Forge Viewer now supports the translation of Civil 3D drawings, including its specific data. This allows some basic workflows for non-Civil 3D users, like approval process, which is usually related to a design check. This sample demonstrates a basic approach to verify radius of Alignment curves against a minimum requirement, very simple, then show a Viewer docking panel with the list of alignments and respective curves approved or not approved.
A first prototype of this extension is available here, you can also test it here (as shown in the video above)
