Let me throw this idea out there...
 
With your take lanes exposed/expanded, use the comping feature to select only the take (or takes) you want.  First, select the track containing the desired take(s) (with entire track high-lighted) and mute all clips (not track) in the track you wish to export the take(s) from.  Select the desired take(s) and make sure everything else is not selected (automatically muted).  The "composite" track (the main audio track) now contains the take(s) you desire in an isolated state at the same position as recorded.  Now prepare your export mix by muting all other tracks and soloing the desired (composite) track.  You will now have the specific take at its original position (with desired fx applied:  disable fx in mix down options or at the track level) for export. 
 
Of course, you would have to repeat this for each track which holds your desired take(s).  Try this and get back to us on your results.  Here is the comping video by the Bakers for your convenience:  http://www.youtube.com/watch?v=TPi1BkBhEvE&feature=youtu.be

What you're describing sounds like just exporting a comped track. That's not going to give you a separate file for each take with a single export operation, which is the goal of an "Export Takes" function.

This is exactly what I am doing now. Yes it works.  But it is extremely tedious when you have many tracks each with several takes.

What if you mix down to separate tracks?  Then export the new tracks at once.

What about selecting all takes, and just dragging them out to a folder? 

 
Good idea.  I tried this. It works well for takes that start at the beginning of a song.  But if you have takes that are just parts of a song (e.g., a vocal chorus, or a solo) then each file is only the length of the the specific clip so it would be very difficult for a mix engineer to line everything up.  Also, the caveats you mentioned are substantial.  Still, for some takes this approach is useful as a workaround.
 
While various work arounds may exist, this does not IMHO negate the need for Cakewalk to update the Export Audio feature.  With X3's take lanes now far more useful, takes have in many ways become the new tracks.  We need the Export Audio feature, will all of its flexibility, available for takes to use Sonar effectively for professional collaboration.

In Sonar 7 there is an option under Global Options/Audio Data for "Export Broadcast Waves By Default". Not sure if Sonar X3 has that option or where it would be located or if it would timestamp files exported by drag and drop. But you may want to try to see if there is something like that and if it does in fact time stamp the exported wave files by drag and drop. If so, any program that accepts broadcast wave files should be able to import them into the correct time location on the time line.

That's what I mentioned earlier.
A broadcast wave is time stamped so that a clip/track that goes for 2 bars but starts at bar 52 would have the timing info in the exported wave to locate the clip after 52 bars of nothing, then play for 2 bars.

That allows you to line up all broadcast waves.
I think it's in Preferences/audio off the top of my head

Ya I knew what you were getting at Mudgel. But it seemed the op and others didn't pick up on it so I tried to reiterate what you were saying.

I just couldn't remember if this works for drag drop. But I think it does. Also, the other program needs to be able to import broadcast waves. If I remember correctly ProTools charges like $500 for this feature.

This will probably be a triple post. Stupid @&$ forum software!

Thanks for keeping at this. I had not thought about this in the context of drag and drop.  Unfortunately drag and drop does not appear to work with take lanes, unless someone can show me how to do this. I have always has hit-or-miss luck using drag and drop to copy files to a separate folder - sometimes it works great, sometime resulting in my dragging tracks all over the Sonar project.  There is probably some logic to this that I am missing.
 
For the record, this approach does work well for non-taked tracks.  So this is a convenient way to export broadcast wave files if you don't have takes.
 

While looking for workarounds to the export audio issue I discovered other potential tools, OMF and bundle files, share similar issues that make them ineffective for collaboration when takes are used.  I posted this in a separate thread and put in a feature request.

I encourage others who collaborate with other engineers to weigh in here and with feature requests to help Cakewalk address this significant issue.
 
 

I have tried my own idea (post #11) about using the comp feature (after muting clips in the track) then bouncing/mixdown to separate tracks and then exporting those tracks. When comping with the track's clips muted it pick ups only those desired clips in the composite track at their position in the track/project. It works, try it yourself. Perhaps a video would convince you?
