Get all entities considering xclip-clipping area

[cococosusu]

Hi!

I have been using the features of the recently released version 1.3.0 and they are very helpful.
Thank you.

I have a question regarding the existing recursive_decompose function.
When using this function, all entities are decomposed recursively, but as mentioned in the documentation, the clipping paths of xclip are not considered.

So, my question is:
How should I approach applying clipping paths to the decomposed entities?

I would appreciate any ideas you might have.

Thank you in advance ;)

Sorry, I can't help - it just don't work.

There is a way to explode clipped block references.

It is not possible to clip arbitrary DXF entities with ezdxf but it is possible by using the drawing add-on and the DXFBackend.
This process converts all entities inside the clipped block reference into drawing primitives. The clipping path is applied to the drawing primitives and the result is exported as DXF entities.

These new DXF entities are not related to the input entities! The layer is preserved but everything else is lost e.g. dashed lines will be exploded into short solid lines, similar to importing PDF files.

import ezdxf
from ezdxf import xclip
from ezdxf.addons.drawing import Frontend, RenderContext, dxf


def main():
    doc = ezdxf.readfile("xclip.dxf")
    msp = doc.modelspace()
    backend = dxf.DXFBackend(msp)  # target layout msp could be a new BLOCK
    frontend = Frontend(RenderContext(doc), backend)
    for insert in msp.query("INSERT"):
        if xclip.XClip(insert).is_clipping_enabled:  
            frontend.draw_entities([insert])
            insert.destroy()
    doc.saveas("exploded.dxf")


if __name__ == "__main__":
    main()

input file: xclip.zip

As an example the CIRCLE is converted to a POLYLINE:

OMG...it's so perfect!
This is exactly the result I was hoping for.

I understood what was said well, and I will refer to it and use it well!

Have a happy Friday :)
Thank you so much 👍
