"""Add a new presentation style
|
|
|
|
A presentation style is a container of visual settings (called
|
|
presentation items) that affect the appearance of objects. There are
|
|
four types of style:
|
|
|
|
- Surface styles, which give 3D objects (which have surfaces / faces)
|
|
their colours and textures. This is the most common type of style.
|
|
- Curve styles, which give 2D and 3D curves, lines, polylines, their
|
|
stroke thickness and colour.
|
|
- Fill area styles, which gives 2D polygons and flat 3D planes their
|
|
colours, hatch patterns, tiled patterns, and pattern scales.
|
|
- Text styles, which gives text their font family, weight, variant,
|
|
size, indentation, alignment, decoration, spacing, and transformation.
|
|
|
|
Once you have created a presentation style object, you can further
|
|
define the properties of your style using other API functions by adding
|
|
presentation items, such as ifcopenshell.api.style.add_surface_style.
|
|
|
|
:param name: The name of the style. Used to easily identify it using a
|
|
style library.
|
|
:param ifc_class: Choose from IfcSurfaceStyle, IfcCurveStyle,
|
|
IfcFillAreaStyle, or IfcTextStyle.
|
|
:return: The newly created style element, based on the provided
|
|
ifc_class.
|
|
|
|
Example:
|
|
|
|
.. code:: python
|
|
|
|
# Create a new surface style
|
|
style = ifcopenshell.api.style.add_style(model)
