Converting profile to feature line

[Aistis88]

Is it possible to convert profile to feature line ?

In 2012 I open a copy of the drawing and explode the profile until the 3D Chain is a polyline and create a featureline from that. You may want to increase the tessellation of the Chain before doing that. I believe that in later version you may be able to extract a featureline directly. Select the profile and check the ribbon.

Create Feature lines from Aligment will allow you to create a FL over the aligment using elevations from a selected profile.

Thanks for tips. I used subassembly to get feature line. I gave profile as target to subbasembly point and then i created a corridor , and from corridor i took that feature line .

Thanks Jeff. I knew there was a better way but was looking in the wrong place. Is there a way to control the tessellation on that without changing the frequency of the Corridor.

I have not been able to find a good way to control the tessellation in 2012. There are settings for tessellation of spirals and a mid ordinate distance. I don't use spirals and the mid ordinate settings do not behave as I would expect. With that said, the settings in my template have always worked fine for my needs (mid ordinate 0.05, spiral tessellation 0.25)

I did a quick test using the Profile-5A tutorial drawing. The lower F/L used a midordintae of 0.10, the other used 0.01. Definitely shows a better following of the VC's.

I was looking at the horizontal curves. Some of the F/L's I created from alignment had not elevation points (like your example. Others had elevation points about every 5' and that spacing did not change with the mid ordinate value.

It's good to know that it affects the spacing within a vertical curve.
