EXPLODE A BLOCK IN AUTOCAD CODE

add the location-dependent properties (for example the alignment station) to the objects inside the block.

I thought I figured out a workaround, but there is an issue. import clrįrom import *Īdoc = Īdoc.SendStringToExecute('EXPLODE ', True, False, False) This will just select the objects and run the normal EXPLODE command at the command line.

EXPLODE A BLOCK IN AUTOCAD CODE

Here’s some Python code you can use as a workaround to the Object.Explode node. In other words, you haven’t changed the block definition by exploding one of its block references, you’ve basically just duplicated it’s contents into model space. When the block reference is exploded, the original elements within the block definition still need to be there, so what is really happening is that entirely new objects are being created. It’s not that the Object IDs of the objects within the block definition are changing after you explode, it’s that they are entirely different objects. Yes, although I would maybe state this a little differently. dwg files inserted in the revit file although frankly I have not explored much this last one.īuena suerte Amigo I had the idea of referencing the Object ID, but I didn’t realize that the Object ID changes after exploding and I again have no reference on which object I need to apply the data.

The package Genius Locky has some nodes that allow to read the information inside.

GitHub - Autodesk/civilconnection: CivilConnection enables the exchange of information between Civil 3D, Dynamo and Revit.

The package Civil Conection works for revit and allows you to connect Civil and Autocad files and do Querys in real time let’s say directly in Dynamo for Revit (it is difficult to install this package and you have to use the same year version of Revit and C3D) and maybe in revit there is an efficient way to export to IFC files, revit is a product of methodology BIM.

The package Camber has several nodes of type external documents, so you can do the query in a document where the blocks are and insert solids with their information in another, although honestly I’m not sure if in C3D there is an easy way to export to IFC formats especially because what you are trying to do is of the bim methodology maybe someone else in the forum knows, besides maybe that’s the right question to ask.

Hoo, i see very particular workflow, may be you can explore other options, I’ll give you some ideas, maybe some of them will work for you: I didn’t want to mention all this since it is pretty complicated but I guess it’s necessary to understand the issue at hand. But then the “identifying properties” get lost in the process. The workflow I planned to execute this was to explode the block references and then apply the “placement dependent properties” on the exploded solids. Exactly this station would become the value of one of the placement dependent properties. In practice I would for example place the signpost multiple times along an alignment at specific stations. Those properties are dependent on where I placed the block. Properties outside (automatically) applied after the block reference has been placed using dynamo. For the foundation I would use the identifier “foundation”, for the signpost “signpost”.Ģ. For example I would create a block and model a signpost with a foundation. In practice these properties are simply identifiers for the objects inside the block reference.

Those are the properties that get lost when using the explode node in dynamo. Properties inside the block (manually) applied to the individual geometry. there are two kinds of properties that I apply:ġ.→ an argument could be to just apply the properties after exploding the block references, but there is reason number 2.
