Project description
copyifc
使用示例
import ifcopenshell
from ifcopenshell.file import file
from copyifc.copyifc import IDCache
ifc_file1 = ifcopenshell.open("test.ifc")
ifc_to = file()
comb = IDCache(ifc_to)
ins = ifc_file1.by_type("ifcroot")[0] # 其他查询
ins_new = comb.recursion_copy(ins)
仅仅提供一个递归调用,复制传入的entity_instance以及该entity_instance 指向的其他entity_instance
通过原始文件的 globalid 映射目标文件中的entity_instance,防止重复复制。
同时在复制时修改globalid。
为何?
当我尝试使用ifcopenshell自带的add功能时,发现这么一个问题:
在复制不同的ifc文件中的部分对象到同一个ifc文件中去时,会出现一些显示异常。
通过分析,揣测是在复制过程中,部分globalid相同的entity_instance,被共用了,但其实两者可能不一样。
所以尝试自己通过递归手动复制来完成。
并且达到了自己的效果。
ifcopenshell 依赖
项目依赖于 aconda 中ifcopenshell 库,未曾在项目依赖中标注,因为pip 无法直接安装aconda的库.请自行安装.
