How to iterate and explode all polylines in modelspace?

[umli187]

Hello,

Is it possible to explode all polylines in .dxf document to lines and arcs?
I would like to do something like iteration over all polyline entities use explode(target_layout: BaseLayout = None) → EntityQuery and save result, Could you give me short example of code?

Thank you

Iterate POLYLINE entities in modelspace and explode them:

msp = doc.modelspace()
for entity in msp.query("POLYLINE"):
     entity.explode()

To do the same for LWPOLYLINE entities, replace "POLYLINE" by "LWPOLYLINE", to iterate both entity types use the query string:

"POLYLINE LWPOLYLINE"
