New Feature: Freeform Spline

Evan_ReeseEvan_Reese Member Posts: 918 PRO
I've been working on this one for a while, and I think it's functional and stable enough to go ahead and publish. It's like the native Fit Spline feature, but you can add points to and drag them around in 3D space. There's a bit more to it than than so give this quick tour a watch. I'll probably use it mostly to route wires, ribbons, straps, etc. I may also find that it's helpful for making reference curves when doing surfacing. You can add the feature from here. Let me know if you find it useful or notice a bug with it.

Here's an example of something I'd really dread modeling without it.

    That is very impressive and I have been wanting such a tool for mold design on 'organic' shapes.  Thanks for sharing!

    And I have to tell you - I am very interested in knots and yours had me going.  I thought, how cool a perfect figure eight.  But it is not an honest knot. :)

    It is a half hitch pulled open funny.  Although looks very cool and I appreciated the brain game.  I am going to make more knots with you feature.  :wink:

    Love it. Is anyone else having trouble getting the video? I keep getting the 404 message.

    Thanks, Bruce. I'm curious what mold design problems you're interested in solving with this. Any examples you can share?

    Just tested it out from another account and it worked. Try this link and let me know if you still have trouble.

    Nicely done, as always @Evan_Reese !

    @Jascha_Wilcox check it out.

    Impressive usage of manipulators and edit logic function. :o

    @Evan_Reese
    You asked how I thought this will help mold design.

    In words - when a parting line is a 3d curve designing the shutoff may be need curves are not equal distant from the parting line curve for blending purposes. A good 3d spline tool should allow creating these blending curves directly. Otherwise we do work arounds like projection or intersecting surfaces. 

    I will put an example together when I can make time.

    I could see this easily being the number one featured feature.

    Very nice feature Evan !
    This is going to come in handy

    @bruce_williams

    Bruce — upon reading your post above, I looked for something to tie the knot in the picture. My iPhone power cord turned into a half hitch before I could even finish. Thanks Bruce. That was interesting

    Looking forward to your blending curve example

    Thanks! Almost all of the code editing logic and manipulator functions with a teeny tiny opFitSpline to actually make the line.

    Very cool, @Evan_Reese! It's like @ilya_baran's Ortho Lines FS but but curvy ;) I agree with @konstantin_shiriazdanov - the use of manipulators is polished and makes this very easy to use.

    Seeing Ortho Lines a few years ago (or whenever that was) was the first time the lightbulb went off for me that this feature should exist, and I've only now gotten enough FS practice to make it. Thanks, @ilya_baran

    Very nice work, @Evan_Reese! I played with it and it feels very polished.  Using the points manipulator to keep the screen from being cluttered with the triads is a good pattern :)

    Hey @Evan_Reese, this feature is awesome! Thanks for putting it together and making it public. One point of feedback got brought to my attention:

    When editing in-context, you are unable to reference context vertices directly with this feature. It seems like the native curve tools are able to do this. I'm not sure if there are larger technical challenges associated with this or if it was simply overlooked, but figured I'd pass it on!

    Thanks, Daniel. Can you share an example of what you mean? I just tried this and it works. I can see why using this in context could be really valuable, so I want to make sure it works.

    @Evan_Reese

    This really nice. I like how you can tie a vertex relative to a mate connector so the curve updates with geometry. I'm trying to think of my next design so I can incorporate the use of your curves. I like the flexibility and control over a curve.

    Thanks, @billy2 I'm thinking of your cool cable routing presentation from the user group. This does seem like it would fit that workflow. I also just added a custom table to list out the lengths of all of the curves (thanks for the idea, @John_P_Desilets ). If you've used the feature in your Part Studio it will show up under "Feature-linked custom tables", so no need to add the table to "My custom tables".

    @Evan_Reese Ah, this way my own lack of understanding of the tool! I am able to get it working now. Thanks!

    Some check boxes that would be useful:
    • Draw multi-line segment instead of spline.
    • Keep points

    good ideas here, but I'm wary of feature creep. You may have seen I did a quick "3D Points" feature. Does that serve the purpose of a "keep points"? I considered making it all one feature, but I don't want to pack it with a bunch of operations that aren't going to be used interchangeably. For example, I'd probably never start with a spline, and decide I'd rather have the points instead. Making the points and the spline is a different case, I suppose, but for that you could use 3D points and a normal fit spline. I can also see how a poly-line type of behavior could be interesting, but can't picture the use-case. Can you sell me on them with some examples where they'd be used?

    A good example for keeping the points:
    You create a spline. Now you want another spline based off of that one, but with different offsets along the same points. Keeping the points of the original spline would let you easily reference the first spline. 

    I have no good defense for multi-line segment  :)

    Ok I like that example :) . I added it.
