Block.Extents null Value

I am trying to create a polyline around AutoCAD blocks in model space to then manipulate a layout and help auto create a fence line around a project site. I have setup a graph to allow a user to select block references in model space and then it filters through the names of selected block references vs the blocks in the database, then I am attempting to use the Block.Extents node to get a bounding box around the AutoCAD blocks. For some reason 2 of the 6 AutoCAD block references are returning a null value as you can see in the below screenshot. Thoughts on why this is happening? I have confirmed these blocks are active in model space and have geometry associated with them. DYN and DWG files attached, as well.

Hi @jbrunkhorst,

I noticed that within those block definitions there are several invalid 3D solids with zero volume. If you clear those out, then it behaves as expected.

However, this should be handled properly by the node. I’ll add it to our backlog to investigate.

@zachri.jensen You rock! That fixed it, thank you!
