Summary	0033707: Modeling Algorithms - Use of BRepAlgoAPI_Defeaturing class leads to exception during Build operation
Description	An attempt to defeature the wheel rim model (attached) with the 5 surfaces groupings as shown in the image rim-2.0a.png results in an exception during the Build operation. If I exclude the forward-most and rear-most groupings as indicated (leaving only the inner set of 3 surface groupings), the Build operation is successful. The particulars of the exception are shown in except.png.
Steps To Reproduce	After instantiating a BRepAlgoAPI_Defeaturing object: 1) log the TopoDs_Solid using SetShape 2) SetRunParallel(false) 3) SetToFillHistory(false) 4) Load the TopoDS_face objects for each grouping using AddFaceToRemove(..) 5) Build() The TopoDS_face objects are loaded by grouping, and the order in which the groupings are added are random, so I cannot provide an order in which they are loaded.
Tags	No tags attached.
