Hi Claus, Thank you for your reply! I already created a ticket concerning this this hull, however not about the issues connected to the the ruled surface, and have got help from Fabian Thies who looks at the ship in general terms, so I can ask him more about the ruled surface tomorrow if I'm not satisfied after playing with the parameterization. Kind regards, Gustaf

Hi, I'm modeling a ship hull and have generated a ruled surface between two generic curves (see the attached figures). However as you can see the surface doesn't look good slightly forward of LOA/2 and forward to the stem. The surface also bends inward, creating a curved surface and I'm wondering how I can fix these issues. I want the surface to be completely flat between the two generic curves and thought that a ruled surface should work, but I do not really know if a ruled surface is the best choice and if it can be controlled like I want to. If anyone can explain how I can control the surface and make it completely flat that would be great. Thanks, Best regards, Gustaf

Hi Heinrich, No worries! Thank you, yes, I wanted to have the parameter position corresponding to the max z value. I will have a look in the project you fixed. Thanks again! //Gustaf

actually Heinrich, The x-value of the maxZ point was set as a discrete value. I want to automaticly retrieve this x-value based on the maxZ point, which change position if I vary the shape of the "knuckleRaiseCurve" Thus, if I vary the shape of the "knuckleRaiseCurve" in the xz-plane the point maxZ automatically get the max z-value, but I want to automatically also retreive the correspoinding x-value, when maxZ position changes.

Yea, it was, 🙂 Thank you Heinrich!

Hi Heinrich, I actually use :z to get the z-value, see attached screenshot. planing_hull_v03.cdb

I could also say that the b-spline in the center works as a control curve and controls the outer generic curve in the z-direction. The point on the b-spline which is marked with "1" thus also has the correct x-value. I control the generic outer curve in the xy-plane with a multisegmented curve (not visible in the screenshot).

Hi again Heinrich, I tested what you suggested and the points were created, but the position was wrong. I attach an image so it becomes easier to explain what I want to do. The point I have marked "1" is the point which has the z-value I want to use. The red cross marks the approximate position on the curve where I want the new point to be. The point in the bow which I have marked with "2" is where the point actually is positioned after creating the point with: point p(curve.fv(2,zVal)). I also tested the command: point p(curve.ft(2, zVal)) but then the point was positioned really far aft (not visible on the screenshot). I hope this helps to describe my problem. Thanks again! //Gustaf

Thank you Heinrich, I will try this and also the ft alternative that you suggested //Gustaf

Dear forum members, Is there an easy way to find the normalized value, that represent a certain real z-value, that I can use for the "Tp-value" when using the point type "position on curve"? Thanks, //Gustaf

Hi Claus, At my work we have both versions, but since I'm relatively new to use CAESES and my "mentor" has not used C5 yet, we decided that I should use C4 while I'm learning our templates for ship hulls. I have started to use C5, though, and my plan is to only use C5 very soon. Kind regards, Gustaf

Hi again Mr. Claus Abt, I cannot find the "Weight in Tree" setting in CAESES 4, but I find it in CAESES 5, so I guess this is a new feature only available in C5!? Kind regards, Gustaf

Hi Mr. Claus Abt, Thank you for the reply and description of how to organize the contents. Kind regards, Gustaf

Dear CAESES users, I would like to organize the object tree, but the usual "drag & drop" feature does not work and I cannot find another way, like an "edit-mode", that allows me to move, for example, FScopes and FParameters up and down in the object tree and thereby organize the contents. If there is a way to organize the object tree, I would be very grateful if someone could enlighten me. Thanks, Kind regards, Gustaf Magnander

Hi Heinrich, Thank you very much! Best regards, Gustaf
