Summary | 0004494: Error "Result is empty" for Pads and Pockets with non zero Offset | ||||
Description | In some cases Pad offset does nothing in others it works. I couldn't find out the criteria. In the corresponding forum post I have attached an example. Steps to reproduce: - load the file PadOffset.FCStd - double click Pad001 - change Type to one of ToFirst, ToLast, UpToFace - if changed to UpToFace select one of the faces parallel to the sketch, e.g. the selected face in the post. - change offset to 10, any other value <0 or >0 will do as well - confirm: error "Pad: Result is empty" occurs Same behaviour is shown if the changes are made without the dialog directly in the Data tab. | ||||

|
I can observe the behaviour with a pad but not with a pocket. The reason for the problem is if the Fuse parameter of BRepFeat_MakePrism is set to 2 when an offset is set. Both of the values 2 and 1 does a fusion while for 0 a cut is done that is used by the pocket. The solution (at least in this case) is to use the value 1 if at the same time an offset is used. |

Fix committed to master branch. |
