Remove Curves from ALignment

585 Views, 10 Replies

I just created an alignment from a polyline with several vertices. For some
reason Civil3d automatically created curves at random points. Is there a
tool that I can use to remove these PI's and curves and just make them
straight segements?

Thanks,

Francisco

You probably forgot to uncheck the option at the bottom of the 'Create alignment form Polyline' menu that says "Add curves between tangents".















To get rid of curves on existing alignments - Right-click on the alignment and 'Edit alignment Geometry'. When the Alignment Layout Tools appears, choose the icon that says 'Delete Sub-entity' and choose the ARC portion (not the straight portion). It will make your lines into a no curves alignment after you press enter.















HTH,

Thanks Rick. Yeah that was definetely
it.  Is there a way to remove these curves without redefining the
alignment?

Not that I know of. And I'm not sure why you would not want it to redefine the alignment since the curves added stationing that was un-needed to begin with. Unless I'm not understanding completely.

I will have to redefines them.  :smileysad:.  I
just was trying to avoid that since I have a lot of my corrdiors assigned to
it.  Thanks though.

HOLY CRAP DON'T REDEFINE IT!!!

 

Civil 3D's big thing is not having to redefine
things like this like you had to in LDT.

 

Right click the alignment and select Edit alignment
geometry.  Click the Delete sub-entity button and just start picking the
curves to delete.

 

Better than that, hold down the CTRL button and
pick all the curves you want to get rid of, then hit the delete
key.

To add to Matt's reply, after deleting the curves
you will need to join the remaining tangents. Just extend the ends of the
tangents until they meet and they will automatically join. By the way, all the
remaining tangents are still part of the alignment even though they
don't meet, so C3D knows to connect them when they come
together.

That's why I suggested the method I did - it is fairly painless and it will automatically join.

Crap!  I forgot that he was dealing with an
alignment from polyline.  Good catch.
