I have a more than 10 number of alignments of road network in MX Road. I imported these alignments into Civil 3D. The problem is I am not able to edit these alignments.
From C3D 2012 Help: Import Tab (LandXML Settings Dialog Box) , it shows the following import options:
Alignment Import Settings
Fixed Only : All alignment entities are fixed (not constrained).
Floating Off the First Element : The first alignment element is fixed (not constrained), and subsequent elements are floating (constrained by previous).
I am using civil 3d 2011. In this Landxml import option doesn't shows an option which allows user to edit imported alignmnents.
I see, it's was a new feature with the 2012 release (I still have 2011 loaded & don't see LandXML alignment import options either).
Another option is to trace all your alignments & fillet them to intersecting PI's only and create the alignments by Draw Tangent without Curves & just add the curves in 1 by one.
Unless were talking miles of alignments this wouldn't take much effort & then they could be edited as usual.

I have more than 200 roads for 100 m length. For ease of design I made design in multiple files. But now it has become too difficult to join them into one.
