| Summary | 0002235: Cannot mirror mirrored object (within Part Design) | ||||
| Description | Attempting to mirror an object that is the result of a prior mirror operation fails with: "No valid features in this document. Please create a subtractive or additive feature first". I would understand if only the new half would be mirrored, it being the last feature ... perhaps the tool needs to become more flexible regarding the scope it works on. Multitransform is no workaround, as attempting to do 2 mirrors, vertical and horizontal axis, will fail, claiming one feature would not intersect support. This leaves the Part workbench mirror tool, which means awkward workbench back and forth and extra fusion steps. | ||||
| Steps To Reproduce | * Create rectangle sketch. * Pad it. * Select result, try to apply "create a mirrored feature". | ||||

I don't think this is a bug. ===== Attempting to mirror an object that is the result of a prior mirror operation fails with: "No valid features in this document. Please create a subtractive or additive feature first". ... * Create rectangle sketch. * Pad it. * Select result, try to apply "create a mirrored feature". ===== Yes, if we use Part Design > Mirror tool on a Pad when that Pad is the only 3D object in the FreeCAD document, the tool fails. However, this is the expected FreeCAD bahavior because Part Design WB > Mirror only works on Features and not the whole 3D object. In this unique instance, Pad is the entire 3D object. |

Seen another way, the mirrored thing is the only feature. A feature that could be mirrored easily, when it touches the mirror plane, the new geometry thus having support. That would be useful behavior. Faking availability only to produce an error dialog is not. Note the other aspects of this issue: * Multitransform doesn't work right in this case. * There's no other mirror tool in the workbench that would fill the gap. * Switching workspaces is annoying and the Part workbench mirror doesn't care about keeping it one part. Isn't the later at the core of why the Part Design workbench even exists? |

@thor, this should have been discussed in the forum first, so please continue the discussion here: http://forum.freecadweb.org/viewtopic.php?f=3&t=14563 |

With FreeCAD Pull Request 818 this part will no longer be an issue:Multitransform is no workaround, as attempting to do 2 mirrors, vertical and horizontal axis, will fail, claiming one feature would not intersect support. and so thus MultiTransform should meet users' needs, resolving this bug. |
