| Summary | 0001287: Loosing Snap when Object is getting more complex. | ||||
| Description | Hi Yorik! (This is my first report ever, so be kind) Windows Vista 64, Windows 7 Version: 0.13.1828 Python version: 2.6.2 Python Command Line says 3.3.2 Qt version: 4.5.2 Coin version: 3.1.0 SoQt version: 1.4.1 OCC version: 6.3.0 <-Here I explain my Workflow for the case I'm doing something wrong. < <It is like this: Every part I work on is mainly something like a box, and I <found out that is very comfortable to layout the projections for the sketches <in 2d cad around (0,0), before I start freecad. So I dont have to use any <constraints, the sketches just jump in 3d to the right place. <Then I turn each 2d part which has the same depth into a block, projecting as <one sketch on the main volume and cutting them out (most efficient for me), <champfering and filleting when the part is done. After that, I only work with <copied solids and try to fuse as many parts together as possible with the <openscad workbench. I'm only doing so because I want to move as less objects <as possible in 3d space and the lines are hidden when I use the project 2d <button. The Main Point: Draw a line, Move/Rotate, Dimensoning a Part (all Draft Tools witch depend on coordinates) are not working anymore when i finish some of the parts. The funny thing is that Preselect still perfectly shows Vertex Positions in Yellow. (I use it for 'Incremential' movement which is the only possible placement method for me right now, without snapping) When I hover above some parts the preselection is fine (yellow lines,planes etc) but the big black points for the fine draft snaps are missing. When the preselection grabs I got these errors (all the same): ------------------------------------------------------------ Active document is Chair (at 0A43ED38) Pick first point: <type 'exceptions.TypeError'> Traceback (most recent call last): File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftTools.py", line 483, in action self.point,ctrlPoint,info = getPoint(self,arg) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftTools.py", line 144, in getPoint point = FreeCADGui.Snapper.snap(args["Position"],lastpoint=last,active=amod,constrain=cmod) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftSnap.py", line 191, in snap point,eline = self.snapToExtensions(point,lastpoint,constrain,eline) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftSnap.py", line 386, in snapToExtensions if isinstance(e.Curve,Part.Line): TypeError: undefined curve type <type 'exceptions.TypeError'> Traceback (most recent call last): File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftTools.py", line 483, in action self.point,ctrlPoint,info = getPoint(self,arg) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftTools.py", line 144, in getPoint point = FreeCADGui.Snapper.snap(args["Position"],lastpoint=last,active=amod,constrain=cmod) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftSnap.py", line 191, in snap point,eline = self.snapToExtensions(point,lastpoint,constrain,eline) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftSnap.py", line 386, in snapToExtensions if isinstance(e.Curve,Part.Line): TypeError: undefined curve type <type 'exceptions.TypeError'> Traceback (most recent call last): File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftTools.py", line 483, in action self.point,ctrlPoint,info = getPoint(self,arg) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftTools.py", line 144, in getPoint point = FreeCADGui.Snapper.snap(args["Position"],lastpoint=last,active=amod,constrain=cmod) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftSnap.py", line 191, in snap point,eline = self.snapToExtensions(point,lastpoint,constrain,eline) File "C:\Program Files (x86)\FreeCAD0.13\Mod\Draft\DraftSnap.py", line 386, in snapToExtensions if isinstance(e.Curve,Part.Line): TypeError: undefined curve type <type 'exceptions.TypeError'> --------------------------------------------------------------- After that I can not draw anything by clicking in the main view. No Snap at all. Some computers I can revive draft snap by open a new document, at mine by restarting freecad. But as soon I hover even small and not so complex objects with this error its gone. While really using it for for work I found out, it is the best to turn off 'Always snap to objects' not to loose snap accidentally, and just use snap when i need it. Does somebody have a good idea? | ||||
| Additional Information | Maybe 'Jürgen Kilb' (earlyer post) had a similar problem while moving the spheres. | ||||

Hm it looks like some of your objects contain edges of an unknown type... I have never seen this before. Could you attach one of those objects here so I can have a look? |

Update: I finally managed to upload an example Object. |
|
|
Okay I see... Indeed there is some weird edge there, that screws the snap system (and consequently all draft commands after it). I'll try to fix this ASAP. In the meantime, FYI, if you press escape when the problem appears, it resets the snapping system, and things should continue to work normally after. |
|
|
At the Computers I tested on, Escape does not work, I have to reopen the document or open a new one. It still works to type in the coordinates in the draft bar after the errors. maybe there is a command for reset I could try. Anyway right now I use placement tool as workaround, and make the drafts in another document. it works quite well. Thank you for taking a look onto this. Niklas |

Ok this is now fixed in the current source code, you might need to wait a bit until someone builds a new windows package, though... Fixed with commit 7249ee |
