Importing objectscreated in Land Development Desktop

[Anonymous]

I am opening a surveyors Autodesk Land Development Desktop file. Some of the site info is contained in objects created by the software. Curve Data for example is not showing up in ArchiCAD and if the DWG is sent as a ACAD r-13 file the Blocks are exploded and are boxes with only a Title like "AecDbCurveText (Aecdraft)". What do I have to do to read these objects?

Check what happens when you open it in plain vanilla AutoCAD. Probably similar or the same.

AFAIR, the LDT like ADT creates objects that you need enablers for in order to read them into plain AutoCAD. Also, try with R12, that should break everything down to plain blocks.

The Surveyor has saved the DWG with AutoCAD 2000 and as a AutoCAD13 format. Both open in my AutoCAD R14 (Last copy of ACAD I owned before they said upgrade or die.... went to ArchiCAD and sooooo glad, thank you AutoDesk)
They both open. The 2000 file reports many aec things missing and only option to "Do not show Proxy Graphics". The r13 file gives options "Do not show proxy graphics" and "Show Proxy bounding box".

Yes, I have heard about needing enablers for reading LDD objects in plain AutoCAD. Which at this point I do not want to both with because I am trying to not have to rely on my AutoCAD for anything. I want to use only ArchiCAD. Is there an enabler reading these objects in ArchiCAD?

Opening the AutoCAD 2000 File with AC 8.1 the layers that the object are on, are contained in the layer settings box but there is no information on those layer.
Opening the AutoCAD R-13 File with AC 8.1 the layers that the object are on, are contained in the layer settings box. The bounding boxes (created in AutoCAD from exploded objects when saved-down to R-13 Format) show even if there layer is hidden, when the "root" layer for the object is shown. The bounding boxes "obey" the layer settings hide/show preferences only after something is modified in the layer settings dbx.

Still no info of course because ACAD did not convert info once saved in older version.

Anyone know how and if ArchiTerra reads or has an enabler for LDD?

The latest AutoCAD-versions don't need an object enabler to read these "proxy-objects" from the specialised Desktop-versions (Land & Mechanical & Architectural).

Proxy objects are like snapshots of the geometry that is generated by specialised objects: it's like having the 3D-model of a parametric GDL-object stored as polygons & points, without the actual script that created it: you only retain the end result.

You should ask the person who prepared these drawings to use the AECExplode (or similar) tools in Land Development Desktop prior to exporting, so at least all the geometry comes through. There is no way ArchiCAD will read these objects in their native form and certainly not when they passed through an older DWG-file verision, like r13.
