[Plugin] Extrude Edges by Rails

[Plugin] Extrude Edges by Rails

Postby TIG » Mon Nov 16, 2009 10:18 pm

The tool has been optimized and improved to use a 'melding-profile' at the end if desired...
It has various glitches fixed and a new combined Toolbar...

    ###
    extrudeEdgesByRails.rb
    ###
    Extrudes an 'initial-profile' curve along one or two other 'rail'
    curves to form a faced-mesh group, a final 'melding-profile' curve
    option can control the mesh's final form.
    ###
    Usage:
    Make 2, 3 or 4 'curves' (Arcs/Beziers/PolyLines/Welded-Edges etc).
    These will represent the 'Initial-Profile', the first 'Rail',
    the second 'Rail' and the 'Melding-Profile' - these last two
    curves are optional - see below...
    The 'Initial-Profile' should share a common end vertex with each of
    the 'Rails': but if it doesn't it will be scaled to fit between
    these Rails and that might then have unexpected results...
    If you pick Rail-1 and then click on it again it will be used as
    Rail-2***, as if it were at the other end of the Initial-Profile.
    Then you are asked for the 'Melding-Profile': you can pick on
    the 'Initial-Profile' again to form a simpler mesh from just
    that one Curve, with it being proportionally scaled and rotated
    at each of the Rails' nodes - this method gives you little
    control over the rotation of the Final Profile as this is
    calculated to rules automatically derived from the Rails'
    relative node positions etc: however, if you pick on a
    different Curve [note that it can't be one of the Rails] that
    will then be used for the Final Profile at the Rails' end nodes;
    so using a 'Melding-Profile' like this means that all of the
    intermediate Profiles will have a proportional 'melding'
    between the 'Initial-Profile' and the [Final] 'Melding-Profile'
    along the Rails' intermediate nodes: with this method you can
    determine the 'morphing' of the Profiles along the Rails from
    an initial form to a final one, or alternatively you can use
    the same shaped 'profiles' for both, but with different
    rotations/scaling, so that you can then effectively 'lathe' a
    profile along non-circular rails and be sure that the initial
    and end profiles will be formed and located as you want them...

    Looped curves for the profile or the rails are allowed,
    but they can give unexpected results... also don't try a
    melding-profile with looped rails unless you want the unexpected!

    Run the Tool from Plugins > 'Extrude Edges by Rails'.
    or click on Toolbar 'Extrude Edges by Rails'.
    Activate this Toolbar from View > Toolbars if not loaded.
    Follow the prompts on the VCB.
    Pick the Curves in the order instructed...
    First pick the 'Initial-Profile', then pick the other two 'Rails'.
    You aren't allowed to pick the same Curve twice in this set of 3
    unless Rail-1 is also to be used as Rail-2***.
    Fourthly you pick a 'Melding-Profile', or you can pick the
    'Initial-Profile' again for a simpler mesh form without a fixed
    final-profile form etc.
    After selecting these curves it auto-runs the mesh-maker...
    A grouped triangulated mesh is made based on these curves...
    Then there are dialogs asking for Yes/No replies...
    If you want to 'reverse' rail-1's direction.
    [usful if the mesh is 'twisted', when the rails go in
    opposite directions...]
    Note that this dialog is omitted if Rail-1==Rail-2.
    If you want to 'reverse' the faces in the mesh.
    If you want to 'Quad' faces [i.e. smooth just the diagonals]
    If you want to erase any 'coplanar edges' in the mesh.
    If you want to 'intersect' the mesh with itself.
    If you want to 'smooth' the edges in the mesh.
    If you want to delete the original curves.
    You can Undo these steps individually immediately afterwards...

    NOTE:
    Multi-segmented curves increase processing time exponentially...
    ... the mesh WILL eventually be made, but the screen might
    'white out' and it might appear to stop for several minutes...
    but it is working...
    Rails/Profiles with the same number of segments/edges or with
    them as simple 'multiples' will produce the fewest facets.
    It is sensible to 'match' the segments in profiles/rails,
    otherwise a mesh can become VERY faceted or possibly uneven -
    and also it might take ages to make.
    For example, for two rails their segments for each part of a
    profile are dictated by the most segmented rail's total number:
    10 + 10 segments=10 x 2 = 20 facets
    10 + 9 segments=10 x 2 = 20 facets
    10 + 5 segments=10 x 2 = 20 facets
    10 + 2 segments=10 x 2 = 20 facets
    10 + 1 segments=10 x 2 = 20 facets
    The lesser segmented rail will always have some of its segments
    re-divided to match the more segmented rail's total number. This
    division is spaced evenly for rails that are segmented as
    multiples, but this can only approximate to 'even' otherwise...
    The same applies to the profile/melding-profile's segmentation.

    For a rail/profile that is to be 'linear' draw an Edge & Divide
    it as needed equivalent to the number of 'facets' required or to
    match its opposite rail/profile, then 'Weld' the pieces together
    into one 'straight' curve.
    If you want a single Edge as a rail/profile then make a
    single segment Polyline with BZ Tools, or make a Curve out of
    two edges [with Weld etc] and split the Curve with another
    perpendicular Edge and Erase this and the unwanted Edge in the
    Curve - then you have a Curve with a single Edge - alternatively
    Divide the Edge into two and get a seam in the mesh - you can
    always use a 'Erase-Coplanar-Edges' tool to minimize the
    divisions later or you can always add back any lost triangulation
    by using the 'Triangulate Quad Faces' tool...
    Occasionally Curves made from welded/re-welded/re-re-welded[!]/etc
    have vertices in an order that can be unexpectedly convoluted
    and create weird results - if you remake the Curve from scratch
    it should be OK. Sometimes cutting and pasting-in-place or
    grouping and exploding a problem curve can also fix it for use...
    If you want a simple circular 'Lathed' shape use 'extrudeEdgesByLathe'
    - it will give different results from 'byRails' mesh.

It does resolve the issue of unequal segments in the rails (== the profiles used in 'Loft'), however, then you do need to set the 'profile' curve (which is the unchangeable 'bezier-path' pre-set in 'loft'!)...
AND if the rail segments are not equal or at least simple multiples the facets made might multiply unreasonably !!!

Feedback please... it's still a little buggy...

I think that's because the profile (now rail1) would need to be infinitely small where the two rails (profile+rail2) meet... I think it's trying to make tiny faces in the 'corner'... I know of this glitch and I am looking at ways of trapping it - it's not 'foolproof' yet ! ;)

Meanwhile use logically... :|

really beautiful, thank you so much.

i used it with the BZ toolbar, and you can set the segment amout for the line at the start which is a real time saver!

Looks like it has a lot of potential, :bounce: I have not had time to try it yet.
I was wondering if you had included, "Triangulate" or "Quad" face options?

cheers!

I am looking how to fix this within the script - to fix it manually for now use scale -1 on the profile about the profile's centre...

The curious thing is that the Rail2 is a "straight line"
So must be divided , then welded
But result seems no reproductible and gives some nusty result :o

PS A multi-profils along Rail1 rail2 will be sweet too :enlight:

Pilou:
I had similar results with the construction points on several attempts. Once, with rails made by Freehand tool and once with profile and rails made by Welded segments for profile and rails and once by smoothing out the profile with added arcs and Welding.
Since TIG said the script was mostly stable, I figured that there would be some of this to happen.

Can you all give as much info about the failures as possible [PM me small skps if appropriate] Ruby Console messages etc - I want to debug this glitch :roll:

Thanks for the Example skp.
I will try to provide you with examples as time permits. And I have been observing the Ruby console.
My last experiment was with Polyline Divider as the profile and rails from Fredo's Bezier collection. I got the mesh ok, but of course, the math complexity reversed and crisscrossed the beginning and ending copies of the profile causing an oblate spheroid bulge(same shape as an American football) and wings like Pilou's harlequin flying fish. However, there was no comment in the console.
Unfortunately the file is saved on my home machine. I will have to send it later.

hey TIG
here's a problem i've run into sometimes in an instance where it seems it should work. i'm only getting partial results in this case.
any ideas?

using that same file, here's another weird thing i can't figure out. (a video's probably easiest for me because i don't have to type as much :D)

(at first, it shows the problem i was previously talking about)
after that, i copy/move the profile and each rail the same amount along the red axis.. then end up with entirely different results.
