Using the CW tool, you would have to create each facet as a separate angled curtain wall. The CW tool doesn't angle multi-segment lengths, so you have to create an individual CW segment. This you can adjust to the right shape etc and then multiply copies to get the length and shape of the entire wall.
-First create using a sloped/angled wall the multi-segmented wall shape .
-Then I created on top/same outer plane, create a single CW segment.
-In the 3D CW editing window edit the scheme so it will be one panel; just oversize it and then it will place a frame along the edge.
Using the wall as a guide (have the show environment box checked) align the corner points of the CW polygon to a wall segment's 4 points.
You can save the scheme as a favorite.
