getting, setting, changing the camera view
Hello,
You could change the attributes of "Camera" to change model position in Viewport. I attached a sample script as below for your reference. Please create a new Python script and copy the following codes to that script to have a try.
Thanks,
Marshal

import adsk.core, adsk.fusion, traceback
def main():
ui = None
try:
app = adsk.core.Application.get()
camera = app.activeViewport.camera
camera.viewOrientation = adsk.core.ViewOrientations.FrontViewOrientation
camera.isFitView = True
app.activeViewport.camera = camera
except:
if ui:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
main()

Hello,
It could be difficult to tell what camera attributes should be given for "arbitrary" view. A proposal would be as below:
1. Set view to what you want in UI.
2. Run the following script to get the attributes of camera.
3. Set those values to camera by the previous script codes.
Thanks,
Marshal

import adsk.core, adsk.fusion, traceback
def main():
ui = None
try:
app = adsk.core.Application.get()
ui = app.userInterface
camera = app.activeViewport.camera
eye = camera.eye
target = camera.target
upvector = camera.upVector
ui.messageBox('Eye: {0}, {1}, {2} target: {3}, {4}, {5} upvector: {6}, {7}, {8}'.format(eye.x, eye.y, eye.z, target.x, target.y, target.z, upvector.x, upvector.y, upvector.z))
except:
if ui:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
main()

What you have is good. You're just missing a viewPort.refresh() call after you set the camera.
Unfortunately, I've identified a problem where when setting the camera of a viewport the up vector is being ignored. I've reported the problem and expect it to be fixed in a future version.
Where's what I was playing with. Python is new to me too so there is probably a more direct way of accomplishing some of this, but it does seem to work. The script below captures the current view information and saves it to a file.
import adsk.core, adsk.fusion, traceback, ast
def main():
ui = None
try:
app = adsk.core.Application.get()
ui = app.userInterface
view = app.activeViewport
cam = view.camera
eye = cam.eye
target = cam.target
up = cam.upVector
if cam.cameraType != adsk.core.CameraTypes.OrthographicCameraType:
perspAngle = cam.perspectiveAngle
else:
perspAngle = 0
cameraData = dict(eye=str(eye.x) + ',' + str(eye.y) + ',' + str(eye.z),
target=str(target.x) + ',' + str(target.y) + ',' + str(target.z),
up=str(up.x) + ',' + str(up.y) + ',' + str(up.z),
cameraType=str(cam.cameraType),
perspectiveAngle=str(perspAngle))
f = open('c:\\temp\\Fusion360Camera.dat', 'w')
f.write(str(cameraData))
f.close()
ui.messageBox('Finished saving the view information.')
except:
if ui:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
main()
This next script then reads the file and applies it to the current active view port. This works except for the up vector issue.
import adsk.core, adsk.fusion, traceback, ast
def main():
ui = None
try:
app = adsk.core.Application.get()
ui = app.userInterface
f = open('c:\\temp\\Fusion360Camera.dat', 'r')
newCameraString = f.readlines()
newCamera = ast.literal_eval(newCameraString[0])
f.close()
newEyeString = newCamera['eye'].split(',')
newTargetString = newCamera['target'].split(',')
newUpVectorString = newCamera['up'].split(',')
newCameraTypeString = newCamera['cameraType']
newPerspectiveAngleString = newCamera['perspectiveAngle']
newEye = adsk.core.Point3D.create(float(newEyeString[0]), float(newEyeString[1]), float(newEyeString[2]))
newTarget = adsk.core.Point3D.create(float(newTargetString[0]), float(newTargetString[1]), float(newTargetString[2]))
newUp = adsk.core.Vector3D.create(float(newUpVectorString[0]), float(newUpVectorString[1]), float(newUpVectorString[2]))
newCameraType = int(newCameraTypeString)
if newCameraType != adsk.core.CameraTypes.OrthographicCameraType:
newPerspective = float(newPerspectiveAngleString)
view = app.activeViewport
cam = view.camera
cam.up = newUp
cam.eye = newEye
cam.target = newTarget
if newCameraType != cam.cameraType:
cam.cameraType = newCameraType
if newCameraType != adsk.core.CameraTypes.OrthographicCameraType:
cam.perspectiveAngle = newPerspective
cam.isFitView = True
cam.isSmoothTransition = True
view.camera = cam
view.refresh()
cam = view.camera
ui.messageBox('View restored.')
except:
if ui:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
main()
Hello,
I changed your codes a little bit and it seemed to work as expected.
--------------------
import adsk.core, adsk.fusion, traceback
def main():
ui = None
try:
app = adsk.core.Application.get()
camera = app.activeViewport.camera
#camera.viewOrientation = adsk.core.ViewOrientations.IsoTopLeftViewOrientation
eye = camera.eye
eye.x = -28.61
eye.y = 13.98
eye.z = -28.74
camera.eye = eye
target = camera.target
target.x = 0.0
target.y = -7.23
target.z = -1.23
camera.target = target
upVector = camera.upVector
upVector.x = 0.34
upVector.y = 0.88
upVector.z = 0.33
camera.upVector = upVector
#camera.isFitView == True
camera.isSmoothTransition = True
app.activeViewport.camera = camera
app.activeViewport.fit()
except:
if ui:
ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
main()

Hello,
I gave a try to Brian's codes and didn't see the crash. Did you send crash report? If yes, please tell me the report number which display in web page after you send the report. Or please tell me your email address which you filled in Autodesk Error Report dialog. I can check what could be the problem?
Thanks,
