Good morning,
Wondering if anyone else has come across this issue with the export tool built into Bentley Map?
I use the tool to create shapefiles to submit to our Environmental section, and also sometimes to create exhibits in ArcMap, but if the CAD alignment has curves in it, somewhere in the process of creating the shapefile, the curves are removed, leaving a straight line in between the begin and end of the curved alignment, edge of pavement, ROW, and any other lines that are curved within the CAD dgn.
I'm using this tool from Power GEOPAK. I first go to the GEOPAK menu and select "Activate Map". Then the File menu-->Export-->GIS Data Types...
From there, I create a new Export as a shapefile and select the file location. I select the layer that I am interested in exporting to a shapefile, and then Export. Before bringing it into an ArcMap map, I have to first view the file in ArcCatalog to set the appropriate coordinate system, as ArcGIS needs a coordinate system set in order to bring it into the map.
This is a snip of just the alignment and station tics. Any help given would be greatly appreciated!!
Thanks!
Stephanie
Stephanie,
Try setting the ECSDK_GEOMETRY_STROKING_TOLERANCE variable in your Workspace Configuration settings. The value used represents the maximum distance between the actual element and the approximating line in master units.
You can read more about the variable in the "Exporting CAD to GIS" section of the Bentley Map Help file, under the Interoperability topic.
Scratch that, don't the ECSDK variable. Use the Stoking Tolerance setting in the Topology Preferences instead. This setting produces better results in the resulting Shapefile.
Just tried the Topology idea on the bottom and it did not fix the curves for me.
Did you exit GEOPAK or the file, then open it again before using the Export command? If that doesn't work, please post your DGN File and we'll take a look.
Dan,
We've been testing the tool every so often ever since you and I tried many different things over the phone 2 1/2 years ago, to no avail. You mentioned it would be corrected in one of the service pack updates, but it is still an issue. Any updates on that?
Thanks,
Stephanie, the issue was resolved and is available in Bentley Map V8i (SELECTseries 4) v08.11.09.862 Update 8. GEOPAK plans to use this update in their next release.
See Item # 421446 in the Bentley Map V8i (SELECTseries 4) 08.11.09.862 - Update 8 Resolved Issues List. The ECSDK_... variable would then correctly control the amount of stroking for each arc that is exported.
