Mr. Karl Hohenberg 0 Report post Posted September 6, 2018 Hi, I'm having some trouble generating a volute geometry, specifically the tongue area. I have tried two different approaches but both don't give very clean results (see attached model). Does anyone have any ideas for how I could solve the problem? Another issue I have encountered is that in one of my Breps which I have trimmed using a curved surface, the trim edge is subdivided into several straight edges (see attached image where one edge is selected) instead of one curved edge per surface. Does anyone know what the reason for this could be? Many thanks!Karl Volute.fdbc Share this post Link to post Share on other sites

Ceyhan Erdem 14 Report post Posted September 12, 2018 Hi Karl, Can you please check the attached project file.It is a quick approach and I didn't play much with it but you can further develop it. I have added two feature definitions;- one for creating curve orientation consistency, f_revise_curves- and the other for the tongue surface creation, f_tongue Please check and let me know if you encounter any problems. For your question about the subdivided trim edge, I would assume that there is tangency discontinuity which is causing the edge to be subdivided. But you can easily get the trimmed edge group using the command, your_BRep.getEdgeFrom(operation index where the trim happens) CheersCeyhanVolute2.fdbc Share this post Link to post Share on other sites
