| Summary | 0001068: DXF export of "large" Polyline Curves | ||||
| Description | Pleases see screenshot. Upper window is how CamBam (CNC router path generator) interprets the exported DXF from the FreeCAD object in the lower image. The "DraftGeomUtils.isClockwise" fix got the curve in the right direction, but it almost seems like what is exported is the "missing" part of the ARC in the object. Do you need a check for arcs spanning more than Pi in the importDXF.getWire function? I will try to upload my FCStd file as well. Thanks for making FreeCAD happen, this is a really impressive tool. | ||||
| Additional Information | Tested on newest Ubuntu daily build. I am exporting DXF from simple object and loading into CamBam v0.9 CNC routing path generator for Windows. | ||||

Great. I uploaded dxf_export_2.jpg showing another part and the resulting import into my DXF "viewer". I'm not sure it was obvious in the previous jpg. But before the "isClockWise" fix the arcs at the bottom of the part would be the "other" way. I cannot help think that angle calculation might have been right to start with, only just the wrong part of the circle was exported.. or? |

Submitted a fix in commit 7556071 As far as I could test all works fine now. The problem was that arcs > 180 degrees were treated as < 180 degrees. I added a small function to correct that. I'm closing this issue now, please reopen if you still find wrong cases. |
