Summary | 0001727: API function Drawing.projectToDXF | ||||
Description | The API function Drawing.projectToDXF error generates the error: "Exception: Unknown C++ exception" And the script stops on this error. This is a regression compare to FreeCAD 0.13. | ||||
Steps To Reproduce | Run the attached script. This is a simple code that generates the bug. | ||||
Additional Information | The attached script provides the following output: FreeCAD 0.15, Libs: 0.15R3904 (Git) Test case for the Drawing.projectToDXF() bug Traceback (most recent call last): File "bug_drawing_projectToDXF_small.py", line 33, in <module> r_dxf = Drawing.projectToDXF(l_slice, vec_z_unit) Exception: Unknown C++ exception | ||||

The problem is not the dxf projection itself (try projecting the mybox1 object in your script) but the fact that recent OpenCasCade versions seem unable to project shapes that don't contain faces anymore, like the shape you are trying to project. This is a known OCC bug, we saw it appear many times already... I hope they fix it soon... BTW, the projectToDxf function has changed, it doesn't produce a DXF header anymore (so you can add more than one shape to a dxf file). You now need to add a header yourself, but it's not much work: dxfcode = "0\n0\nSECTION\n2\nENTITIES\n" + Drawing.projectToDXF(myshape,myvector) + "0\nENDSEC\n0\nEOF" |
