It is not therefore necessary to manually generate a corridor surface inĪutoCAD Civil 3D in order to export corridor surface geometry to Civil View. This consistent use of spline ordering is essential when imported feature lines are used as the basis for constructing swept objects in Civil View such as bridges, tunnels, and retaining walls.Įxport to Civil View for 3ds Max generates its own corridor surface mesh based on the raw contents of the If multiple feature lines using common feature line names exist within a single corridor region, resulting splines will be ordered firstly by start station/chainage, and then by sequence from left to right across the corridor assembly. One 3ds Max shape object will be generated for each unique feature line name per corridor region. A 3ds Max shape object may contain multiple splines, with each spline consisting of a continuous sequence of linked points. If two or more corridor baselines are references to the same alignment, a baseline will still be present in the VSP3D export file for each baseline definition.Īll corridor feature lines are exported as 3ds Max shape objects. A corridor baseline is exported as a 3ds Max shape object containing a single spline.ĪutoCAD Civil 3D, corridor baselines are derived fromĪutoCAD Civil 3D alignments and profiles.
