1).  It would be nice to be able to create a breakline where two different surface intersect.  For example when you have two different ditches cross each other.  If you were able to get that breakline you could then explode the surfaces and use the created breakline to merge them all togther.

2).  It would be nice to be able to snap to object in views such as surface slicer.

Thanks,

1) id you create a 0 contour on the isopach created by differencing 2 surfaces you get that line - agreed that is a few steps to create but it does work but it then needs to be re-elevated to one of the surfaces (drape or change elevation) to create the 3D line you are asking for - this would be a nice tool to have

2) TBC 5.1 allows snaps in cross section, slicer and template editor

Alan,

 I believe i have been wondering the same thing. Can you show that process in more detail that you noted in #1 please. I believe I could use this when bringing a road into a site where the corridor surfaces and site surfaces meet to give me the breaklines I need when I want to merge surfaces. Usually at this point I have a road coming in with ditches on the road and ditches on the site and when i merge surfaces it creates a few spots that don't coincide right.

Thanks,

The enclosed video is a canned example - however you will see the steps to find the "0" contour on the Isopach Surface which will follow the intersection of any two surfaces used for volume calculations - I then show how to Explode the Contour to create Linestrings from it and then how to Re Elevate those lines to one or both the source surfaces - now you have the line of Intersection of the two surfaces - you can add it to the source surface model(s) and make a composite model out of the two surfaces.-this is a very simple example and of course the real world is different - let me know if this helps your process or where the next bottleneck is.

It is hard to merge surfaces and get it right unless the two surfaces physically meet along a common daylight line (Like a Road Model through an Existing Terrain. Where they Cross (as in this example in the video) while you can find the common line (the 0 contour) you likely will have to do some added work to get where you need to get to. Using the Highest / Last or Finish into Original only goes so far.

Let me know if this helps

Thanks Alan,

I believe that will work for me. I will follow up next time I have to execute this operation.

Thanks!!
