I changed camera settings to correct values but it was fruitless. I finally realized that there were four boxes whose Y positions were defined with formulas that evaluate the root square of.... negative numbers, the Y positions were therefore nan values . I then fixed the formulas and everything wen...

are you using a microsoft graphics driver or the one from the manufacturer of the graphics card? Here is what I see in device manager: Capture.PNG "Cartes graphiques" means graphic cards. I don't know how I should understand that information. I checked the drivers for both and they both f...

thomas-neemann : I'm using FreeCAD 0.20 on a Windows 10 PC jeno : as instructed in the link you sent I was able to locate the GuiDocument.xml file and here is what I found regarding the camera settings: <Camera settings="OrthographicCamera {&#10; viewportMapping ADJUST_CAMERA&#10; posi...

Thanks @chrisb for your reply. I just tried your solution but it made the situation worse: everything disappears and the viewport freezes, no way to rotate or zoom

Hello everybody, I am running into quite a similar issue. It is not that everything disappeared, but I don't see about half to all the objects in the viewport depending on the view angle. In some view angles everything disappeared while when I rotate to others only parts of the objects are visible. ...

Were the foraminate function to consider semi-infinite rays (that is, rays that originate from a point towards the direction indicated by a vector), neither of the situations described in the figure would yield intersection points. What I understand is that foraminate considers any ray as infinite r...

Hello, Thank you very much wmayer for your so instructive reply. I did implement the filtering work-around solution you sent and it did work. However, that let me realize a behavior of the foraminate function that can be undesirable to some (including me, especially in the problem I am dealing with ...

Thank you Carlo for your reply. Indeed, as shown in the quote below, wmayer did alter the Mesh.nearestFacetOnRay method, a change that is already available in the latest release of FreeCAD. a6f0f69ed6 With import math val1 = myMesh.nearestFacetOnRay((0.75, 0.25, 0.1), (0.0, +1.0, 0.0), math.pi/2) va...

Dear all, While this issue is "SOLVED", I am actually interested in something similar that can be solved by the workaround given by wmayer . I am interested in the Mesh.foraminate function, which in the official release of FreeCAD does only accept two parameters: an origin point and the di...

Hi! I understand now that I wasn't looking at the right documentObserver class. I updated the way you mentioned in your example and indeed everything worked fine now. Thank you very much for your help and for your explanations. My problem is solved. Please, I have one little question though, it is o...
