Creating solid geometries using NURBS curve modeling
WIZEgem introduces a new interactive curve modeling (using NURBS). You can use a ready-made simple 3D geometries and edit them or create your own custom shape. It is very easy to use even if you don’t have experience in curve modeling.
- Select necklace jewelry type and from “solid geometries” set select a base element (if you create new it doesn’t matter which one).
The design is composed of at least one stage where you define the model in a semi-automatic way (and partially uniform) and an optional second stage where you can manually and in a full non uniform way.
Let’s start with the first stage
- Press edit and then select “new/edit curves” edit marker or press “Free” button to start the free hand mode and then press start.
- Press “Delete path” to delete all current curves or edit each by selecting it.
We define the 3D model by using 2 curves – horizontal curve (u) and vertical curve (v), where your 3D model is a combination of both. You can look at it as horizontal planes as defined by the horizontal curve along a vertical curve which scales it.
- Edit/create new horizontal curve – this curve defines the XZ (horizontal) shape of your model. You need first to choose if it consists of straight lines (degree = 1) or round curves (degree = 2). Then add your curves and move your control points to create a closed path. The horizontal curve will actually define the maximum horizontal plane of your model.
- Edit/create new vertical curve – this curve defines the YZ (vertical) shape of your model. You need first to choose if it consists of straight lines (degree = 1) or round curves (degree = 2). Then add your curves and move your control points to create non closed path. The Y value of this curve defines the Y location of the previously defined horizontal plane and the X value defines how (relatively) to scale it.
- Press done.
Now we will continue with the second stage.
- Press edit and then select “edit geometry” edit marker or press “Free” button to start the free hand mode, select geometry in the drop down menu and then press start.
- Press “edit shape” button on the top left.
- Press move button
- Click one of the control points you want to move which will add 3 translate markers for each direction
- Touch and move one of the markers in the direction you want to move the control point.
- Repeat 10-11 for other control points.
- Press “Done”.
That’s it!!! You have your curved modeled 3D object.
You can play with different curves and control points or use ready-made curves from our DB (in free hand mode) to better understand the u/v curves and combination.
