Feature Layer Editing lines with curves

WilliamKimrey — Fri, 01 Apr 2011 20:51:37 GMT

Hello all,

I have a line feature class that contains lines with curves made using the Arc Tool and/or the Tangent Tool to draw the initial geometries. I then have a web application that allows multiple users to edit the attributes of these lines.

I've noticed recently that the lines which contain curves are losing their curves after a user edits them. I have a suspicion that editing through the Feature Service doesn't allow for curved lines so it's creating a straight segment between the two points of the polyline, but I want to make sure that there's not something else that could be going wrong.

Any ideas or confirmation that you cannot in fact have curves in a FeatureService?

Thanks,
Will

Correct: Curves are not supported.

Thanks for the confirmation. I guess we'll adjust our data accordingly.

Is there any hope that curves would be supported in the future? Why haven't they been implemented so far in the first place? I'd be very surprised if I was the first person to mention this.

There are currently no plans on supporting curves.
We are looking into preventing the geometry from getting updated if you only edit the attributes, so you wont loose your curve.

OK, that would be a welcome change and would solve the issue that I'm currently facing.

Thanks for the info.
