Pcell symbol with curved shapes using dbCreateArc failing

Hello,

I am trying to create a pcell symbol with small curved shapes.  When using dbCreateArc, I am constantly getting - *WARNING* (DB-270000): dbCreateArcByBBox: The arc bounding box incorrectly intersects the ellipse bounding box.  I cannot seem to find any information on how to correct this.

Sample code:

cv = geGetEditCellView()
lineLayer = '("device" "drawing")
arc1 = dbCreateArc(cv lineLayer list(0.08125:0.1375 0.13125:0.1875) list(0.08125:0.1375 0.1125:0.1875))

Any suggestions?
