Breaking an alignment and using part of it for a new alignment

[Anonymous]

Ok, I give up. I have an alignment for a main road that wanders around my site. I decide that I want to shorten the main road to go through the site and make the wandering part of the road a new alignment.

Is it possible to do this? I tried to break at a PI and it 'broke' the alignment so the stationing didn't continue on the wandering part after the break. So I broke it again where I wanted the road to resume. Then I added a line from broken PI to broken PI and the stationing actually worked nicely. The problem then is that the wandering part of the road is still somehow related to the alignment (when I highlight the new shorter alignment, the wandering part also highlights. I want to make a new alignment out of the wandering part.

Thanks.

Copy the alignment. Now you have two identical alignments. Edit each one to remove/edit the parts you don't want.

Interesting...so just use the autocad 'copy' command?

Yup. You'll get a new identical alignment with a slightly modified name. "Name (1)" I displaced the copy horizontally to a new location just to make picking one or the other easier until they're edited, then moved the copy back into place.

I'll try it, thanks for the quick response.
