Hello,
While trying to read the arrowheads of dimensions I encountered some problems.
I have created various .dwg files just for testing purposes, each one has different arrowheads: You can find them inside the attached file test.zip. For example:
First, if there is an Oblique arrowhead the generated .json file is blank. I mean, the .json file is generated, but without any entities/tables. Adding the -v9 argument shows many errors.
Second, looking at the DXF reference, the left arrowhead and the right arrowhead handles should be stored within the associated DIMSTYLE, in the DIMBLK1 and DIMBLK2 fields, respectively. But they are empty every time, is this normal? (I could be wrong here, they might be stored only if an override is happening, but I'm not sure)
Thanks,
Dave
