Acad Proxy Entity help

[BBP-Arch]

I'm running ACA11.

I've got a drawing I got from a Surveyor. The grade contours are Proxy Entities that in addition to the line itself, have numbers every so often that indicate the contour's elevation. That's all great. I now need to edit these to create my grading plan. When I explode the contour, it turns into a million tiny lines. Instead of picking all of these entities and turning them into a Pline (or Spline), I wonder if there is a way to convert it into a pline or spline autmatically? This could get VERY time consuming....

Thanks,

Scott

I would isolate all those little lines, use the pedit command, multiple option (select them all), then join option. It might take your computer a bit of time depending on the surface to go through all that data, but just take a coffee break!!!

In the future ask them to export their drawings to AutoCAD2010 which will convert all the Civil3D object to more usable blocks, not proxy objects.

I was trying to reproduce this issue at my end and was unable to get it. Hence I needed some clarification on the issue.

*What application is the Surveyor using? And in which format are the files being shared.

When doing some test I tried opening a Civil 3d file in AutoCAD Architecture after installing Object Enablers the contours come as a AECC_TIN_SURFACE  but on exploding they turn into polyline.    

Also as Mary suggested you could the surveyors to export dwg as AutoCAD objects converting them into polylines.

As of now as the lines are already exploded to tiny line the only way would be to convert these lines to polyline using pedit.

I had a similar question, but had not tried to explode the entity. To get the entity back to a usable closed polyline I right-clicked and SELECT SIMILAR then JOIN. The result for me is a continuous polyline identical to the proxy entity.
