...basic shell expansion...

[...basic shell expansion...]

Hi,

 

   please find attached example feature definition (basicShellExpansion) which simulates expansion of hull surface curves ( longitudinals, decks, stringers,...) in transverse direction ( typical shell expansion drawing...). Inputs are hull surfaces(surfaceGroup), seriesParameter which defines frames layout and the hull curves for expansion...Feature generates background and expanded curves in Z=0 plane and is set to be updated on user request...

 

   It is far from complete but it covers basic functionality...I think it's cool   :)

[sorting offsets]

Hi,

 

  I've prepared two features which sort/remove duplicated offsets from input offsetgroup. Each has to be updated on request...

 

Brgds,

Tonci  :)

[sorting offsets]

Hi Claus,

 

    in attached file I've played with offsets in removeDuplicateOffsets scope...offsetgroup ofgr2clean is set such to have two pairs of duplicated offsets...

  

 

    I was hoping that ofgr2clean.removeDuplicates() will delete two frames from the list but it wasn't so...could it be that removeDuplicates function acts on points inside the offsets and not on offset inside the offsetgroup?

 

    I guess removeStrictlyMonoticViolation function has the same scope ( offset points rather then offsets ) ?

[function arguments...]

Hi Arne, thank you for these insights...I'm looking forward to new release!

 

...could you please re-upload your testing project, I'm not able to see it...and definitely, it'll be very interesting to explore...

 

Many thanks!

Tonci

[sorting offsets]

Hi Claus,

 

   offsets are extracted from two section groups and then added to one offset group...I'd like to clean and sort resulting offset group before using it in foreach statement...

[sorting offsets]

Hi,

 

  i'd like to sort an offsetgroup by x position of the included offsets ( which led me to my other post today... :) )...duplicated offsets should be deleted...i've tried with sortbyaxis and  mergegroups functions but with no success...

 

appreciate your advice...thanks!

[function arguments...]

Hi,

 

 I'm trying to implement quicksort algorithm to object list with FDouble elements and there are several questions I'm struggling with...In feature quicksort01.fdfc,  function argument forSort seems to be recognized as FObjectList in lines 11 and 15, but not in the foreach statement in line 25...where's the catch?

 

Part of this function should deal with concatenating several object lists into one...In second attached feature concatenateLists.fdfc I've done it with three separate foreach statements...Is there a way to make this more compact, say, in a loop statement?

 

Please advice...

 

Thanks,

Tonci

[Tank half full]

Hi Claus,

 

I've encountered some difficulties reading the file...certain functionality seems to be missing in version I have ( FProjectionCurveObsolete ) so model is only partly evaluated...But anyway, I was able to check new TriMesh definitions...

 

Whow! This postprocessing TriMesh functions are really, really powerful !   

 

Thank you very much for these insights!

[Tank half full]

Hi,

I'm trying to model a tentative tank configuration and so far I've managed to simulate movement of the fluid level more or less as I wanted ( only in a wireframe though)...Geometry of the fluid free surface is quite interesting. It's self-adaptive to number of tank sides at current elevation...But to complete the model I need to answer few more questions :huh:

 

1) how to model a solid below the fluid level? The idea is to track the current percent of tank filled in relation to full tank capacity.

2) is there a way to avoid warning masage for projection curve |tank|fluid|level|outerLevel|outerLvl2 , which cannot be generated    above a certain point?

 

thanks in advance,

Tonci

[Line equal segments]

Hi,

 

   this feature connects two input points with the line and divides it in N equal segments...funny thing is that when you move start or end point, line gets always divided in the same proportion  :)

[Modeling points within the loop]

Hi Arne,

  ...exactly what I was searching for  :)

Many thanks!

[Modeling points within the loop]

Hi,

 

  I'd like to model several points with the feature; every point with it's unique name...I'm trying with the attached code, and it seems that list is filling ok, but only the last loop iteration seems to be reflected in the model ( point p9 ). I sense some detachment is needed but can't figure it out :huh: ...appreciate your advice!

Thanks,

Tonci

[Tangent continuity between two curves]

...I wanted to quickly visualise mirrored point...we can just lower the degree of the b-spline 'mid' to one and drag p3 around...

[Inflection points]

Hi Claus, thank you very much on swift answers! This is very fine example of the powerful fspline features. Combining techniques you suggested, it is possible to obtain very nice and usefull sectional shapes...

[Inflection points]

Hi All,

 

  it's nice to be part of  FFW / CAESES forum!

 

  I'd appreciate your advice on some ideas I've been playing with for some time now...

 

  For the all curved transverse section I'd like bottom to be part of an ellipse, connecting to upper curve with G2 continuity. Furthermore, I'd like to control the position of the inflection point of the upper curve ( with  some basic curves for example, for construction of the hull metasurface...)

  Still not sure about bilge area up to waterline, but I should be able to control immersed sectional area of the wet curves combination...

 

 

Thanks in advance!
