Read-Only Alignment after XML import

[leomal14]

Whenever I import an alignment to civil 3D, the imported alignment can't be edited through the grid view or individual entity editor. In the alignment entities menu every value for line, spiral or curve apears grayed out.

Even if I create the alignment in civil 3D, export it and then try to import it back I get this odd behaviour.

I have tried changing the settings in the xml archive in the read only section (0,1,true,false) but without luck. I have also tried every xml version without luck.

It is for me vital to find a way to import an xml being able to edit it afterwads.

I'm attaching a picture below to ilustrate my problem

Any help would be greatly appreciated

same here, very important that the line extensions be there as if you have the original elements that's of course can be edited. anybody out there knows solution.... thanks in advance...

LandXML simply imports the entities as fixed lines and curves and doesn't support all the different types of entities that Civil 3D does.
