What is WellingLures
WellingLures Oy Ltd is a company delivering lurebuilding supplies for private individuals and lure manufacturers. WellingLures website is source for lurebuilding components, tools and services. Key function in website is “Lurebuilder” application. It is a web based tool which allows you to design your lure geometry and save it in to a webserver. Based on digital information it is possible to create all kinds of tailored components and tools easier than for handmade sketches. Let’s for example say that you have done a lure of some length and you would like to make another version, just scale it up retaining the same body proportions. In Lurebuilder it is easy, just give the new version length, save the new geometry and order the body components from webshop. Or, if you would like to make a dozen slightly different test versions which would have one millimeter difference in height or body curvature – easy as click of a mouse in Lurebuilder. Digital saving format allows you also to get best out of future development. Our R&D is working constantly to create new offering which in most of the cases can be implemented to existing lure models – as long as we have a digital model of them.

See general presentation of LureBuilder in YouTube:
Lurebuilder uses your computer’s calculation power and your commands to create digital presentation of your lure design. End results are saved in to a webserver database in a format which can be in post processed in WellingLures and fabricated in to physical products, such as lure bodies, painting stencils, casting moulds etc. We update available fabrication materials in to webshop as we get them tested. You will get the advantage of e.g. 3D printing materials development without need to change you design. if there is some material you are interested of and we do not have it yet available, please contact our support. We'll check if we can make custom delivery for you.
Main components in Lurebuilder are:
- Command panel
- Side view
- Top view
- Cross section view
- 3D view
- Lure name field
Working with views
Zoom in / Zoom out
If you use a mouse with scroll button, you can zoom by placing the mouse pointer in to any view and scrolling
You can pan view by clicking your scroll button down and moving your mouse
Geometry & profile line
Geometry is shown with two dimensional black profile line (1) in top and side views. 3D view window shows full 3D view of geometry. Geometry can also be inspected in any angle in 3D view. Rotate the viewing angle by keeping left mouse button pressed in render view while moving the mouse. Green and blue axis help in determing how the lure is aligned in the view (green positive Y axis points "as the back fin" from the lures back and blue negative Z axis points from the left side of the lure)
Rectangular and round control points define geometry boundaries. They can be selected by left-clicking them. Selected control point is highlighted. Control points can be moved by selecting them, keeping the left mouse button down and dragging the point in to a desired location. You can also type in the desired new coordinate in “Selected point – X and Y fields and pressing “enter” from your keyboard.
Note that changing “cross section” proportions override control points in side and top views resulting to a non-uniform scale. If you want to keep side and top views exact, do not change control point positions in cross section or do not drag cross section handles so that section goes over original 1:1 bounding box.
Rectangular "nodes" are points through which geometry lines go. They can be in start and end point of geometry lines or somewhere between. You need at least two nodes to create curved lines.
Tangent & Tangent handle
Tangents are shown for each control point as red line. In both ends of tangent there are round symbols. They can be selected by left-clicking them. Selected tangent handle is highlighted. Handles can be moved by selecting them, keeping the left mouse button down and dragging the handle in to a desired location. You can also type in the desired new coordinate in “Selected point – X and Y fields and pressing “enter” from your keyboard.
Distance of tangent handle from a related control point determines how forceful tangent angle affects to the geometry. If tangent handle is dragged far away from a certain control point, there is more “wave” in the surface on that point. You could also say that the control point has then more effect to the geometry than those with shorter tangents.
Tangent does not need to be same length in both sides of a control point, they can be moved independently.
To affect, how smooth or corned geometry is near the control point, see Settings – Tangent mode
In render view there are red, blue and green lines which show direction of coordinate system’s X- Y- and Z-axis. These can be handy to observe if you do not always see from the view which side of the lure you are looking to.
As default tangents are “Smooth” i.e. they form a straight line through handles and control point which most of the time results to a smooth 3D surface. You can change the tangent mode to “Corner” from command panel. It is then possible to make corned tangents and surfaces. Note, that this type of surfaces cause challenges in many applications and postprocessing.
You can change the lure length with this form. Length is millimeters and is applied to the whole geometry when you press “Apply length”. You can change the length at any time.
This setting determines if both sides of profile line are mirrored relative to center line of the lure or not. Setting can be different for different views. You can check the current setting by placing your pointer to some view (checkbox shows the setting value). As default, top view and cross section use symmetricality as it gives you best basis for straight running lure. Changing setting from non-symmetric to symmetric keeps the last changed profile and overrides the other side of the lure with mirrored version.
Coordinates of selected point are shown in the user interface. You can also draw precisely by selecting some control point or tangent handle and giving the new coordinate value from keyboard. New coordinate is then applied by pressing “Enter”.
How to Use
- A) Start new project by clicking “New Lure”
B) Go to "Library" and select template that fits best for your target
Note there is no "undo" command, so practise saving frequently. Use "save as copy" to make new baseline where you can return when needed. Asterisk in "save" button is shown when lure has unsaved changes.
- In "Profile" tab, type in length in “Lure Length”
- You have a base design shown in views. Go in to any view and drag control points as well as tangent handles to desired locations to form your lure
- In "Bend" tab you can bend the design. This tab is there to allow curvy shapes which would have even two cross sections in some point. Note this tab should be used with caution and is recommended only for subtle changes or grub like softbait tails. Changes done in bend tab can only be seen in 3D view, in profile view you can still work with the original design. "Reset Curve" button removes all bend commands and you get back the straight design, if needed
- In "Components" tab you can add components like diving lips, figure 8 forms, weights etc. to your design. Use by clicking "Add component" and select desired component from library. Components are first added in to origo and can be selected from their center node. Selected component name is shown in tools panel. You can move selected component by dragging it with mouse. There is also rotation circle around every center point. You can rotate component by clicking anywhere in rotation circle edge and dragging by mouse. Moving and rotating can also be done from tools panel.
If you want to remove a component, select it and click "remove component". Note, that components do not scale with the lure. if you change the lure length, you need to reposition components and consider changing them to smaller or bigger versions as well.
Components you want to locate in to both sides of the lure symmetrically can be mirrored. Position one component first, keep it selected and press "Mirror component". Command creates another independent copy of the component (If you reposition either one, other does NOT follow - keep this in mind when finetuning the component locations)
- When you are satisfied with the geometry, save it to webserver with a name you can recognize. Name of the lure is typed in to name field and accepted with enter from keyboard.
- "Share lure" button gives you possibility to share the image of your lure and 3D view access in socila media channels like facebook, Google+ etc. Note, that sharing does NOT give anybody else possibility to modify the lure.
- Go to the “Webshop – Your own design” and order products based on geometry you saved. You can also use "Order lure" button in Lurebuilder left bottom corner, it takes you to webshop and directly to the lure you have in Lurebuilder view.
Working with cross section
Cross section is applied to the whole lure length by stretching or scaling it between top and side profile. Cross section is therefore not exact and exists as it is drawn only in such points where both side profile and top profile are as wide. If you want to get for example narrower belly than back of the lure, you can adjust the profile accordingly by changing the profile line side tangents.
Note, that cross section is limited by top and side profiles only if cross section sides are in original 1:1 ratio. That means, if you change location of any control point in cross section profile your side and top profiles are not any more exact borders of the lure. If you want do design for example lures of some preferred width or height we recommend you observe first how cross section changes affect to some test design.
Tips and recommendations
Reservation for coating
Note that in Lurebuilder 1.0 version (check release notes as this might change in the future) you design lure body as an unfinished component and you need to consider manufacturing requirements, too. For example, if you design lure to have 5mm thick rear, you most probably get much thicker end product as you need to apply paint and coating. On the other hand, very thin forms would not be possible to manufacture as components in all materials.
Our R&D is working to get visualization of coating effect in to next releases of the Lurebuilder.
Minimum rear thickness
These are minimum dimensions for our manufacturing technology – they do not represent what would be the minimum need in real application. If you are designing lure for deep sea predators, you might want to make much more sturdier shapes.
- Wooden bodies – 2mm
- Plastic bodies – 0,5mm
Less control points is often better than more
Title says it all. Typically new users create lots of control points and then try to do small changes to them to get smooth surfaces and turns to the geometry. This often results to stacking change need and end result still has some “corners”. Most of the times the same goal would be reached by with fewer control points and fine-tuning their tangent handles. In early test phase we were able to make best traditional shapes with only one control point between start and end of the profile line – as long as the tangent mode was selected to be “Smooth”.
Work with render window
Making geometry with the Lurebuilder is easy and you can see the changes immediately in render window. However, sometimes screen can be hard to interpret how the physical end product would be like. If you have a certain curvature of surface in your mind, we recommend you would turn the design in render window in to any possible angle before continuing to saving and ordering it. It’s good especially to look long objects both from front and rear close angles to see how lure’s back and belly curves look like.
Do not make crossing surfaces or profile lines
This is actually a must for us to be able to make your components – all design must be consistent. If your profile lines cross, it means that in the crossing point geometry would actually be splitted to two pieces. Even if this kind of situation could look doable in two separate pieces, calculation method in backline of the Lurebuilder can not recognize what it should do with such a geometry. At least in the Lurebulilder version 1.0 we do not have a checker function to warn about such cases. They are noticed in production phase and resolving the case takes unnecessarily time from your process.
Good to remember in dimensioning
Measurements you will give are for 2D / 3D computer model. When manufactured in real life your model will face manufacturing tolerances, coating, shrinking etc. depending on processes you will use to finalize your lure. Keep on mind at least following phenomena:
- When you coat your lure, thickness and length of the lure increase. When placing your components, leave some space for coating, otherwise you end up having e.g. useless line attachment loops as they are filled up with coating.
- If you order 3D printed parts from your design, 3D printers tend to close small grooves and cavities more than little big bigger cavities. Also surrounding geometry affects, what kind of end tolerance cavity will have. We have done our best to add just perfect reservation for each component dimensions, but sometimes component cavities might get too tight or loose depending how much material there is in your design surrounding the component. Unfortunately there is no way to make custom tolerances for each component in each use case so some postprocessing might be needed for your 3D prints.
- We have added typically 0,2-0,5mm in to each component size in order to compensate cavity shrinkage in 3D prints and to reserve some space for glue in final product. If you print out your design in to paper, drawings include this tolerance. Just as you are aware of this. E.g. 10mm ball weight 3D model in LureBuilder component library has actual 10,4mm diameter.
- If you use your model as master object for making casting molds, there will be shrinkage in final product. Amount of shrinkage depends on casting method, your mold design and casting material. Due to this you can not always use exactly the same 3D model in different applications. if you have created for example 3D painting stencil for lathed lure, same stencil does not typically fit for resin casted version from that same 3D model, you need to adjust the dimensions.
- Lurebuilder adds automatically left and right side supports for components you add to hollow models (there can also be special components without supports in the library. They are meant for solid lures, indicated in component naming). These supports have also automatically draft angle in one direction, it helps making casting molds. Unfortunately, we have not yet found proper mechanism to add draft in to hollow lure body itself (situation at least with LureBuilder 1.0). If you plan to cast your design in non-shrinking casting method and use metal materials, please consider adding the draft to cross section profile yourself. Also, draft is hardcoded to the component itself, not to the geometry where component is placed. It means you will loose the advantage of draft if you rotate the components much. For example if you insert 3D eye components and want to have small cavity for them. You can take 3D eyes from library, but when you position them to very curvy part of the lure head (e.g. very front in thick lure head), they point more onwards than to side. This causes draft angle is not aligned any more to the sides. This should not be a big problem if you make molds from soft materials, but for making a CNC routed mold from metal it is a negative phenomena.
Non symmetric lure bodies (advanced users only)
As a rule of the thumb all lures should have symmetric sides to get them running straight. However, for lightweight lures targeted for just a certain speedzone – casting or more usually trolling, sometimes non symmetric shapes can bring unexpected movement. Sometimes unexpected is a good thing, but prepare yourself to get also non working geometries if you go this way. Non symmetrical shapes are used especially with saddle shape diving lips and lure bodies made of balsa. Difference of sides needs to be minimal. Some pros tune the lures first to carve to another side from lure body or even by turning belly and rear hook attachment loops. Then they correct the movement to run straight from line attachment loop. Result can sometimes be a lure which can not take much of speed, but starts to “scatter” deadly in a limited speed zone before swim motion fails. Lure can even seem to go straight and make irrational shakes every now and then in this speed zone – sometimes very catching movement.
