error: entity references itself
error: entity references itself
i have an exporting problem now:
i export a line and a dimension to a dwg file. if the drawing exported as 2000 and the before version file, there throws an expection: error: entity references itself. but when exported as 2004, there has no error. now the dwgdirect library i use is 1.10(update 1). but when i used dwgdirect 1.09, there has no this error under the same case. i don't know what causes this.
there attachment file attach.zip contains two files: r2000.dxf is the file when exported as 2000, and r2004.dxf is the file when exported as 2004.
