It would seem that in AutoCAD you can have any shaped viewport you like, which makes things very easy. It means you don’t have to think about layers and hiding objects in the viewports etc. In Revit we currently only have the facility to create rectangular crop regions, and to be able to split them. Now this works fine under normal linear circumstances, but what if you have a curved building or a shape that required the crop region to be outside of the rectangular constraints. This is where the masking region can come into effect. Simply create a masking region that runs parallel with the building outline, change the lines to invisible, and hey presto, you now have a “shaped Viewport”!!!

Below is an example of the limitations when perhaps faced with a building with 2 external stair cores (Fig. 1) that I do not want to show in my base plan, to use the crop region ordinarily, would not allow me to cut out the cores without losing some of the main building. By using a masking region however in Fig. 2, you can see where the outline has been created and the result in Fig. 3.
