| Steps To Reproduce | Start FreeCAD New document Select Part Design workbench Task-> create a body Task -> create sketch Select -> XY plane -> ok create a line (any two points) fix a length of line -> 1-line length = 10mm name = my_dist create a second line fix a length of line -> 2-line for length click expression icon Either: Type C Use down arrow to choose Constraints.my_dist = Segmentation fault (core dumped) or type Constraints.my_dist = Segmentation fault (core dumped) | ||||

Xref: https://forum.freecadweb.org/viewtopic.php?f=8&t=22322 NB: my (short) experience of FreeCAD is that it is not very stable generally. It may be something in my environment? |

No problem here. The crash reported might be due to an outdated version OS: Ubuntu 14.04.5 LTS Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.17.10993 (Git) Build type: None Branch: master Hash: bf5f3484f6f5506795b6e9b86288c75ab7357291 Python version: 2.7.6 Qt version: 4.8.6 Coin version: 4.0.0a OCC version: 7.1.0 |

I have downloaded the latest appimage from here: https://www.freecadweb.org/wiki/Download That is: https://github.com/FreeCAD/FreeCAD/releases/download/0.16/FreeCAD-0.16.6707.glibc2.17-x86_64.AppImage It seems to be an older version: OS: "openSUSE Leap 42.2" Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.16.6707 (Git) Build type: None Branch: releases/FreeCAD-0-16 Hash: 5465bc47c95db45e0be85dc0e2872419efadce0f Python version: 2.7.6 Qt version: 4.8.6 Coin version: 4.0.0a OCC version: 6.8.0.oce-0.17 However, it doesn't crash with these constraints, but doesn't update changed constraints. Also, contraints with an expression don't seem to work - eg =Constraints.my_dist+3 I have gone to github to get the development version: OS: "openSUSE Leap 42.2" Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.17.10600 (Git) Build type: None Branch: master Hash: 4d9169faf778e9716fc647fb3fcf46462b5d99a4 Python version: 2.7.6 Qt version: 4.8.6 Coin version: 4.0.0a OCC version: 7.1.0 (apparently still not quite up to date?) That does not crash. Constraint dependencies are updated when the parent constraint is updated. Does not parse =Constraint.my_dist+3 Am I supposed to use a spreadsheet for this (=Constraint.my_dist+3) instead? |

@eivindkvedalen do you mind weighing in on this? |
|
|
When you enter formulas in the Constraint dialog box, don't use the equal sign; write the expression directly. The equal sign is only used in the spreadsheet workbench to differentiate formulas from text/numbers. |
|
|
@eivindkvedalen isn't that how excel spreadsheet triggers the formula editor? If so, not to do that would be, in my mind, not very intuitive. |
