    Hi Jaap,

     

    Good finding - thanks. We used to have this menu, you can still find these features in this blog post.

     

    Dear Jörg,

     

    The file location where the old features should be placed according to the blogpost is wrong for a Linux installation.

    (I am running CAESES 4.2.1 running on Ubuntu Mate 16.04.2 LTS besides running it on Win10)

     

    The blogpost points to

    ~.friendship/etc/features

    , but that should be

    ~.friendship/features

    otherwise the features still won't show up under "Features" >> "In User Directory".

     

    Cheers,

    Hi all,

     

    Can anybody point me to the way to use the getDisplacement function of an FSurfaceGroup type surfacegroup? And while we are at it: should there be a "hull design" group of features under the features menu?

    (I am searching for the menu "features > hull design > displacement from surface group" as mentioned in the tutorial "hydrostatic calculation" in the box at the bottom of page 1, which does not seem to be there in my version of CAESES).

     

    Kind regards,

    Hi all,

     

    I am trying to figure out how to create a solid (meshable) using a nurbs surface (either imported from Polycad/yachtlines as an IGES surface or created using the "initial B-spline surface for hull design sketch) and the offsetsurface command. Any thoughts on that, bacause I am not able to figure out how to do that in a way where I can manipulate the hull shape later.

    Is it possible to use the perimeter edges of both for a ruled surface (how should that be done?) and then convert the closed volume to a solid?

    Or even just close the volume with said ruled surface and then mesh the volume defined by the B-spline surface, the offset surface and a ruled surface connecting the first two?

     

    Regards,

    Any thoughts on how to activate my last CAESES Free license (running to the end of June 2017) on a new Linux laptop (as the screen physically broke off of my old one)?

     

    On my old laptop I had been able to update to 4.2 from within the application, but installing 4.2 on the fresh machine doesn't seem to offer registering with my Free license.

    Hello all,

     

    I have modelled the hull of a sailing canoe after a lines plan in a book from the 1930’s in Polycad. I exported the B-spline curves describing the chines to iges from Polycad and imported them into CAESES (Free). Then I had CAESES generate developable surfaces between the curves. So far, so good.

     

    But although the documentation states that upon export of a developable surface to iges both the 3D representation and the unrolled surface will be exported, at first I did not see the unrolled surfaces in the iges file. Neither when opened in another CAD software package, nor when inspecting the file using Notepad++.

     

    During time that elapsed to have a small hick-up with my forum account fixed, I found that the unrolled surfeces will be exported when the "IGES (Deprecated)" export function is used, just not with the standard "IGES" export function. I do hope the possibility of exporting developed surfaces will not disappear with the removal of a deprecated function.

     

    Has anybody found out how to get the unrolled surfaces into a "2D window" and generate 2D drawings and/or print files of them in the 2D environment of CAESES?

    At the moment I am exporting the unrolled surfaces as an IGES file again, have Polycad translate the iges file to dxf and use Draftsight to turn these into prints. Is this the optimum route to take, or have I overlooked possibilities in CAESES?

     

    Regards,
