I'm trying to set up some standard ORD DWG export processes for my organization and have only found a few methods to get the outputs I require without issues that require extensive post-processing to be good enough for delivery. Plan exports are a bit convoluted to get past the issue of elements exporting with no symbology after splitting strings with gaps during export, but it gets us close to what we want - unfortunately many issues regarding annotation values changing on export. Ideally i'd love us to be using Microstation to take advantage of the native dynamics, but unfortunately our market is primarily AutoCAD for drafting.
Here's what i've come up with so far using ORD 2018 R3;
*UPDATE* - A few improvements in ORD 2018 R4 meaning less custom processes
2D Alignment Plan export with Annotation - process required to export chainage annotation:
1. Open new DGN using 2D seed
2. Reference in Default model with no nesting
3. Turn off display of unnecessary levels
4. Create Fence around data
5. Deactivate Auto Field Update using "EXPAND SET MS_AUTO_UPDATE_FIELDS = NEVER" keyin
6. Use Fence to File command to copy contents to new DGN
7. Open New DGN
8. Select all Annotation Cells (named "DrawTextAnnotation") and drop
9. Select all Text Nodes and drop (this seems to allow correct export of field values)
10. Export to DWG
11. Reactivate Auto Field Update using "EXPAND SET MS_AUTO_UPDATE_FIELDS = ALWAYS" keyin
Note: You can start the process from your live DGN Default (2D) model and skip points 1 and 2 if you don't mind changing many level display settings in your live file. We keep a DGN saved for export levels already preset.
3D DWG Plan export - process required when model includes string gaps and clipping, etc.:
1. Open new DGN using 3D seed (or 2D for flattened DWG)
2. Reference in Default-3D model with no nesting
5. Use Fence to File command to copy contents to new DGN
6. Open New DGN
4. Select all Complex Chains and drop (required to avoid dropped chains being put on layer 0 by default)
5. Export to DWG
Note: If you want a 3d DWG and don't mind changing many level display settings in your live file, you can start the process from your live DGN Default-3D model and skip points 1 and 2. We keep a DGN saved for export levels already preset.
Cross section DWG export :
*Required DWG Export options:
Note: MS_REF_VISEDGE_ATTACH_STATE = CachedAutomatic config variable doesn't seem to be required anymore - correct me if im wrong?
Profile DWG export:
*Required DWG Export options:
I'm using ORD 2019 R1 and i'm trying to export a cross section sheet to DWG. I found that this would be the only way to export multiple CS into a single CAD drawing. Is this your workflow?
Anyway, i'm always getting an "error creating file" message. I have my export options set as you described above. Made sure no DWG file was attached in all my references. Set MS_REF_VISEDGE_ATTACH_STATE = CachedAutomatic. Still the same error...
Exporting the single cross section model works though. I have 13km of highway to provide cross sections for in DWG format. You can imagine that exporting them one by one would be unthinkable.
Any thoughts on what I should try next?
Yes, sheet models seem to be the only way to get multiple sections out currently. Maybe you could set up a very long sheet seed to get them all in one model?
Using the DWG export model filter (in your DWG Export settings), exclude the 2D and 3D design model and give it a shot. This should get it to export.
ORD 2019 R2 that is coming soon has many DWG export fixes and hopefully this is one of them. I'd put an SR in just in case so they can fix it.
Since I found that the only way to export multiple CS, I have a 5m sheet so I could fit the most that I can on a single sheet.
As for the filter, all I have selected is the sheet I want to export.. Same error.
I've sent a SR but haven't heard back from Bentley yet. I sure hope also that the next release will fix many of these DWG export bugs.
Thanks for your help.
I've found the same error trying to export DGN sheet models to DWG. I've followed the same steps as you did with no success. Did you manage to find a solution?
My workaround this, was to select in the filter only the CS models, in the general tab put Non-Default Design Models to "Create paper space" so that all CS are in the same DWG file. Set the References options as described by Mark above and then export.
Another workaround was to define "MS_AUTO_UPDATE_FIELDS" to "NEVER". In the sheet model, merge references. Restart ORD and export sheet only. Here's a video of this process https://www.youtube.com/watch?v=7tNjBUnPrFY
Hope this helps.
