Hi,
\nRecently SpaceClaim starts to export DXF\/DWG in different way than before.
\nCircles (holes) in DXF have a parameter called “Z Normal”, it can be 1 or -1 (in our cases). Before latest version in the same exportation the Z Normal was 1 (or -1) for ALL circles. All circles had the same parameter.
\nNow, with latest release, it’s not the same. Some circles have “Z Normal = 1” and other “Z Normal = -1”.
\nThis causes in some software (for Example Bysoft from Bystronic, one of the most important sheetmetal laser producer) errors.<\/p>\n

I’m not an expert on AutoCAD and DXF\/DWG file structure, but\u00a0 this propriety is visible in AutoCAD.<\/p>\n

Here the external circle haz Z normal -1<\/p>\n

<\/p>\n

Here the internal circle has Z normal 1<\/p>\n

<\/p>\n

Result on Bysoft, the shape isn’t connected, seems Z-1 circles are mirrored<\/p>\n

<\/p>\n

Here the mirrored circles are visible, but sometime the risk is to produce part without some hole.<\/p>\n

Can you investigate with programmers?
\nThanks<\/p>\n","protected":false},"template":"","class_list":["post-254763","topic","type-topic","status-closed","hentry","topic-tag-import","topic-tag-spaceclaim"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
