Mr. Bastian Ahlf 2 Report post Posted January 20, 2020 Hi, in my script i need to measure a length. The length that has to be measured (and adjusted afterwards) ends with the trailing edge of the following blade. The adjustment works well, but before running a huge DOE, i would like to know if the internal names remain unchanged after parameter update. In the attached picture i tried to visualize my question. The certain edge is named with "2" and can be found with BrepName.getEdge(2).... After some geomtry updates the name did not change and the correct edge was chosen - but is this ensured in any case? Many thanks Bastian Share this post Link to post Share on other sites
Ceyhan Erdem 14 Report post Posted January 20, 2020 Hi Bastian, That is a good question indeed.In a BRep the number of edges for a geometry variation of a certain object does not necessarily remain constant. Depending on your split method it may vary. So I would suggest you to use the source, which most probably is a surface.mySurface.getEdge1() or 2,3,4 would provide you the necessary edge. If you have further questions, please let me know. CheersCeyhan Share this post Link to post Share on other sites
Mr. Bastian Ahlf 2 Report post Posted January 21, 2020 Hi Ceyhan, many thanks for your advice. In case the names remain constant for surfaces, I am going to use their edges for measuring. Best wishesBastian Share this post Link to post Share on other sites
