that the road edges' profiles are dynamic, and do not need to be recreated every time the design changes. Devotech iDAS also contains a subassembly for cut/fill based on SANRAL (South African Road Agency) requirements.

Dual Carriageway

Dual carriageways can have a complex geometry with different horizontal and vertical alignments for each carriageway. This introduces various width and height differences at the median. Devotech iDAS has a tool to dynamically link profiles to corridors, allowing it to link the median geometry to carriageways so that the entire corridor updates automatically. Other tools allow the user to dynamically link the drainage and guardrail details in the profile views (longsections) to the corridor.

Devotech iDAS also provides various subassemblies which can be used for dual carriageways:

Urban Roads

Urban road design requires many repetitive tasks, which can be minimised by using Devotech iDAS. Road centrelines are often available as polylines. Devotech iDAS has a command which converts polylines to Autodesk® Civil 3D® corridors. All the objects are created automatically including horizontal alignments, profile views, vertical alignments, corridors, top surfaces, datum surfaces and sample lines. The designer just needs to focus on the actual design by adjusting the objects. Devotech iDAS also provides tools to create intersections automatically, to change labels for multiple alignments at once, modify multiple profile views (longsections) and section views (cross sections) in terms of height and datum, as well as tools for quick navigation within the drawing (zoom to alignment, zoom to profile view).

It is often required to design a channel on the low side of the road and a barrier curb on the high side of the road. Devotech iDAS contains a conditional subassembly which automatically determines whether the road edge is on the low side or high side, and applies the appropriate subassemblies.

Devotech iDAS also provides tools for plan production so that the plan and profile sheets can be created for all the roads simultaneously.
