dwghatch issue

[jcthomas]

Hello,

I encounter troubles by running dwghatch program on several files (i.e. DWG file in attachment).
Herebelow the error returned by the program, no resulting DWG file :

I do not understand what could be the source of the problem (The files come from AutoCad)
There are two layers : 0 and vision. If I erase the layer "Vision", the program succeeds in hatching the DWG and resulting DWG is what I expect.
Thank you in advance for your help !

Hi,
Don't know how you started dwghatch.

Opened the file in Qcad.
On Layer 0 is a boundary.
On Layer VISION is a Hatch.
Selecting all >> Hatch >> creates one extra hatch.
Pritty obvious you can't Hatch a Hatch.

For so far my insights.

Regards,
CVH

The dwghatch tool expects a drawing file which contains exclusively the outline to be hatched (lines, arcs, splines, polylines, etc.). The attached drawing "testHatch.dwg" contains already a hatch entity.

Thank you, I understand.
I will come back to the provider of the DWG file in order him to fill the "Vision" layer properly.
