Opacity of objects changed to 100% when extruded

Desk shown here was created in Vectorworks 2019.  The extruded shape for the desk top retains the 50% opacity after extrusion in the final shaded polygon viewport.  However the circle created in Vectorworks 2022 with same color and opacity (50%) loses its color and transparency.  It changes to a dark gray opaque object in the final shaded polygon viewport.  In general, extruded objects are not appearing as expected in the final shaded polygon view.  I have experimented with classes and fill colors with no success.  Any thoughts?

Opacity does not apply to 3D objects. It is a 2D only attribute.

 

For 3D objects like the extrude, you need to apply a Texture that has transparency.

 

Check the Render tab of the Object Info Palette (OIP) for the desktop and you should see that it has a texture applied.  Apply the same texture to your extruded circle and it should show you transparency.

I am having trouble replicating the texture of the desktop with the extruded circle.  Shown is the Render Tab when these objects are selected

I applied a texture called Glass Blue 02 on a wild guess and got the desired result.  Hopefully I can replicate these steps.

 

Thanks!

It looks like the texture of the original object was assigned to the class. See in your first screen shot the the OIP say Texture: By Class for the desktop and None for the circle.

 

What you did is fine, but if you have a bunch of parts that need to be textured the same, you could put them all in the same class, assign a texture with transparency to the class and then tell the objects to use the Class Texture.

 

Glad you got it working.
