Summary | 0002168: Arch Section plane cut view: invisible sketcher symbols | ||||
Description | When editing sketches and there are revolution features present, it is often handy to cut those revolutions so that they don't obscure parts of the sketch. However, when doing so, sketcher points and constraint symbols (not text) become invisible. I am aware that sketcher stuff, when editing, is slightly raised, so I tried raising the section plane by 10mm, but it doesn't help. What does help is viewing the sketch at an angle (even a small angle is often enough). | ||||
Steps To Reproduce | Steps: 1. open attachment section-sketch-nosymbols.FCStd 2. (if below 0.16.5117) Select Section, and toggle Cut View property off and on to enable slicing. (was another bug, fixed by yorik) 3. Edit Sketch. Points are not rendered. Most of the constraints are not rendered. Only distance constraints, and all the edges are visible. | ||||
Additional Information | Even though points are not displayed, they can be selected (remaining invisible) and dragged with mouse. Rotating the view a bit so that the sketch is viewed at an angle makes the invisible stuff appear. forum thread: http://forum.freecadweb.org/viewtopic.php?f=3&t=11486 OS: Windows 8.1 Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.16.5112 +17 (Git) Build type: Release Branch: (detached from abdullah/solver_control_information_5) Hash: dc7dc09fb53010bb1b3129061b1a21f5e43fc7e7 Python version: 2.7.8 Qt version: 4.8.6 Coin version: 4.0.0a OCC version: 6.7.1 | ||||

@looo the remaining issue here is pivy related. Since you've forked it, care to take a look? |
|
I think this is related to markers of coin. I can reproduce the problem with pivy markers and a minimal clipping plane. There is a plane cutting, but somehow it is not at a correct height. In my eyes a cutting plane should never effect a sketch and therefore for a sketch a cutting plane should be disabled. This is definetly possible with opengl. (glEnable(GL_CLIP_PLANE0)) A nice implementation would be a coin node which can be placed infront of the sketch main seperator to stop the clipping algorythm. FreeCAD objects should define a clipping mode-> solid clipping, normal clipping, no clipping) and place a clipping node infront of the specific scene. Some ideas can be found here: ( https://forum.freecadweb.org/viewtopic.php?f=8&t=18188&hilit=clipping+plane&start=10#p170918 In my eyes this is another problem of FreeCAD which is not yet solved, but should be possible with some amount of work. |

closing. Although the bug is still there, Sketcher now offers a clipping plane that overcomes this bug. |
