Reading DXF-file with a Multileader block doesn't show the block

QCAD Professional

QCAD Version: 3.32.9

The DXF-file is programmatically created with Python using ezdxf the best Python library in the world for creating / changing DXF-files. It’s fully OpenSource and tries to be as close as possible to the “DXF standard”. It’s also a great place to learn a bit how DXF works.

To make things easier, I created a DXF template with different blocks and add them programmatically when needed. Opening this DXF files in BricsCad or AutoCad shows the intended drawing.

ezdxf also supports creating a multileader with a block attached to it. I’m using this as a BOM balloon which I add by adding a point where the leader starts and a point where the leader ends. Then the block is automatically attached by ezdxfwith the right DXF codes.

Opening the DXF in QCad however doesn’t show the BOM balloons but got a bunch of warnings on the console:

I have created a very basic DXF file with only the BOM balloon in it and attached it.

I can confirm that the MULTILEADER entity type is currently not supported by QCAD.

Thanks for the fast response! Any chance this will be supported in future versions of QCad?

I tried to manually move to a normal leader which is displayed, but the block seems to be exploded and not connected to the leader anymore.

my_template.dxf (1.2 MB)

But it shows the BOM balloon which already helps a lot.

Was a bit to fast because the normal leader is just what it is: a leader. So the block can be somewhat attached but is will stay disconnected. I have to use the MultiLeader unfortunately.

There are no plans currently for adding multi leader support in QCAD. This might change in the future if there is more interest for this.
