Autodesk Civil 3D has a command "Maptrim" to Clip from a boundary.
It is similar than Fence with Fence Mode= Clip but it also removes the entities outside the boundary and the new entities outside the boundary.
The issue I see with Fence (Mode=Clip) is the user must MOVE the fence to apply the clipping.
Why not a way to "apply the clipping" without doing any operation of manipulation (move,copy,...)
Try to do this (attached annimated gif ) in MicroStation and count the steps you need..
Joan,
Are you clipping a reference file or active file elements.
For active file you would use a Void Clip fence, and for reference files the option to clip to an element already exists.
