Camera type bug

Hello,

I noticed a bug with Fusion returning wrong camera type when camera is set to PerspectiveWithOrthoFacesCameraType it returns PerspectiveCameraType.

Demo code used in the video:

#include <Core/CoreAll.h> #include <Fusion/FusionAll.h> #include <CAM/CAMAll.h> using namespace adsk::core; using namespace adsk::fusion; using namespace adsk::cam; Ptr<Application> app; Ptr<UserInterface> ui; extern "C" XI_EXPORT bool run(const char* context) { app = Application::get(); if (!app) return false; const auto cameraType = app->activeViewport()->camera()->cameraType(); auto type = ""; switch(cameraType) { case OrthographicCameraType: type = "OrthographicCameraType"; break; case PerspectiveCameraType: type = "PerspectiveCameraType"; break; case PerspectiveWithOrthoFacesCameraType: type = "PerspectiveWithOrthoFacesCameraType"; break; } app->userInterface()->messageBox(type, type); return true; }

Hi @rolandas_vegis .

I have experienced this before when I developed this add-in.

https://github.com/kantoku-code/Fusion360_PerspectiveAngleController

Wouldn't PerspektiveWithOrthoFacesCameraType return an OrthographicCameraType if the camera is parallel to the XY, YZ, or XZ plane?

Yes it does return OrthographicCameraType when camera is parallel to the XY, YZ, or XZ plane. Is this also a bug or is this expected behavior?

@rolandas_vegis .

I cannot determine if it is a bug or not.
However, it may be a bug since you even provide an enumerator.
