IFC text tree viewer

Hi Jon,

I'm probably missing something, but is there a reason that your IFC text tree viewer doesn't show all the entity instances in an IFC file?

As you'll see, only those in red here, were revealed in the tree. Screencapture here.

Curious too, why it only drills down to a certain level.

I'm probably missing something.

Hi Ryan,

Certainly there can be improvements to the tree browser. The primary premise has been to show the hierarchy and relationships from the ifc file root entry IfcProject (or also IfcProjectLibrary in IFC4).

There could be an option for a different mode to develop this tree from any arbitrary node as an improvement. This is possible in another viewer that I use, http://www.team-solutions.de/?page_id=19

For my browser I'd also like to add the ability to search (which can be done in quick browser above), also it's been suggested to modify an Ifc file (such as delete all entities not relevant to this node) to filter for testing.

If it's not drilling down all the properties, it's likely it's just not an attribute I have implemented yet. I could look at automating all children nodes using reflection, but at the moment they are manually created. I can post a newer build that has more as the public link is from some time ago.

Also seeing as this is posted in the grasshopper group, note that the tree viewer hosted in my rhino plugin also links to the geometric object in the rhino viewport (for at least the session when you've imported the Ifc). The objects selected in the tree also select in the rhino viewports as a means of highlighting /identifying.

Cheers,

Jon
