Write Pset and Qset via python code

1. V by valgianf on 19 Feb 2024, edited 19 Feb 2024 #

   Hi everyone,

   I'm trying to write custom pset and qto set via python code. For now I've tried to follow this instruction https://wiki.osarch.org/index.php?title=BlenderBIM_Add-on/BlenderBIM_Add-on_code_examples but it doesn't work and I don't know why. Would someone be able to help me with this issue? I really appreciate any help you can provide.

   Below there is the code I texted:

   ====================================================

   import bpy

   import numpy as np

   import os

   import ifcopenshell

   from ifcopenshell.api import run

   import ifcopenshell.api.owner.settings

   =====================================================

   Create BIM project

   createProject = True

   if createProject:

   bpy.ops.bim.create_project()
   
   bpy.context.scene.BIMProjectProperties.author_name = "Valerio Gianforte"
   
   bpy.context.scene.BIMProjectProperties.organisation_name = "LIam"

   Create Object

   addCube = True

   if addCube:

   cube = bpy.ops.mesh.primitive_cube_add()
   
   bpy.context.scene.BIMProjectProperties.ifc_product = "IfcElement"
   
   bpy.context.scene.BIMProjectProperties.ifc_class = "IfcCivilElement"
   
   bpy.ops.bim.assign_class(ifc_class = "IfcCivilElement", 
   
                           predefined_type = "IfcCivilElementType", 
   
                           userdefined_type = "")
   
   bpy.data.objects["IfcCivilElement/Cube"].BIMTypeProperties.relating_type_class = "IfcCivilElementType"
   
   pset = bpy.context.active_object.BIMObjectProperties.psets.add()
   
   pset.name = "Pset_PackingInstruction"
   
   prop = pset.properties.add()
   
   prop.name = "AC_Pset_RenovationAndPhasing"
   
   prop.string_value = "Costo della struttura"    

   I'd like to obtain a situation like the following image:

   @valgianf hi, i suggest you to use the API as explained here:

   https://blenderbim.org/docs-python/autoapi/ifcopenshell/api/pset/index.html

   I'm not sure if those code examples are still valid because i don't find bpy.context.active_object.BIMObjectProperties.psets.add() for example ...

   Hi @Massimo thank you for the tip but I think that API doesn't work for my aims because if I don't understand badly, the API is applied to parse IFC file. In this case, I have not an IFC file but I would like to give my object custom properties as shown in the image above via Python. Another question could be if it is possible to import via Python a pset template written as a CSV file.

   @valgianf you are welcome :-)

   PS. Looks like you are italian ... if you are interested, there is a post for you https://community.osarch.org/discussion/1918/

   @valgianf well, you can use API for many things, also for create a new model for example (look at https://blenderbim.org/docs-python/ifcopenshell-python/code_examples.html#create-a-simple-model-from-scratch).

   For your aims i think you can use this

   https://blenderbim.org/docs-python/autoapi/ifcopenshell/api/pset/add_pset/index.html

   The API works directly to the ifc file (simple speaking) instead of work thought the blender application (sorry for maybe not precise technical language ...)

   For your second question the answer is yes but you need to "work a little" :-) ... you can look at this video btw

   It is not explained directly how to do your job, but you could first export the pset, modify the .csv file and then reimport ...
