Example .dxf file with Solid Hatch using lines and circles (not polyline)

Anonymous — Fri, 08 Mar 2019 08:49:49 GMT

I am working on a .dxf writer program adn I have to create Hatch with Solid fill using lines and circles in boundary path.
I was reading the documentation and forums, but I am not able to create a valid .dxf file, what the Autocad can open.
The generated .dxf is openable by LibreCAD and dwgSeePro.

Can somebody explain me how can create a valid .dxf / show a working example / explain the fails in my generated file?

Hi,

Start AutoCAD, draw what you want to test, run command _SAVEAS and change the filetype to DXF and give that file a filename ... that's your DXF-file you can analyze then.

>> explain the fails in my generated file?

We have no access to your generated file.

Dear Alfred,

Thanks for Your answer!

My biggest problem is with creating hatch, that the boundaries are polyline, when I create it with autocad. And I haven't find any example, where the boundary made with simple lines, arc's and cirlce.
So I attached my test file, what I can't open with Autocad, but I can open with LibreCAD.

Thanks for You answer and help!

Best regards, Adam

Sorry to not understand ... why searching for a sample when you can create it by yourself?

>> So I attached my test file

Nothing attached here.

Dear Alfred,

I have read the offical documentation and I understand the structure of dxf, and the basics of the hatch.
I get the data as lines and arcs. I can use them in the boundary path, what my code is create. And I wasn't able to creaty a valid hatch in this way until now.
SOrry, I did a fail. Now I attached it.

Find attached a test dxf with 3 lines (0,0 to 10,0 to 10,10 and close) and a hatch (ansi31, scale 0.1) based on ACADISO.DWT

Dear Alfred,

I don't find any dxf in attachement. And Your example is ANSI31, but I am using SOLID in my work.

Thanks for Your reply,

That's just a difference of the hatch pattern name, nothing else.
