After editing parametric window in Bonsai 0.8.4, how to restore glass transparency and frame color?

Darius_Hisem · March 24

Hi everyone,

I'm using Bonsai BIM 0.8.4 in Blender.
I created a window using Bonsai and clicked Enable Parametric Geometry' in the Bonsai properties panel After that, I changed its dimensions (width/height) and adjusted the type/style based on the parametric options.

After finishing the edit, I noticed that the visual appearance was reset:

the glass is no longer transparent and appears as a solid object
the frame no longer has the assigned color
in Solid viewport mode everything looks like a single opaque object

My question is:
What is the correct workflow after modifying a parametric window to:

Make the glass transparent again
Reapply a specific color to the frame
Ensure these are visible in the viewport (including Solid mode)

Should this be done using Blender materials, Viewport Display, or IFC styles in Bonsai?

Thanks!

@Darius_Hisem
yes, you need to have at least two style, for frame and glass pane (with transparency)

method 1 (parametric window)

a easier way is to use a parametric window editing panel, at the bottom you can conveniently assign the available materials

method 2 (non parametric or custom window)

you need to work with a Material Constituent Set

then you apply the styles to relevant material

once done you can use IfcMaterialConstituentSet to have them assigned to the type or element

and last use Representation Items to assign style/material to the part making the window

happy modeling
