I have a number of dynamic shapes which poured correctly but after checking the Constraints Manager for errors. Some of the pours failed to pour or gave unusual shapes.
Like here where the re is a static pour to illustrate where it should pour and yet the dynamic pour adds a strange curve.
Or here where the outline is shown in light and there should be high voltage clearance to the pads, but the pour has added a joining curve to the pour which was not requested.
This is in Cadence 16.3-053 as we cannot update the design to the latest.
