--- Comment #4 from Alexander Schier <alexander_sch...@yahoo.de> --- I do not mean "without changing the geometry" (as seen on the screen), but without changing the construction (as in some tree of operations or whatever the internal data structure does). So if i change the construction of a center of three points, i do not want to delete all segments which have the center as parent object, but keep them (and for example see how they change length and direction). So when i have some complicated construction, which contains MORE_OPERATIONS(MACRO1(input))), i want to swap MACRO1 for MACRO2, leaving input as it is (maybe some complicated constructed object as well) and changing the Output geometry by applying MORE_OPERATIONS to the changed object. Or like it would be in a saved file: Document: <Object type="FixedPoint" id="8"> <Parent id="7"/> <Parent id="1"/> </Object> <Object type="FixedPoint" id="9"> <Parent id="3"/> <Parent id="4"/> </Object> <Object type="CircleBTP" id="10"> <Parent id="9"/> <Parent id="8"/> <Parent id="6"/> </Object> <Property which="center" id="11"> <Parent id="10"/> </Property> Operation: Swap center(CircleBTP(input)) for polygon-center-of-mass(TriangleB3P(input)) Changed Document: <Object type="FixedPoint" id="7"> <Parent id="6"/> <Parent id="5"/> </Object> <Data type="double" id="8">0.790236</Data> <Object type="FixedPoint" id="9"> <Parent id="4"/> <Parent id="8"/> </Object> <Object type="TriangleB3P" id="10"> <Parent id="7"/> <Parent id="3"/> <Parent id="9"/> </Object> <Property which="polygon-center-of-mass" id="11"> <Parent id="10"/> </Property> Everything having <Parent id="11"> change its geometry after this, everything having <Parent id="10"> before would need to be deleted as there is no circle anymore (and a triangle has other properties). -- You are receiving this mail because: You are watching all bug changes.
