Feature Line from Alignment - Editable?

[deltacoolguy]

I have a feature line from alignment (and profile).  Easy enough to create.  The length of the alignment is 0+00 to 10+00.  I want this dynamic feature line to be only from 2+00 to 6+00, though.

I am presuming that there is no way to do this.  Is my presumption correct, or can someone lead me to the promised land?

It won't be a deal breaker if I can't do it, but it would be very helpful if I can.

Thanks.

Dear Friend,

If the profile is a surface profile you can do the following.

Use create alignment from existing alignment option from the ribbon.

The you can create the new alignment from 2+00 to 6+00 along the old alignment.

Then add the surface profile to the alignment.

Finally create the feature line.

If you have a layout profile I hope you may have a look at superimposed profiles.

Thanks

@deltacoolguy,

Great question with a direct easy answer, unless of course the question is interpreted differently. First I have created a screencast demonstrating the activities required and behavior of @Jeew-m's response to your question.  @Jeew-m, thanks for your response to @deltacoolguy's post.

In this case (screencast seen below), I made the Feature Line from station 2+00 to 6+00 as in your example.

Could Feature Lines be made to be dynamic and change when the referenced alignment changes?

• To this...I don't believe there is a way to make it dynamically linked and managed through the geometry of the referenced alignment.

That being said here is an leading article about:

  A feature line represents an object in the drawing from which you want to grade, such as a swale or a ridge line.

  Use the Feature Lines collection in the Prospector tree to manage feature line styles and layers. You can also view feature line information, such as length, elevation, and grade.

  You can create a feature line by converting existing 2D or 3D polylines, lines, or arcs. You can select objects in the current drawing or from an Xref.

Thank you both for your solutions.  After I posted the question the parameters changed and I ended up doing something slightly different, but I will keep this in mind for the future.
