Ecotect camera rotation problem

I am having issues related to setting up camera in Ecotect. Did anyone here have a problem with images getting rotated while visualizing through a wide angle camera?

Feel free to direct me to a more appropriate forum for Ecotect users. I just know of the Autodesk forum which is pretty inactive.

Thanks in advance,

Hi Shubha,

I do not have Ecotect here, but as far as I know, it makes useage of
Radiance. So if you are able to locate the view settings used when
rendering the view, you can check the camera settings. Usually the
extension of the view settings in Radiance is .vf, I would expect (or
hope) that Ecotect keeps this.

There should be a line inside the view file containing lots of
parameters starting with -v (all these are Radiance's view settings). If
there is a string "-vu X Y Z" (X Y Z being a vector) you can correct the
image alignment. The vector given here is the 3d vector in scene
coordinates that will point towards the upper edge of the 2d image.

In most perspective views and sections, it is -vu 0 0 1 (as +z points up
in the coordinate system used), while in a plan view with north being up
it should be -vu 0 1 0.

Hope this helps. I have no idea about Ecotect support.

Cheers, Lars.

Ecotect is pretty bad in the visualization view, especially if you have a
very detail model (or one that you imported from sketch up or Revit). I
always have issues with my model not looking the way it really is.
See the attached example of a library I'm working on.

Hey Shubha,

I have that issue sometimes. Check the default tab in the visualize mode. If
that view is in plan, the camera angles rotate. You need to keep that view
in perspective. Hope this helps.

Thank you all. Checking the default tab worked well.

When importing from Revit, line work is exaggerated in the visualization
tab as if it's weight is a diameter. That's what appears to be happening
in the images you've attached.

I always keep the imported geometry on a separate Zone and move the
critical parts of the model needed in Ecotect (which shouldn't include
line work) onto new zones. You can toggle the line work zones off when
in visualization.

Clunkly, but that's how Ecotect rolls with Revit.
