Looking for some workflow ideas in Rhino, as well as custom Python scripting to make this work efficiently. 3 KB. Using blocks lets you keep model size smaller by using block instances instead of copying identical Block Instance Info. // Set the box material to "Use Object Parent". Now you can create block definitions with object attributes and bake them directly into your model. Ideally you should be able to deconstruct any VisualARQ object into basic primitives like geometry, styles names, property values and reconstruct it back in Revit as native elements but there are still missing parts on both sides to do a workflow like that. Hello, I’m working on a Display Conduit script in Python 3 that works for block instances as well. (I can open it, but it behaves weard - shading mode is displayed wrong and Object names are stored in the Rhino 3DM file and exported to file formats that accept object names.

Group everything in that block with the work point. Edit the position, rotation, and scale values of the block instance. My grasp on how blocks work in Rhino is a bit tenuous, you're probably better off asking pure RhinoCommon questions on the discourse forum. As a user you can use NonManifoldMerge followed by CreateRegions (see comments by @chuck in the posts). If a nested instance is to be edited while BlockEdit is running, it must be chosen from the dialog; it cannot just be selected from the graphics window, nor can a another _BlockEdit be started while a BlockEdit is I hope to get a constructive, but specific, discussion going about where we are with regards to automating Title Blocks. The initialization of the instance variable can be done directly but there can be performed extra operations while initializing the instance variable in the instance initializer block. Place a point like an insertion point on to the block. Once this object is in a block it will receive the material that is assigned to the block instance. When inserting a file with the Insert command, the file's ModelBasepoint will determine how the geometry is being located I know this is an old thread but here is a simple script to select similar blocks, using the method Jarek suggested with pre-select accepted : Sub SelectSimilar() Dim strObject, StrName strObject = Do you pick a single object first to set the filter to a specific block instance? Maybe follow Rhino logic. Edit. Maybe I can’t see the trees for the forest here - Is there a way to pick a block and simply swap it for a different one?

Unable to paste, no Rhino objects or text on the clipboard. Otherwise I would have to explode a copy of the instance and then pick it, right? Or is there an easier way? Thanks, T. Hi @stephenlog, we currently are only sending DirectShape geometry as meshes from Revit, and so when receiving them in Rhino you are getting Blocks containing meshes. 2. AllInstanceDefinitions How exactly do I get the position of a block instance object, which doesn’t contain any geometry in itself and holds other sub-objects ? This happens especially with block instances. Edit one of them so they all got edited. I would prefer to use reference style layers for non-embedded blocks but have hit a problem - I can’t delete an unwanted layer even if I no longer use the block. The block instance will refer to the new block definition. It is already possible to hide layers however often you need a more granular control over individual objects.
