I have a simple block containing a circle and an attribute definition. When trying to place block references at x,y coordinates specified in an Excel file, the inserted block references are stripped of the attribute. Has anyone else had this issue? When checking the Document.BlockByName node to see…

@zachri.jensen please use the other node BlockReference.ByCoordinateSystem, does it make any difference?

Hi @Paolo_Emilio_Serra1 , thanks for the quick reply. I tried using the CoordinateSystem.ByOrigin node instead of Point.ByCoordinates and then feeding that into BlockReference.ByCoordinateSystem. I got the same result - the block references have no attributes. [Capture]

@zachri.jensen @olsen Could you please share the Block Reference? also can you confirm that if you insert the block references manually the attributes are still there?

I believe you got the files from my coworker. For others who may be intereseted, here are some screenshots showing my problem. I was hoping this script would create my “ID-blokk” at 0,0,0, with the ID-attribute set to 44. However, it looses the attribute all together. [sc3]

This block was inserted the normal way, as you can see it has the attribute “ID” set to 999 [sc1]

This is the block that lost its attribute “ID”, placed in 0,0,0 by Dynamo [sc2]

The block that I was using was basically identical to the example posted by @olsen and I was experiencing the same results.

@zachri.jensen @olsen I had the chance to test it and yes, when you create the block reference you initially have the result of BlockReference.HasAttribute() equal to false, but as soon as you set the value everything works as expected and if you test the BlockReferences again they return true. [i…

Thanks @Paolo_Emilio_Serra1 . So what I’m seeing is that you either need to set attributes in Dynamo or run ATTSYNC after they’ve been placed. Is that correct? My original goal was to use Dynamo only for the initial placement of blocks in model space, and then set individual attributes values afterwa…
