As an extra information, I have just found out that the file crash every time I try to open the site settings.

Also, In the perspective view I showed before where the shadows are wrong, If I turn off the planting category, the problem disappear.
So I assume the issues are with the massing/terrain/topo/planting.....

Hello,
I have created a template for Revit and few of the user are finding graphic issues with it.
I created for Revit 2017 but we mainly use Revit 2018 now.
We have create a model, place sun and everything else, and looks ok in the 3D view.

But then, when we create a 3d perspective view with the camera tool, shadows create a very weird shapes. You can see that the roof eaves produces a curve shadows or weird things.

In other case, using the same template in Revit 2017
We have created a detail using regions, lines and other annotation, and copy it in our company template (right) and in a default revit template (left), look at the differences marked in red circles, how the lines and regions are distorted.

My graphic card is a Radeon RX 470, and my pc is less than a year old, so it shouldn't be a problem and more when in one template works ok and not in the other.
I never had that problem before, so any suggestion about the possible reason?
Regards
