GK_YD 0 Report post Posted August 27, 2023 (edited) Dear all, I'm having some issues trimming the Brep or Surface either with curves, surfaces or Breps. My intention is to parametrize the end of the Brep or Surface in order to end at the transom (x=0) of the hull, while at the same it follows the step. I manage only to trim the surface (04_UpperSectionSurface) first on the principal plane (X=0) first and then trim the Brep (06_Step|Upper_Section_Brep) on the step geometry, however this ends with some discrepancies on the final Brep, due to the initial trimming of the 04_UpperSectionSurface. I'm attaching a few screenshots of the area, while also the model. Could you please advise upon the matter? Thanks a lot.

Mr. Claus Abt 14 Report post Posted September 27, 2023 The reference points for the trimming did not hit the Brep. Alos,is there any reason why you took 2000 sections for the bottom surface? TestSWAN_v2_trimmed.cdbc Share this post Link to post Share on other sites
GK_YD 0 Report post Posted October 4, 2023 Hi and thank you for checking up the model. I checked on the proposed solution and also found the problem you've mentioned via another way of trimming the excess surface/brep. Regarding the No. of sections, I think I've left them 2000 by mistake, on the process of checking the potential of the surface and how it was displayed. Now I've returned both values (Interpolated points & Number of Sections) to 10 & 100 respectively, as of a previous suggestion of yours (on another post of mine). I'm attaching the new file below, while I'd like to ask how should I close the bow upper section of the hull (till the X-plane) in a fair way, by assuring continuity in curvature (attaching relative photo as well)? Thank you again for your time. Best, George TestSWAN_v3.cdbc Share this post Link to post Share on other sites
