Note to ewatch: I have had similar experiences with what is shown in Issue+06.png, but there are also several other issues going on here. There is a certain amount of time Sketcher Solver uses to compute the solution to the Sketch, and there is also a very different time elapsed (not by Solver) to display the results in the 3D window. Sketcher Solver does not report the processing time elapsed in displaying the revised model. Editing Sketch1 and changing the Vertical Distance Constraint from 27 to 28 breaks Sketch2 because of the known Link to External Geometry / numbering issue. ============== EDIT 2014-05-05: Using newer FreeCAD builds I am unable to reproduce the problem any more. Build info is posted below. |

I've had time to look into this in more depth and with the recent FreeCAD daily build am unable to reproduce this problem. More detailed notes follow: ================= "How to reproduce: * Open Sigma Pava.FCStd (SS 01) * Edit "Sketch 1" Result: Works OK for me. ================ "* Change datum of vertical dimension constraint from 27 to 28 (SS 02) * You can already see now that something went wrong," Result: the exclamation point in red symbol is displayed next to "Sketch2" in the tree view, indicating an error. ================ "* Close sketch * Edit "Sketch 2" Open Sketch2 to edit, then zoom in on the magenta Link to External Geometry line at the top. Doing this shows that the Link to External Geometry segment is not used as a reference buy any constraints, and instead a Sketcher line segment is used, as evidenced in image "Issue+04.png". This can also be seen in the attached image "20140504au". Initially I thought this was a modeling error, but closing Sketch2 without changing anything in Sketch2, saving the .fcstd file, and reopening the model in FreeCAD again "fixes" the model. The red exclamation point symbol no longer appears, and the constraint can be changed from 27mm to 28mm, or 30mm as shown in the attached image 20140505a_Mantis_1260. The model updates correctly and without error. I saved my FreeCAD file at this point; it is attached as "20140505au_Mantis_1260_28mm.fcstd" Confirmed yesterday 2014-05-04 using: OS: Ubuntu 12.04.4 LTS Platform: 32-bit Version: 0.14.3512 (Git) Branch: master Python version: 2.7.3 Qt version: 4.8.1 Coin version: 3.1.3 SoQt version: 1.5.0 OCC version: 6.7.0 Reconfirmed today 2014-05-05 using: OS: Ubuntu 12.04.4 LTS Platform: 32-bit Version: 0.14.3538 (Git) Branch: master Python version: 2.7.3 Qt version: 4.8.1 Coin version: 3.1.3 SoQt version: 1.5.0 OCC version: 6.7.0 ================ "* Select some line from the sketch ..." Selected the same arc, deleted it, did an undo. Result: Solver reports Fully constraind sketch. No conflicts or over-constraints. Done with the file OP uploaded and done with the file I uploaded today. ======================== "* Delete the line ... <SNIP> ... * Marvel at the modern art that FreeCAD has created." Result: unable to reproduce this beavior with the build I used yesterday or today. ================== "solver time shown is completely wrong" Note to ewatch: Solver only reports the time used to solve the model, not the time spent processing the file for graphics display, as previously mentioned. |

I can't reproduce this problem anymore. Is it still an issue? |

Opening Sigma+Pava.FCStd and first running the ForceRecompute macro shows there is an error in Sketch 2. Sketcher Solver reports that it is Over-constrained. Next I opened Sketch 1 and changed the Vertical Distance Constraint from 27 to 28 mm, and when FreeCAD updated after I closed Sketch 1, Sketch 2 was OK. I think the problem is in the model and not in FreeCAD itself. All 3 of my auto check and refine preferences are off.
