Batch Combined Points, Poly, Line and Annotation into .DWG

[MattReynolds1]

Please can somebody help!!  I have a huge amount of Ordnance Survey MasterMap Topo data which needs converting to DWG.  When I try and run the calculation for a large area (Sheffield District), the calculation is too large and crashes.  I therefore break this down by 1km map tiles to make the calculation smaller (use intersect and then split by feature).  I then convert these to DWG using a purpose built batch tool in model builder - Does anybody know how to batch process shp. to .dwg files? thanks to Robert Scheitlin, GISP.

The problem is, this only works for one geometry type; so one file for line, polygon and points.  Is there a way to batch these together?

Hi Matt,

When the crash occurs, what are you writing the output to (i.e .shapefile, File Geodatabase)?  If you are using a shapefile, there is a 2 GB limit.  Try writing the DWG to a feature class within a File Geodatabase.

Also, you may want to enable background processing so that 64-bit processing is used.  This may be able to process the large DWG file successfully.

Hi Jake,

thanks for the tips, I have tried both but it's still failing. I also changed the workspace to make it quicker but still the same. It's crashing after about 5 mins so quite soon into the calculation

How large is the DWG you are trying to convert?  (i.e. 500 Mb)

Matt,

What software are you using and what version (like ArcGIS Pro 1.4, ArcMap 10.5, etc.)?

Hi Adrian,

I'm afraid to say it's an old version; ArcMap 10.2.1, with standard licence configuration. 

cheers

Matt,

This should not make a difference but is there a way for you to upgrade to 10.3.1 or higher? I seem to recall having many issues with 10.2.1 and 10.2.2 regarding CAD data and crashing. It would also be good to know what your file size was for your CAD files (like Jake asked).

Adrian Welsh   and Jake Skinner  , many thanks.  What I am trying to do is convert feature data classes into a DWG.  The Line file is 380mb, the poly is 191mb, the point is 5.24mb and the annotation is 132.08.

What I have though, is a series of lines, points, polys and annotation which are all based on a respective Map Tile i.e. Maptile_001, Maptile_002 etc for each geomerty.  Is there a way i can combine those based on the common name of the Map Tile?

Matt,

That sounds like a pretty large amount of data and I am not sure how much a DWG can handle. I don't know if there is a 'compressed' version (like how there is a geodatabase instead of a shapefile, etc.). For combining, are you wanting to combine the DWGs after creating them? That would likely need to be done in AutoCAD, I would think.
