Attribute value disappears when synchronise ArcGIS for AutoCAD

Anonymous — Fri, 14 Feb 2020 11:56:05 GMT

Hi. I am quite new to AutoCAD. I am using ArcGIS for AutoCAD plugin. It works great for moving features in AutoCAD and synchronising changes back to our ArcGIS Enterprise server. However, when I synchronise, all of the attribute values in my blocks disappear. Is there a way to keep the defined attribute values within the block when I synchronise? Otherwise I have to manually enter values each time I synchronise, which is extremely frustrating.

Additionally, is there some way to link the rotation of the block with a value in the attribute field of the ArcGIS feature layer? Thank you

You are confusing an AutoCAD block attribute with ‘attribute data’ as in a database.

The value (and purpose) of an AutoCad block is ‘reusable content.’ You can have multiple instances of a block where each block’s attribute varies from instance-to-instance, hence reusable content. The attribute is held in the block itself. (Think scale bar block reused from viewport to viewport.)

in ArcGIS attribute data is held in a separate file, the dbf. In your uploaded images, the third image indicates there’s no attribute, it’s null, it’s not carrying over to ArcGIS. On top of that, it needs to find a relationship between that particular attribute value with that particular block symbol. That’s a lot to ask from Vanilla Acad.

I don’t know of a way to move the individual Acad block attributes into your database using Plain Vanilla AutoCad. I don’t know of a way using the ArcGIS plugin either. If you use Map 3D though, it’s entirely possible even without using the plugin. Map 3D can create, read and modify shapefiles.

Hi,

Thanks for getting back to me. I'm not sure I follow. My main issue at the moment is that when I synchronise changes, all of my block attribute values disappear. I.e. each lighting symbol needs a number label next to it. When I sync, the numbers disappear. Is there a way to fix the numbers? These don't necessarily need to sync to ArcGIS, I just don't want them to keep disappearing in AutoCAD.

Thanks

Georgia

Try ATTSYNC command, be sure to follow the instructions on your command line.

So the lighting symbol is a block, correct? Would it be possible to upload a copy of your block?

Looks like I'm a bit late here but had something similar happen. The block attributes get defined and are populated in GIS, then the block is synchronized to update the CAD dwg. At that time, it seemed the values were all deleted when reviewing the esri sync window. I discard all edits, the blocks redraw and the field value from GIS shows for a quick second then disappear again. I'm not sure how to resolve that yet, but just noticed opening up a drawing with a project area set up the esri features seemed to be gone, so I try the sync, after review it's trying to delete all features. Discard the edits and they are back in which solved that issue.
