class ifcopenshell.api.grid.create_axis_curve.Usecase(file, axis_curve=None, grid_axis=None)#

Adds curve geometry to a grid axis to represent the axis extents

This currently depends on the Blender geometry kernel to function.

An IFC grid will have a minimum of two axes (typically perpendicular). Each axis will then have a line which represents the extents of the axis.

Parameters
Returns

None

Return type

None

Example:

# A pretty standard rectangular grid, with only two axes.
grid = ifcopenshell.api.run("root.create_entity", model, ifc_class="IfcGrid")
axis_a = ifcopenshell.api.run("grid.create_grid_axis", model,
    axis_tag="A", uvw_axes="UAxes", grid=grid)
axis_1 = ifcopenshell.api.run("grid.create_grid_axis", model,
    axis_tag="1", uvw_axes="VAxes", grid=grid)

# Assume you have these Blender objects in your active Blender session
obj1 = bpy.data.objects.get("AxisA")
obj2 = bpy.data.objects.get("Axis1")
ifcopenshell.api.run("grid.create_axis_curve", model, axis_curve=obj1, grid_axis=axis_a)
ifcopenshell.api.run("grid.create_axis_curve", model, axis_curve=obj2, grid_axis=axis_1)
